ABSTRACT:
An off-highway dump vehicle of the bottom-dump, two axle type having a single wheel in all positions; an A-frame front suspension which provides large steering angles for the vehicle wheels; an A-frame rear suspension system separate from the front suspension system; a dual braking system comprising primary and secondary brakes actuated by a common brake pedal and arranged wherein the secondary brakes are automatically actuated upon failure of the primary brakes for any reason; the vehicle structural elements being pinned together for facilitating assembly and disassembly thereof for shipment of the vehicle to the site of operation thereof; the vehicle load in the rear is carried directly on torque tubes and the front load is cantilevered from the torque tubes; the vehicle deck is a "floating" type structure in that the only elements carried by the deck are the fluid lines for the braking system, steering system, and the like; the access door to the axle box is of a self-closing construction in that air pressure differential across the door urges the door toward a closed position and keeps it closed; the vehicle transmission is of the automatic type which includes a "park" position, and the vehicle is provided with a front engine and rear wheel drive.
