FACILITATE
SALVAGE
THE urgency of salvaging a wrecked or disabled vehicle makes it essential that efficient arid specialized equipment for the task should be readily available to those whose duty it is to attend to the machine. Large operators, such as bus companies, whose vehicles cover only short radii from headquarters, often provide their own breakdown outfits, but, where long journeys are concerned, it is usually necessary to rely upon the assistance of a salvage specialist. But, however the removal of the disabled vehicle is effected, the equipment employed must be conducive to rapid work, as well as being capable of withstanding arduous service under a wide variety of conditions. Such appliances are marketed by several well-established concerns and a résumé of the salient features of each make provides, interesting reading.
Perhaps the most important item of equipment is the crane, which mitt be capable of withstanding considerable dead loads and must have a reasonable reach, for when mishaps occur, vehicles do not always fall into positions that ease the work of the salvage gang.
Harvey Frost and Co., Ltd., markets several models of crane, including two capable of lifting weights of up to three tons and eight tons respectively. The 3-ton pattern incorporates two hoists, each capable of raising 1k-ton and operated independently, whilst swivelling heads facilitate the salvage of vehicles in awkward positions. A 30-ft. run-out of cable is provided.
The 8-ton type has a swivelling box and is most massive. A useful feature is that the rear drum provides an anchorage cable to "counterbalance the load when a full eight tons is being lifted. The price of the outfit, complete with all auxiliaries, is £85. Another useful appliance is the " dual " type of H.F. crane, which can be folded back against the cab.
An 8-ton crane is also marketed by the Equipment and Engineering Co., Ltd. This has two jibs and provides a radius of 5 ft., with a clear lift above the ground of S ft. The hook can be lowered 14 ft. below the level of the ground upon which the breakdown lorry is standing.
Turning now to the cranes made by Mann Egerton and Co., Ltd., there are models for 30-cwt. and 21-3-ton and 5-ton loads, and some of these can easily be operated by one man. A. 30-cwt. collapsable jib is also marketed, this being available in special sizes to suit particular lorries. The price is £10 10s. The 21-3-ton model is of the overhungbridge type operated by racket-checked gear.
The Service Equipment Co., Ltd. markets 21-ton and 3/-ton models. The former has a triple chain which lifts the load through a 6-to-1 gear ratio and the height and overhang of the boons are easily adjusted by telescoping the bar, which is locked in position by means of a pin. The price is attractive, being £18 10s. The 3i-ton pattern costs £27 10s. and embodies a swivelling nose, which permits the chain to adjust itself to the angle of pull.
R. FE. Cook and Co., Ltd., has three cranes to offer, these being of 2-ton, 3-ton and 5-ton capacity and costing respec tively 5s., .£15 Sc..and £49. The smallest type gives an overhang of 4 ft. The 3-ton and 5-ton types embody tilt screws which enable the jib to be raised or lowered, when carrying a load, with a minimum of effort.
Messrs. Youngs market several models of crane, there being two substantial types to lift 2-/ tons and 5 tons respectively. Thera is also a swivelling davit crane for lighter loads and an easily removable jib for 30-cwt. burdens.
The next item of equipment that comes to mind in connection with breakdown outfits is the towing ambulance. This chould incorporate a pole sufficiently long to enable sharp turns to be negotiated without difficulty, but, at the same time, allowing the towed vehicle to be conveniently close to the prime-mover. Other desirable features are low height and extreme stability.
These and other requirements are fulfilled by the )1,F. appliances, which are designed to bear loads of two, three and five tons. In the case of the 2-ton model, the crutches, which are mounted on a turntable, are laterally and vertically adjustable, whilst, with the 3-ton appliance, they may be swung around independently, as well as being adjustable. The large model is particularly interesting, as it incorporates new and patented features, whilst the wide spread of the crutches provides great stability. '
The Mann Egerton ambulances are built for 1-toil, 24-tou, -tou. and 5-ton loads. The lest-named is mounted on strong double solid-rubber tyres, and the 3-in, axle is equipped with adjustable tapered-roller bearings. The crutches are adjustable for width and height, the jaws being self closing. The prices of the four models are respectively 111 10s., f15 10e., 121 and £56 10s.
The Equipment and Engineering Co., Ltd., offers a 5-ton ambulance, which has a track of 3 ft. 6 ins, and a maximum length of 13 ft. 6 ins. The crutches are adjustable for width and height and have self-closing jaws. The company states that it can supply a free-running wheel for use in conjunction with the ambulance, in cases of trouble causing locking of the back axle. The R.H.O. towing •ambulances are in two models, one having plain bearings and the other roller bearings. The towing pole is 6 ft. 0/ ins, long when closed and 11 ft. 0/ in. in the extended position.
We will now deal collectively with towing poles, distance bars, winches, supporting jacks for steadying the salvage vehicle when it is at work, special jacks for breakdown duty, etc.
All of this equipment is to be found in the HZ range. There is a 7-ft. 3-in, pole available at a cost of £1 18s. 6d., and a 7-ft. 10-in, telescopic device, of great strength, at a
correspondingly higher price. The distance bar incorporates double-acting shock absorbers. Supporting jaatvare sold by the pair and cost 1.1 5s. 6d.
The Mann Egertoh towing pole can be supplied with eaststeel eyes or clamps and is claimed definitely to prevent overrunning by the towed machine. Universal joints are fitted at each end of the device, which is adjustable from 10 ft. to 14 ft. Another useful item of equipment in this company's extensive range is a steering lock, which ensures that the front wheels of a vehicle that is being towed tail forwards, trail correctly. Two models are listed, costing respectively £1 15s. and £2 15s. Winch gear and jacks also figure in the Mann Egerton range. Another interesting device is the 116w Tangye 5-ton screwjaelt, which has been specially designed for salvage work.
Its height when closed is 2 ft. ;I Ins. and the appliance provides an effective lift of 1 ft. 5 ins, For vehicles having the usual type of disc wheels the method of operation is to place a special semicircular plate over the securing nuts of the wheel. Each nut is removed in turn, a cone washer being placed over the stud and the nut replaced. A sling is then placed over the jack crutch and is fixed at each end to the wheel, when lifting may be commenced. The whole tackle costs 19. The wholesale distributors for this useful appliance are Messrs. R. Cadisch and Sons, the well-known factors.
The R.H.C. towing -pole is equipped with a coil-spring shock absorber and has an overall length of 7 ft. 4 ins. Other useful items of equipment in the R.H.C. range are a steeling clamp costing 8s., a double sling chain and a universal winch. This company's range of salvage equipment is particularly comprehensive.
In conclusion, ono must not overlook the Bedford Good Samaritan, which is built as a standard model by Vauxhall Motors, Ltd., with a body by Spurling Motors. The equipment is of H.F. make and is sufficiently comprehensive to meet all needs.
