Numerous Makes of Tipping Gearand Moving Floor in Popular Use. A Wide Range of Models Available for Dealing with Practically Every Load
Capacity
WITH haulage rates at the present low level, it is certain that, without . Mechanical aids to loading and unloading, many transport contracts would be unremuneratiye. It is vital in profitable haulage operation to keep the vehicle at work for the maximum number of hours per day and to minimize terminal delays. One of the surest means to this end is the fitting of efficient tipping gear or a moving floor.
Both types of mechanical-handling device have their special uses, although the moving floor has the advantage that it can deal as easily with goods in sacks as with loose loads, such as sand. Striking evidence of the time-saving properties of the moving floor is furnished by Transport Engineering, Ltd.
A device supplied by this company to the Cement Marketing Co., Ltd., is said to have discharged a load of 17
c46
tons of fine sand in less than half a minute. I n another case, a Unipowered Fordson, with a Transport floor, run by John Mowlem and Co., Ltd., loaded, shifted and diecharged in a week of SO hours 1,788 cubic yds. of material in levelling a site.
So far as tipping gear is concerned, the handoperated pattern is, perhaps, the more suitable for the general carrier who requires to use the gear only occasionally. In other instances, the saving in time effected by power gear might well justify the higher first cost.
Anthony Hoists, Ltd., has, in a comparatively short time, secured a firm footing in the market for high-class tipping gears and offers two types. One is a, slanting pattern, the other having a horizontal ram and cam action. No high-pressure pipes are used, whilst the fitting of a piston obviates the need for cup leathers. A special feature is the incorporation of a shaker device to dislodge the load when in the fully tipped position. For work on which an almost perpendicular lift is required, there is available a gear affording the remarkable maximum tipping angle of 82 degrees. Anthony hoists and electrically welded steel bodies are now fitted "as standard" to Fordson chassis.
Apart from marketing hydraulic tipping gear and power winches, Bromilow and Edwards, Ltd., now makes the Principality moving floor, which is suitable for a wide variety of uses, including refuse collection. Remote operating gear can be fitted, so that the man may stand clear of the load when discharging. A noted B. and E. product is the Gigantip elevating and tipping equipment for unloading and stacking.
William E. Cary, Ltd., markets a patent unit for converting hand screw or rack gears to power operation.
, Although the Clayton Dewandre Co., Ltd., is particularly noted for its braking system, the concern also makes efficient rack-type tipping gear and hydraulic equipment. The rack gear is for hand operation and is suitable for fitting to many classes of vehicle. The hydraulic apparatus provides an angle of tip of 50(JO degrees.
Certain of the Dennis refuse collectors embody a moving floor produced by Dennis Bros., Ltd. A barrier is attached to the rubber floor and provides an efficient means for compressing t h e load.
In addition to the usual types of hand operated screw and hydraulic end and sidetipping gear, the Eagle Engineering Co., Ltd., manufactures a gear for elevating the, superstructures of tower wagons, which is claimed to reduce by over 75 per cent. the time required to raise the tower, as compared with the use of hand gear. Hydraulic tipping gears are available in both single and twin-ram patteMs and afford tipping angles of 40-45 degrees.
A wide range of gears is marketed by Edwards Bros. (Tippers), Ltd. There are a unit-constructed hand telescopic apparatus weighing about 211; cwt,,. three models of power-operated hydraulic telescopic end-tipping equipment for loads up to 8 tons and a twin-ram hydraulic power gear for three-way tipping of loads up to 5i tons. An important feature of Edhro power gear is a wobble-plate pump.
Sir George Godfrey and Partners, Ltd., is now handling the Theed pneumatic hoist, which is claimed to be the only apparatus of its kind in this country.
Inexpensive screw and hydraulic gears for hand operation are marketed by Joseph Lea and Sons, Ltd. Features of the screw type are a selfaligning ball nut for the body bracket, a safety ratchet on the winding shaft and enclosed bevel gears. The hydrau lie pattern has only one external pipe.
Another maker of hand gears is Henry Lowe (Lifts), Ltd., who offers both single-screw and telescopic models at attractive prices. A maximum lift of 6 ft. is afforded.
Straightforward, sturdy design characterizes the tipping apparatus produced by Parkside Engineering Co. (Liverpool), Ltd. The most popular gear is the hand-operated 2-3-ton pattern, which is particularly suitable for Bedfords, Fordsons, etc.
Messrs. John Perks and Son are another firm who make low-priced single-screw hand-tipping gear, with a length of screw up to 5 ft.
Under the name of Apkoway, J. W. Pickavant and Co., Ltd., also markets hand-operated apparatus of the telescopic and single-screw types.
Water pressure is used to operate the tipping gear manufactured for some years by the Sentinel Waggon Works, Ltd. A vertical tipping cylinder is mounted rigidly in the chassis, water pressure under the ram causing the body to rise.
Another vehicle manufacturer producing a moving floor is Shelvolle and Drewry, Ltd.
Screw tipping gears of the single and telescopic types for end and side discharge are specialities of the Spenborough Engineering Co., Ltd. In the three-way gear, the need for pipes and universal joints is obviated by. the use of a swinging lifting arm. Maintenance costs are claimed to be particularly low.
The Weston tipping gear, manufac
tared by Sunsaloon Bodies, Ltd., is a good, light, hydraulic telescopic type incorporating a two-plunger pump driven directly from the gearbox and an ingenious locking device to prevent the body from lifting at the front.
The well-known moving floor made by Transport Engineering, Ltd., has recently been improved and is now formed of pressed-steel slats of patent design, sherardized to prevent rust. and linked together in such a manner as to provide a tightly sealed, but flexible, surface. Lubrication is effected automatically.
Rock is the general trade name under which the various models of poweroperated hydraulic tipping gear made by the Truck and Tractor Appliance Co. (Manchester), Ltd., are marketed. In addition to the 2-ton, 3-ton and 5-ton types (for each end or three-way tipping), there is a special heavyduty end-tipping gear of 8-ton capacity. • Force of gravity is used to operate the tipping gear supplied by Tuke and Bell, Ltd.
The wide range of hydraulic tipping apparatus manufactured by the Wood Hydraulic Hoist Co., Ltd., covers capacities from 2-14 tons. Moving parts are few and all work in oil, whilst there are no cup leathers or oil tanks. The gear is .rapid in action and affords a tip of 50 degrees.
