T O meet a demand for a maximum' load tipper which can be charged from an 8-ft. 6-in. hopper, Ryland Garage Ltd., Ryland Street, Birmingham, 16, have produced a special low-built 24-cu.-yd. body with an overall height of 8 ft. 51 in. for mounting on a new Atkinson eight-wheeled chassis with a wheelbase of 16 ft. 7f in. The general specification of the chassis is otherwise identical to that of the short-wheelbase model.
The height of the floor from the main chassis members has been reduced from the normal 15 in. to 61 in. by the employment of a modified front twinram tipping gear and by slotting the body cross-bearers so that the longitudinal runners can pass through them. After assembly the joints are welded.
The runners are of 6-in. by 3-in. channel section and the bearers are of 3-in. by 11-in. channel, the latter projecting 1in. above the top of the runners.
A Pilot triple-telescopic lifting gear
is fitted. It is a specially modified unit based on the standard type and known• as the V14, providing a rigid body support without the need for a stabilizer. The top of the rams is level with the body and they do not, therefore. reduce the effective clearance between the body and hopper. The tip angle is 35° and the body can be louvered in 17 sec. The control lever is located in the cab.
The body is braced internally by diagonal and cross-members of steel tubing at the front and rear and a fixed rear panel with a depth of 12 in. is mounted above the tailboard. The floor is of h-in, chequer plate, and a removable 12-in, wearing strip is fitted in front of the tailboard.
The sides of the standard vehicles are of *-in. softwood, panelled in 20-gauge alloy sheet, which are little heavier than those built of tongued-and-grooved, or corrugated, alloy sections. Their use saves about £50. It is also claimed that they have greater strength and are less costly to repair. All-metal light-alloy sides are, however, available if required.
The uprights arc of steel or light alloy, the steel members being welded to the cross-bearers and alloy members bolted. The overall length of the body is 21 ft., but a 20-ft. 'body can be supplied. The sides are 4 ft. 5 in, high and the width is 7 ft.
