A buyer's guide to trailers and semi trailers


Arrow Construction Equipment Ltd., Cowpen Road, Blythe, Northumberland.

A substantial range of standard semi-trailers is offered, including flat, step and drop-frame units, machinery carriers, skeletals and vans. The flat platform types can be supplied with single-, tandemor three-axle running gear; all others with only singleor tandem-axles.

Special tilting trailers are produced for the carriage of civil engineering plant. There are two versions of this type available, one a close-coupled drawbar unit of 10 tons capacity and the other a semi-trailer of 16 tons. The system employed by these vehicles is a hydraulically tilted body or part of a body which forms a ramp up which diggers, bulldozers or cranes or the like can be driven or winched. Loading times of 45sec for the drawbar vehicle and 90sec for the semi-trailer are claimed; both platforms tilt to 14deg and both units cart operate at maximum permitted motorway speeds.


Boden Trailers Ltd., Royton, Oldham, Lancs.

The Boden Mk 3 semi-trailer frame forms the backbone of this company's products. Nearly all the variations produced utilize this model as their base. Among the variations available are flat platforms, step and drop-frame, skeletal container-carriers, coil carriers and vans. Some of the features of the range are that it includes non-reactive suspension on the tandem models, chassis frames are of fabricated l-section beams with specially designed stiffening plates in the regions of the spring hanger brackets and independent lighting harness to each side of the vehicle are provided. Single tandem and three-axle units are included in the range.

Boden also offers a wide range of TIR bodywork on these trailers, all tilt-framing being designed to be interchangeable between any units made by the company. The alloy-bodied chassis-van is constructed with Alcan alloy transport sheet which has close pitched ribbing. This is ranged horizontally giving an attractive finish. With the amalgamation between this company and Crane Fruehauf, Baden recently announced the introduction of a chassisless van incorporating the Crane Vanguard body arid the Mk 3 Boden running gear. Bramber Engineering Ltd., Durban Works, Willand Works, nr. Cullompton, Devon.

The majority of this company's production is taken up by lightweight boat trailers and other special vehicles for the transport of road rollers and cars. Bramber Flexitor suspension is widely used by manufacturers of small trailers throughout the industry but it is not generally recognized that these are available with capacities of up to BOcwt per pair.

Production under licence of the Rockwell Standard single-taper leaf spring was recently started at the company's South Wales works,


J. Brockhouse and Co. Ltd., Vehicles Division, Victoria Works, Hill Top, West Bromwich, Staffs.

Fifth wheel and automatic coupling semitrailers provide a complete range for all aspects of general haulage operations. The Brockhouse automatic coupling is of the non-collapsible variety and trailers so fitted are equipped with dual mechanical and twoline air braking systems complying fully with the requirements of the C and U Regulations.

Fifth-wheel trailers go by the name of Expediter and this range contains single-, twin oscillatingand tandem-axle versions. The twin oscillating-axle designs employ trailing-arm suspensions utilizing compressed rubber as a suspension medium. The single-axle units have conventional leaf springs with an option of Dunlop Pneuride air suspension. A light weight mechanical non-reactive suspension is employed on the tandem-axle versions providing lower tyre wear and improved braking.

The company's design and production facilities permit considerable variation of existing models and a high degree of custom building.


British Trailer Co. Ltd., Phoenix Works, Richmond Road, Trafford Park, Manchester 17.

Four-In-Line running gear tractors make up a large proportion of the output of the BTC range. This running gear can be found operating throughout the world and employs fourspring suspension with the springs situated above and below each oscillating axle. The axles carried on trunnion-brackets and the centres of the axle stubs and the trunnion are on the same level, thus allowing universal movement without tyre scrub.

Many types of trailers made range from straight frames, through step and drop-types to machinery carriers, pole trailers, skeletals, coil carriers, vans, tippers and bus trailers. This latter category is for airport authority use and does not comply with regulations for highway operation in the UK. They have accommodation for up to 100 passengers.

Bogies and dollies for indivisible loads and drawbar units with gross-trailer weight ratings ranging between 5.6 and 28 tons are produced. BTC has a wholly-owned bodybuilding organization which produces special bodies and containers both of ISO and Freightliner types. It is one of the few trailer companies that makes its own fifth-wheel couplings.


Carrimore Six Wheelers Ltd., Harelaw Industrial Estate, Stanley, County Durham.

In the last year this firm has moved its works lock, stock and barrel from Finchley, North London, to County Durham, allowing trailers to be built more competitively. But this does not mean that the numerous special types produced over the years will be dropped. Carrimore is the trailer division of the Steel Barrel Scammells Group and as such can supply a wide variety of special bodywork including tankers, tippers and exhibition vehicles.

The company is a leading supplier of car transporters and its three-decker—the K5—is probably the most sophisticated vehicle of its kind available. One of the unique features of transporters made by this firm is the Carrimore Quickfit retractor coupling. This device extends the distance between tractive unit and trailer when the vehicle is turned, so allowing smaller body, and back of cab dimensions to be utilized. An extra advantage claimed for the coupling is that it reduces the tendency of jack-knifing. It is available on Carrimore semi-trailers up to 16 tons gross trailer weight only.

Articulated special-purpose vehicles are offered for gross combination weights between 6 and 60 tons and drawbar units for gross weights between 2 and 70 tons are also made.

Extensible units with gross trailer weights between 12 and 26 tons, pole trailers between 10 and 30 tons and skeletal container-carriers between 12 and 26 tons are made. The company also produces vans of 13 to 28 tons gross trailer weight.


Carter Engineering Co. (ramworth) Ltd., Lichfield Road, Tamworth, Staffs.

Car transporters are the speciality and vehicles for this purpose are produced both as semi-trailers and as close-coupled fourwheelers.

All the units made by Carter utilize rubber as the suspension medium and the company has made blase studies of existing and future legislation with a view to its products carrying the greatest possible number of cars while operating within the legal limits of gross weight and overall length.

Units which are equipped with two decks have the upper sections raised and lowered by either electrics or hydraulics, according to preference. The biggest transporter carries eight cars and the smallest—a close-coupled four-wheel drawbar unit—carries two.


Charrold Ltd., St. Peter's Road, Huntingdon.

Special trailers—for handling bulk granular materials—and stainless steel vans are made by Charrold.

The bulk vehicles all embody frameless construction and utilize many types of materials handling equipment. These can be of the belt conveyor type, elevator, gravity or pneumatic delivery—in fact any system to suit the customer's requirements.

Constructed on the frameless principle, the vans utilize corrugated stainless steel panels. Fitted with standard leaf spring suspension, they are available with single taper-leaf springs as an option.

Both the vans and the conveyor vehicles are available with single-, tandemor threeaxle running gear. Tanker bogies are produced with singleor tandem-axles.


Crane Fruehauf Trailers Ltd., South Green Works, Dereham, Norfolk.

If a very heavy transporter is seen on the roads it is probably a Crane Fruehauf unit. Special units of this type weighing 400 tons and over are produced and these usually incorporate hydraulic suspension. The hydraulics serve two purposes—the first to absorb irregularities in road surfaces, the other to raise and lower the unit to facilitate the negotiation of bridges, loading and off-loading.

A wide range of standard platform trailers both with flat frames and step frames is made also, the flat types being available with single-, tandemor three-axle running gear. All these models have conventional suspension, the springs being of the slipper-ended type with the axles located by radius rods.

Pole trailers and round-timber carriers are produced and singleand tandem-axled coil carriers, tipping trailers and tankers. are also made. The company has developed the Vanguard range of standard frameless vans. These can be equipped for dry cargoes or be insulated and /or refrigerated. Bulk powder transporters, utilizing air fluidization for discharging, are constructed in both light alloy and mild steel. Tankers for liquid cargoes can be supplied in these materials or in stainless steel.

A standard range of machinery carriers with gross trailer weights between 12.75 and 72 tons is produced. .Other vehicles of this type can be made to special order. TIR-bodied flats and flat platforms of the extensible variety are made also.

Recent changes in the firm's designs for the Con-Leader container carriers have resulted in these models now having a continuous frame all round instead of relying on outriggers to carry the container locks. Other developments in this range now permit the carriage of two different sizes of ISO container and three sizes of Freightliner. This addition to the range is alternative to the original Con-Leader units which could carry only one size of container depending on the length of the trailer.

The latest introduction by Crane Fruehauf is a new axle which is now used as standard equipment on all standard semi-trailers. This unit features a square beam rated at 25,000lb and has equal size inner and outer bearings. Lubrication of these units can be either by oil or grease and the new bearing dimensions are claimed to provide for a 25 per cent increase in capacity.


Crawford, Prince and Johnson Ltd., Syston, Leicester.

No semi-trailers are manufactured by this company but building of bodywork for vehicles of this kind is undertaken. Trailer production is restricted to two-wheeled drawbar types with capacities of up to 15cwt. Special types are produced to carry sheep and pigs and lightweight units suitable for towing behind light cars or motorcycle combinations are made.

Custom building of trailers for special purposes is undertaken.


Dayton and Co. (Coachbuilders) Ltd., Wilden Works, INilden Lane, Stourport-onSevern.

This company offers an extensive range of standard trailers of many types covering gross trailer weights of 6 to 30 tons. Flat trailers are produced on single, tandem, three-axle and twin-oscillating axle running gears and machinery carriers on single-axle and twin-oscillating units. The remainder of the models offered are mounted on either singleor tandem-axle units and these include step and drop-frame trailers, extensibl es, skeletal container-carriers, coil carriers and vans.

R. Dixon-Bate Ltd., Chester.

An extensive range of lightweight drawbar trailers and small articulated types is offered. Among the models are several semi-trailers, some designed for operation with converted Land-Rovers, and tankers with capacities between 100 and 1,000gal, The company also produces a wide range of trailer equipment.


Duramin Engineering Co. Ltd., Harbour Road, Lydney, Glos.

Dura min is perhaps better known for its activities in the body building field. It does, however, produce an extremely wide range of trailers both of the semiand drawbar types and has recently announced a completely new range. Its products feature a wide use of light alloy. Three coil carriers having main frames constructed entirely of aluminium are offered: these units carry a bigger legal payload than any other vehicle of their type.

Four types of running gear are used on the Durarnin trailers, these being single-, tandem-, threeor twin-oscillating axle types. Singleand tandem-axled vehicles can be equipped with air suspension as an option. Van-bodied trailers can be supplied with dry cargo, insulated or refrigerated bodywork and tipping vehicles having either steel or aluminium bodies are also offered. Various types of bulk carriers for granular materials are made for weights from 15 to 32 tons and the company also offers a number of bogies for mounting on frameless tanks and vans. Drawbar trailers range between 10 and 32 tons gross.

Duramin also manufactures standard ISO and Freightliner containers, both of these being supplied in metal construction or a unique sandwich construction using expanded polystyrene with glass fibre panels vacuum moulded to it. The resulting assembly is strong, rot proof and insulating.

The new semi-trailer range includes seven skeletal framed container carriers for payloads ranging between 18 tons for the smallest to 32 tons on the largest, a 42-tonner.


R. A. Dyson and Co. Ltd., Grafton Street, Liverpool 8.

Production of this company varies from single-axle standard haulage trailers up to heavy and complex heavy haulage units.

Among the heavy vehicles produced are machinery carriers incorporating removable swan-necks and axle-gear which leave the load carrying bed completely free for loading. One of the features of Dyson machinery carriers is the use of high-tensile steel and special methods of construction giving extremely low unladen weight. A standard range of machinery carriers constructed in this way contains vehicles of up to 65 tons capacity.

The company produces a large number of oil-field trailers, most of these self loading and designed for the carriage of pipeline and drill

ing rig equipment.

A standard range of. single-, tandem-, and three-axle models is offered featuring steel or air-sprung suspensions. Three-axle models can be equipped with the Trailsteer self-tracking rear axle. This is the Italian Viberti unit which Dyson makes under licence in the UK. Among the suspension systems offered are the non-reactive DNR type and the Aeroride air suspension. This latter system is probably the most widely used air suspension in the UK.

Skeletal container carriers are produced equipped for use with ISO, BR Freightliner, or Lancashire flat type of containers. Some of these units are of the extensible type.

All the running gears used on other models are available as unitized equipment for mounting on to frameless tankers or vans and a wide range of converting and load-dividing dollies and bogies are available for use with long or indivisible loads.

A standard range of drawbar trailers with capacities from 8 to 16 tons for general haulage use is made, and also produced is a number of three-axle and other heavy duty types for special requirements.

Complete TIR trailers are produced, two features of which are removable intermediate decking and a travelling tilt, designed in Sweden and again, made under licence by Dyson. This eliminates the time involved in dismantling and assembling of fixed tilts.


Ibbeft Engineering Co. Ltd., Stanley Works, Kempston Hardwick, Bedford.

Automatic ground-level loading is the Ibbett byword. Most of its production incorporates the patented Eezion hydraulic retractable runun fling

ning gear, which allows the floors of trailers to be lowered to ground level without the need to remove either axles or swan-neck assemblies.

Those units which do not utilize this method of loading are equipped with tilting platforms and provide for the easy movement of wheeled and tracked plant. Articulated vehicles of the first mentioned types are produced with capacities of from 3 to 25 tons while the latter are available with capacities from 15 to 22 tons.

Also made: a wide range of close-coupled drawbar trailers on which the drawbar coupling-height can be varied between 23 and 36in. above the ground. Other products include vehicle recovery trailers and van trailers with capacities up to 1,500 cu.ft.


ECG Trailers Ltd., Silwood St., Bermondsey, London, SE16.

No standard models are produced—each vehicle is custom built to special order. Tenand 12-ton single-axle versions incorporating either the Tasker or Scammell automatic couplings are available and the company makes fifth-wheel versions of the 12-tonner. Rubery Owen axles and suspension are used throughout.


ERF Ltd., Sun Works, Sandbach, Cheshire.

Only one model is produced by ER F which is better known for its vehicles than for its semi-trailers. This one model, a tandem-axle unit with a 25/26 tons gross trailer weight Is made in 30 and 33ft length versions. Pressed high-tensile steel main-frames are used and these are boxed over 15ft of their length to provide adequate stiffness. Pressed steel outriggers, perforated to reduce the unladen weight of the unit, support pressed steel side-rave members, the whole assembly being electrically welded. A lin. nominal hardwood floor is laid longitudinally and has a removable trap giving access to the king pin assembly.

Two-speed landing gear is standard and the unit employs 15.5 by 7in. cam operated brakes with triple diaphragms at all wheels. Slipper ended springs and rubber bushing throughout the running gear eliminates the need for maintenance.


Fox Trailers Ltd., Victory Works, Woodend Avenue, Speke, Liverpool 24.

The most notable example of this company's products is the fold-over fifth-wheel converter. This enables a tractive unit to be used with either automatic couplings or fifth-wheel couplings; the preparation of a tractive unit so fitted can easily be completed by an operative working alone.

Almost any type of trailer or semi-trailer up to a gross trailer weight of 25 tons is produced by Fox although almost all of its production is made up by custom-built equipment. Twin oscillating, single-axle or tandemaxle running gears are used and an Eaton Hendrickson four spring suspension may be specified on the 16-17 ton models.

Integral vans have capacities of up to 1,600 cuft. Also made are tankers up to 3,600gal, semi-trailer and drawbar machinery carriers, and a number of industrial works transport trailers for internal use.


Fromant and Son (Trailers) Ltd., 97 Felpham Way, Felpham, Bognor Regis, Sussex.

The company has recently completed a number of special semi-trailers for transporting reinforced concrete slabs used in the construction of prefabricated buildings. These feature Rubery Owen suspension assembled with the axles underslung to provide a low centre of gravity. Inner and outer frames carry 17ft-long slabs and 24ft-long slabs respectively. The trailer frames are stepped behind the fifth wheel.

Fromant vans are of all-aluminium construction. TIR-bodied trailers and tipping trailers for operation at 32-ton gross are also made.


Hands Trailers ltd., Letchworth, Herts.

This firm, a member of the Hawker Siddeley Group, has introduced several developments of interest to those seeking low unladen weight. Its tandem-axle trailers employ Hands/ Neway running gear. This is a much modified and well proved American design which employs either air suspension or cantilever Leaf springs on the leading axle. The trailing axle is mounted on a trailing arm pivoted at its centre with its leading end bearing on the trailing end of the spring. This suspension is probably the lightest unit on the market: in running gear form ready for mounting on a frameless tank or van it scales 1 ton 18cwt. Also incorporated in the design are torsional anti-roll bars, of particular value when the suspension medium is air.

Of interest are the company's designs for skeletal container carriers, Weightsaver frameless vans (produced in conjunction with Bonallack) and container handling equipment. The skeletal trailer suitable for use with both ISO and Freightliner boxes has a cruciform framework which is designed to distribute the severe local stresses imposed when it is negotiating uneven surfaces while carrying a container.

A lightweight at-tic is produced utilizing a Ford D300 tractive unit. Detachable bogies, low loaders and machinery carriers are also built.

Hands offers load-sensed braking on all of its models, and it manufactures its own axles. An automatic coupling featuring an emergency braking system, operable in the event of the trailer breaking away from the tractive unit, is made. It is of the non-collapsible type and incorporates the largest diameter turntable available in this type of coupling.

Semi-trailers made have gross-trailerweight ratings from 6.3 to 36 tons. Drawbar types are available, these being of the twoaxle variety between 10.5 and 19.7 tans gross.


liaison Trailers Ltd., Newhaven, Sussex.

The AT6 is built to comply with the latest C and U Regulations and utilizes single-axle running gear with 8.25-15 tyre equipment. The AT4, which is the model number given to the close-coupled type of vehicle, is suitable for use behind a Land-Rover or Austin Gipsy type of vehicle.


Highway Trailers (Gt. Britain) Ltd., Multiwheelar Works, Southampton Airport, Southampton, Hants.

A wide range of semi-trailers for gross combination weights of between 20 and 32 tons for general haulage use is offered by Highway Trailers. Sixteen-inch by 5.5in. fabricated beams form the main frames of the bulk of these vehicles and a feature of the construction is that the cross-members are pierced through the web of the main frame. Hardwood floors are laid flush with the top flange of the main frame to accept direct loading of heavy items of machinery and the like, so avoiding damage to the floor boards.

Coil carriers up to 32ft-long incorporating a full length coil well are produced and the company also offers the Highway bulk tipper.

A three-axle semi-trailer for operation at 32 tons gross employs an unusual wheel arrangement, the first and third axles of the bogie being equipped with single tyre and wheel equipment while the centre axle has twin wheel and tyre equipment. Balance beams of unequal length distribute the load accurately over the tyres and the design is claimed to reduce the amount of tyre scrub.

The associate company of Highway, Multi-wheeler, produces this and other special vehicles. Made under licence by the company is a power-operated landing gear utilizing air over hydraulic which can be supplied either as a fitted unit or attached to removable fittings for handling containers. Highway also manufactures under licence Eidal running gear which is used on its round-timber carriers and bolster wagons.


Hoynor Ltd., Danbury Essex.

A car transporter which is quickly and easily converted into a general cargo carrier is one of the models offered by Hoynor. The vehicle —the Transloader--operates at 22 tons gross and has the upper deck arranged to fold down and form a 33ft-long platform.

Robert Hudson (Raleirux) Ltd., Raletrux Works, P.O. Box No. 4, Morley, Leeds.

Only one standard trailer is made by Hudson but also available is a number of dollies and bogies for indivisible loads and other types of trailer built only to special order.

The one standard semi-trailer is called the Timiser (from the words time and miser). This unit is a low-loader with a difference. It will carry a payload of up to 14 tons and the method of loading is unique.

Twin oscillating axles situated at the rear of the vehicle comprise two bogie-units, pivoted to allow them to swing out to the sides of the trailer. These are mounted upon ball bearing turntables and are coupled together by toothed quadrants. A locking pin is removed from the assembly and the handbrake lightly applied to the nearside unit. By reversing the vehicle a bias is created by the drag on the outside wheel of the nearside unit, forcing the two bogies to run outwards. With the load in place the vehicle is driven forwards and the bogies run back together when the locking pin is replaced. The whole operation is completed in a few minutes.

Among the types made to special order are 2,000 cu.ft. sugar cane transporters, 25-ton low-bed solid-tyred industrial types and road-going drawbar units with three-way tipping bodies, or standard flat or sided haulage. bodies.
