Saving the Time of the Vehicle by Means of a New Goods Transporter Capable of Handling One Ton Loads.

IN THE transporting of goods there are many stages. One of those stages, the actual conveyance or haulage upon the road, has, since the coming of the motor vehicle, undergone a great improvement in the matter of seed and general efficiency. It has become more and more urgent that the other stages in the transport of goods should advanee, and the more immediately important of these concerns the conveyance of the goods from the storehouse or warehouse to the lorry, and wain from the lorry to the next paint of deposition. The ordinary hand truck or barrow, by which a package .within the capacity of the man pushing the truck can be moved, is not only an inefficient vehicle because its operation is slow, but it entails the expenditure of a

much greater man power per ton of goods. By means of the hand truck a man -can only move a few evrta of load at a time and, whilst the loading and unloading of the truck take place, there is involved an expenditure of the time of tie man who has to stand idle whilst the load is being placed upon or removed from his truck.

This fact has called into use a type of truck which is separate trcin the load-carrying platform, and which will handle one-ton loads. A number of plat -forMs, can be used in connection with eachtruck, some being loaded and some being unloaded whilst one is en route between the warehouseand the vehicle. A new truck of this type is the L.A.C. hydraulic one ton truck, which has just been placed on the market ,by Hydraulic Trucks,: of 25, Pancras Road, London, N.W.I.

Our illustrations show the traick unloaded and also in actual use, a sectional drawing being included of the hydraulic ram and control mechanism for the lifting of the loaded platform from the ground.

The L. A.C. hydraulic truck is built of ste6I throughout, excepting the wheels, which are of strong cast-iron, and the hydraulic, ram body, which is of gun-met4 The under-frame is built up of steel cast

mg and channel steel, the steering head is also composed of a,' steel casting, whilst the lifting frame is of steel angle section. The lifting frame is carried on four rollers, two engaging in a couple of sloped slots in the two under-frame casting-s, and two running an inclines immediately over the back axle. The iusweeping of the lifting frame at the rear brings the wheelbase at the rear to the full width of the truck, thus ensuring stability. The, lifting mechanism consists of a powerful

hydraulic rani and new patented valve of the dual type. The handle is pivoted on th,e front axle, and its lower fork has two arms extending rearward, from which, through a link action, a small diameter pump is given a vertical movemeut through the steering head by a 'motion given to the truck handle. Five motions of the handle are sufficient, and at each stroke fluid is drawn from the reservoir above the ram and forced to the operating side of the ram, thus lifting the latter, which, in turn, lifts the platform and its load, the total amount. of lift being 3 ins. The operation of the listing gear is extremely simple, the handle being free at all times, so that-the man's ability to manceuvre the trucli is not in the slightest degree affected. A pedal lever, with plates on either side of its fulcrum,, serves to operate the valve gear, pressure on the forward plate opening the villve and releasing the fluid from the offside of the ram and permitting it to flow into the reservoir above the ram, a couple of Coil wings assisting this operation and lowering 'theload to floor level. - In confined spaces, where the load has to be picked up close to a wall, it is quite easy to manceuvre the truck in under a load-carrying platform and, by turning • the' front wheels to any convenient angle, the handle can be given its pumping action in order to lift the load.

With regard to the inanceuvring of the truck, we found by actual experiment that it was extremely easy to guide the truck under the platform, however the latter may be disposed. All that was necessary was a. little more than the width of the, truck between the platform and the wall ; except for this reserve.tion, it might be said that a loaded. platform. could be picked up from any position.

A very great point about the L.A.C. hydraulic truck is that not only can the load be pulled, but it can also be pushed with equal facility, which is not usual with this type of track. This is effected by the engeeing of the handle with what is known as the wheel fork on the steering heed of the machine, the handle then being quite upright. We found it was

A brake, having a pair of wide brake &noes, one operating on each front wheel, is fitted, the lever coming immediately below the cross handle in a most convenient position. With efficient brakes, a ton load can controlled easily down quite a difficult decline, whilst, of course, the truck can be instantly brought to a standstill regardless of the position of the truck handle at any time.

The L.A.C. hydraulic truck is made in three sizes, capable of dealing with platforms of the following dimensions: S19 truck wi2l'handle platforms of 48 ins. by 36 ins, maximum and 30 ins. by 24 ins, minimuni; truck S29 will handle platforms 60 ius. by 48 ins. maximum and 40 ins, by 32 ins. minimum ; truck S39 will handle platforms 72 ins. by 54 ins. maxiirrim and' 48 ins. by 38 ins. minimum, their respective weights being 300 lb., 330 lb., and 360 lb. The whole of these models are capable of handling one ton loads, and each one is tested with a 100 per, cent, overload, that is to say, a load of two tons, and they are guaranteed unbreakable under all reasonable conditions for loads up to and including one ton.
