TIPPING wagons are particularly useful in dealing with certain materials handled by the builder or the contractors 'who supply the builder, as well as for work entailed by road construction..
The Halley tipper, which carries a, 4-ton load, is arranged so that over onethird of the body projects beyond the fulcrum point: The elevating gear is by twin screws at. the front, The Tilling-Stevens can be provided_ either with end or side-tipping bodies. In the gear-driven models theselevating gear consists of two single:screws at the front end, hut in the petrol-electric type the body is of the run-back-and-tip-over type, the gear being power operated. Several interesting types 'of gear are utilized on Thornycroft .chassis. The new aide tipper is quite a novelty, and was recently described by us in our page devoted to patent specifications. In another Vehicle a hydraulic ram is situated behind the cab, the connection to the body being by wire cables. Many of the Hanford vehicles supplied to builders are fitted with singlescrew tipping., gears, the screw being positioned between the cab and body. This gear is hand-operated and is of the makers' own design. Dennis tippers can be provided with hand-operated or hydraulic tipping gear. The hand-operated type comprises two telescopic screws positioned behind the driver's cab. The hydraulic type consists of a telescopic rain, also positioned. behind the cab.
In the Fiat lorry the hand-operated screw gear elevates the body from the C20 front end through the medium of two single strews. Perhaps the most interesting Leyland model is the short wheelbase tipper which can discharge its load to either side or to the rear. This type is marketed. in 3, 4 and 5-ton models. The gear is of the Bromilow and Edwards hydraulic type embodying twin rams, positioned approximately below the centre of the body. A similar type of three-way tipping ear is employed on some of the Commer Oar vehicles. Another type of Commer Car gear is shown in one of our illustra tions, and consists of two single handoperated screws behind the driver's cab. Another of our illustrations shows the Palladium side-tipping wagon, a number of which has been supplied to Trollope and Cells, Ltd., whilst Others have been einplpyed on building contracts in Chinas The F.W.D. wagon and trailer are particularly interesting, as the hydraulic rams utilized on wagon and trailer are operated by a single pump from the engine, the connection to the trailer ram being by means of a flexible tube.
We have already referred. to the 2-ton Austin tipping wagon. This can be sup plied with hand-operated screw gear, side-tipping gear of the balanced type, or hydraulic. gear for tipping in three directions.
One .of the. features of the Star tip-.
ping wagon is that it has a short wheelbase, which enables it to be accommo
dated on any public weighing machine. We must not omit to mention the particularly interesting typo of tipping gear fitted to the Sauter chassis. The gear is arranged so that tipping can be done
i
in three directions. It s of the hydraulic type and is .practically " foel-protd."
The Eagle Engineering Co., Ltd., are, of course. specialists in tipping bodies tots. of the side and end-tipping variety. The one which we illustrate on another page is of the side-tipping gravity type.
Another gravity side tipper which, whilst being very reasonable in price, has points of exceptional merit, is the Makrob, which is marketed • by W. and G. Du Criss, Ltd.
It is interesting to note that the Seam-. mell tractor lorry is now being sold as a tipping wagon for 10-ton loads. In the Albion wagon a Hele-Shaw pump provides oil for a telescopic ram at the front of the body.
As 'regards steamers, Fodens, Ltd., employ",a central hydraulic rain driven from the feed pump. A similar type, of gear is also employed on the Sentinel undertype _wagon, whilst the Atkinson has a telescopic screw situated at the front of the body and driven by a small separate steam-engine.
The Allchin wagon can be fitted with either mechanically „operated end-tipping gear or side-tipping body operated by hand.
The Mann gear consists of a curved. rack driven through a pinion by the. engine. The important feature is that
• the body is balanced.
Side-tipping and end-tipping bodies, power-operated by screw gear, are provided for the Clayton wagon • whilst telescopic screw or hydraulic end-tipping bodies and hydraulic three-way tippers are provided on the Ransome wagon.
