Abstract: An articulated forklift truck for use in narrow aisles comprises a front chassis section 10 having a first pair of ground-engaging wheels 20 and a rear chassis section 12 having a second pair of ground-engaging wheels 22. The front chassis section 10 carries a mast 16 and lift forks 18 and is pivoted to the rear chassis section 12 about a substantially vertical axis 14 to allow the truck to be steered. All four wheels 20, 22 are driven individually by respective hydrostatic motors 24, 26.

Abstract: A drive controller for a hydraulic drive system, a three wheeled vehicle having a pair of transversely arranged in line of drive shaft assemblies and a single wheel drive shaft assembly each assembly including a drive unit having two separate drives and has for series operation secondary hydraulic feed lines between one of the drives of the single drive units and one of the drives of each transverse drive unit. A pressure release valve is provided in each secondary line which valve is fed through a non-return valve.

Abstract: A hydraulic drive system incorporating a hydraulic pump for three wheeled vehicles such as “piggy back” forklifts in which there are at least two separate but linked drives forming one drive unit for each of the wheels and each drive has a separate input and output. Valving is provided to provide both parallel and series operation of the system for optimum torque, speed and anti skid operation. In one preferred way of carrying out the invention a single drive unit feeds one of the drives of each of the other drives. The hydraulic pump feeds the single drive unit and one of the drives of the other transverse drive units. By-pass diverter valves are fitted across the drives of the transverse drive units.

Abstract: A crash bar assembly for a vehicle having an auxiliary equipment carrying mode with, for example, a forklift extending beyond its rearmost portion. The impact absorbing bar forming part of the assembly is movable outwardly to adjacent the rearmost end of the forklift on bars in sockets. A forklift may have a crash bar assembly mounted on itself.

Abstract: A universal forklift truck mounting frame (1) for fitting at a rear end of a carrier vehicle chassis has a composite base support framework. The base support framework has a rear support beam (8) and a front support beam (20) interconnected by a pair of spaced-apart hanger plates (5). Each hanger plate (5) has a flanged upper end (6) to provide a laterally extending chassis engaging surface. A wheel rest plate (9) is mounted at each end of the rear support beam (8). A pair of fork support sleeves (18), each for engagement with a fork of a forklift truck are mounted on the support framework between and substantially parallel to the hanger plates (5). A crash bar (10) is mounted at a rear end of the hanger plates (5).
