A lift truck 100 has an inertial damper 150 coupled between the base frame 116 and a A-frame holding a suspended wheel. The damper has a slider plate 170 frictionally engaged by friction pads 161, 169 on outer plate 160 and friction pads 181, 189 on the other outer plate 180. The outer plates 160, 180 are spring biased against slider plate 170 by belville washers 162, 182 or a coil spring 210.

Control handle for a material handling vehicle

In a lift truck having one steerable powered drive wheel assembly and a steerable idler wheel assembly interconnected by a pair of links and a crank, steering is accomplished by means which apply torque directly to the drive wheel assembly. The steering rotation of the drive wheel assembly rotates the idler wheel assembly, so that forces transmitted through the links and the crank to steer the idler wheel assembly are independent of drive wheel loading, and less motive force is required to steer the truck at large cramp angles.

Lift truck steering apparatus

Method and apparatus for storing and retrieving loads increases usable warehouse storage space by allowing a load having a given length and width to be stored and retrieved from a narrow aisle while requiring less wasted space between adjacent stored loads. As a load is rotated 90.degree. preparatory to translating it into a storage space, the center of rotation is moved first in one direction along the aisle and then in the opposite direction. One corner of the load enters and sweeps across the initially empty storage space, and during a terminal portion of the rotation another corner of the load enters the storage space along a path having little or no component of motion in the aisle direction.

Load handling method and apparatus

Provision of an auxiliary mast which is tiltable, as well as being laterally shiftable and rotatable about a vertical axis, allows loads to be handled without the top of the mast damaging previously-stored loads or limiting fork entrance into a storage rack.
