trucks without the assistance of ramps may find wider applications in dealing with other kinds of traffic. The tipping gear raises the body in a slanting attitude, so that the under-lip of the tail is higher than 8 ft. 3 ins, from the ground—the height of the side of a railway wagon.
The action of the lifting gear can be seen in the accompanying illustration. It should be noted that as the body is raised, the centre of gravity moves slightly towards the centre of the vehicle, instead of to the rear. This improves stability, although the vehicle is not suitable for tipping on rough ground.
The complete weight of the tipping gear, body and subframe is only 33 cwt. A special feature is the provision of a stabilizer at the rear of the chassis and body.
Edwards Bros. (Tippers), Ltd., Bolton, constructed the body and underframe on a Bedford long-wheelbase chassis and incorporated Edbro 3T gear with six-cylindered awashplate combined pump and power take-off. The rams have a triple extension to provide the high lift required.
With a 5-ton load, the body can be raised in 45 seconds. In the normal position. the loading height is 4 ft. 5 ins. The wooden body is an Edbro type 2 with drop sides and detachable centre pillars. The floor is lined with sheet metal and a cab-protection extension is fitted. The tailboard is hinged at the bottom and, when opened to a horizontal position, forms a chute to enable tipping to be effected accurately.
Simplieity was the aim of the design, which embodies standard tipper parts and can easily be maintained. The vehicle was supplied by the Chester Engineering-Co._ Ltd., City Road, Chester, a company of the Braid group,
