A TIPPER is a tipper is a tipper. It may be regarded as the most basic of all load-carrying vehicles in terms of the work it has to do and in many cases the variety of loads it has to carry. It may be still the most abused type of vehicle on the road but since the regulations have been more strictly enforced and since the advent of hgv licensing of drivers, its role has assumed a certain dignity of purpose that has given it a new status.

Typically, it has to carry low-grade materials and this increases the importance of selecting the right type of vehicle for the job as a means of reducing wasteful running to a minimum. And more often than not the major consideration is the use of a type of body and tipping gear that matches the vehicle on which it is mounted as well as the

load it carries and the conditions of service, with due regard to the experience, capabilities and character of the drivers.

While the majority of run-of-the-mill tippers are nominally non-specialized vehicles, virtually every tipper operator's job is specialized to some extent. And although practically all bodybuilders produce a standard body or range of bodies to their own design or based on a kit of sections, they rarely build two or more 'bodies for different operators that are exactly alike apart from standard ranges for short-wheelbase tippers. And even the operators of short-wheelbase vehicles often "want something different" when it comes to detail.

How often does the bodybuilder know best what is suitable for his customer, the operator? In many cases he provides ; useful and reliable consultancy service notably with regard to payload potentia and the stability of long tippers. Som. operators know what they want and hay. the money to pay for it. A substantia minority would do well to rethink thei operations and Make a fresh start if the: could raise the cash. Operating a tipper on shoestring is no longer viable.

On these pages we take a look at som tippers which are either purpose-built to th operator's special requirements or whic have some particular feature or fitment c note, often at the specific request of th operator. Others in this section, while not ner or special in themselves, are interesting ft the way in which they have been applied t particular jobs, and the reasons why the have been chosen.

Skelton Ltd, Mill Lane, llongley, Warwickshire, is equipped with a iecial Skelton /VVelford covered tipping body 'oduced by Welford Engineering (Oldbury) d and is tipped by an Edbro 4LN single-ram iar, slurry being pumped into the vehicle )m a settling tank. The sloping tailboard (5) operated by a pneumatic system designed

Harry Skelton which provides quick iloading as well as cleanliness and will be ted to all Skelton tippers in due course. Arry Skelton points out that slurry is irmally carried in conventional tankers that ive a payload of about 8 tons when ounted on a 20-ton vehicle. It will be noted at the rear light and number plate are indantly mounted on a section of rubber fting which is said to reduce the frequency damage by 90 per cent.

3en tipping bricks at the end of a run, this 3dford TK /Reynolds Boughton converted x-wheeler is operated by J. and A. Jackson d, brick manufacturer of Manchester, and is rted with an Edbro drop-sided wood body hich has a length of 15ft to cater for the irriage of bricks on pallets as well as loose icks. A length of body that is exactly atched to the overall length of the pallets abilizes the load and obviates damage to e bricks. The wood floor, side boards and ilboard are steel lined. Rated at 17 tons oss, the vehicle can carry a payload of 91 ns, but normally operates wan a reduced ad. In the case of 16-ton-gross tippers in e fleet, composite aluminium /wood /steel idles are employed to provide a reduction in eight and enable a higher payload to carried. 7.

Operated by the Judkins Granite Co of Nuneaton, the Foden 24-ton eight-wheeler in this picture is six years old and was recently equipped with an Alusuisse M Series welded aluminium tipper body from a kit supplied by the Star Aluminium Co by a three-man bodybuilder, F. A. Gosling Ltd, of Nuneaton. The Edbro outrigged underbody rams and the hinge pins of the original assembly are retained in use, the thrust of the rams being transmitted to the central runners of the body substructure. The 18ft 6in. body has a length of 7ft 9in. and a height of 3ft. It was built in less than 14 days by two men with the occasional help of a third man. Band 9.

Tom Byatt lEngineers) Ltd, Fenton, Stoke-on-Trent, says that an aluminium tipper body normally has about three times the life of a steel counterpart, while it costs about twice as much. Fitted with a special cab-protecting canopy, the scow-ended welded steel body of the Bedford KM 16-tOn tipper (8) has a capacity of 11 cu yd and can carry a payload of 10 tons. The 28ft welded-aluminium monocoque body that is seen mounted on an M-and-G 32-ton-gross semi-trailer (9) has a capacity of 35 Cu yd and can legally carry a load of 25 tons, an aluminium body being some 40 per cent I lighter than a comparable steel type. Both I types of body are tipped by an Edbro front-of-body gear providing bottom lift. The aluminium body is available in lengths up to 34ft and optional equipment includes barn doors, side extensions and heavy-duty flooring.

The operator of this tipping vehicle, L. T. Shaw of Great Barr, Birmingham, required a maximum load four-wheeled drop-sided tipper with a low centre of gravity, a maximum-length floor and ample ground clearance to enable him to combine general haulage with tipping work to the best advantage. He approached Welford Engineering of Oldbury, Staffs, and this drop-sided tipper (10) was produced for his company with a non-standard twin-ram underfloor tipping gear (11) that is a short-stroke four-stage gear, the use of which gives a reduction in floor height of 7in. without reducing the ground clearance. The all-steel body has a length of 15ft 6in. and is mounted on a Dodge K1050 16-ton-gross chassis, its cubic capacity and payload being 10 cu yd and 10 tons respectively. Because of the space saved at the front of the body by using an underfloor gear, the bottom-hinged tailboard can be let down to provide additional length without infringing the regulations when the vehicle is used for general haulage. It is claimed that the relatively low centre of gravity of the vehicle reduces spring breakage on site work.

This Neville Industries Super Ratesaver 40 cu yd tipping trailer (12) is one of three similar vehicles operated by George M. Read of Wilderness Quarry, Micheldean, Glos. George Read states that the vehicles have solved his tipping problems by eliminating the turnover risk with sticky loads. Retracting the wheelbase enables the vehicle to be • manoeuvred in confined spaces and to b weighed as a complete unit on under-lengt weighbridges. Barn type tail doors (13) ar firmly clamped in the closed position by hinged channel member and the doors giv ample support to the load without the use of cross-bar, which would be unacceptablf While the trailer is rated at 32 tons gros! its gvw is 28 tons when coupled to a For 01000 tractive unit and' it has a servic payload of 18 tons. It is tipped by an EMI' 6SC single-ram gear. The vehicles carry soli fuel, metal scrap, slag and pitch on route covering the West Country, London and th Home Counties a nd areas in the Easter Counties.

Based on a Ford D1000. the body tipped by an Edbro W4 underbody ge. having air control.

The Alusuisse M4 series are all-welded aluminium tipper-bodies that have been specially designed for extra toughness to outlast most of today's bodies. How ? By the use of extrusions designed for the body, and alloys matched to operational requirements—alloys which are corrosion resistant and therefore need no painting. The result is a complete body made up as an integrated structure without local weaknesses, to handle rough, tough jobs in arduous conditions, year after year, and giving maximum payloads. Combine with this the lightweight properties of aluminium, and you have maximum durability for minimum weight penalty.
