A guide assembly in a material-handling device (10) is disclosed which includes a frame (18), a mast assembly (12) pivotally mounted adjacent its bottom end (16) to the frame, and hydraulic cylinders (20) for rotating the mast assembly to tilt forwardly and rearwardly. The assembly further includes a bar (22) attached to the frame spaced from the mast assembly. The assembly also includes a guide tongue (29) pivotally mounted to said mast assembly further above the bottom end thereof than is the pivotal mounting thereof to the frame (18) and slidingly disposed intermediate its ends to the guide bar (22). The hydraulic cylinders are positioned to act between the frame (18) and the tongue (29).

This invention relates to a self adjusting bearing arrrangement (10) for a pair of relatively movably members (12) which eliminates the problems of manual adjustment, improper adjustment, premature bearing failure and inefficient operation of the relatively movable members (12). The self adjusting bearing arrangement (10) has a bearing (17) slidably guided by a support assembly (28) connected to the first member (18) and a thrust member (32) movable relative to the bearing (17) for applying a predetermined force to the bearing (17) and moving the bearing (17) from a first position at which the bearing (17) is spaced from contact with the second member 20 and a second position at which the bearing (17) is in contact with the second member (20) and for maintaining the bearing (17) at the second position. Thus, the self adjusting bearing arrangement eliminates the problems of manual adjustment, improve adjustment, premature bearing failure and inefficient operation of the relatively movable members (12). The self adjusting bearing arrangement is particularly useful in a lift mast assembly.

A material handling vehicle has a generally vertically movable carriage, first and second spaced apart, chain assemblies connected to the carriage, and a power device associated with the chain assemblies for generally vertically moving the first ends of the chain assemblies and the carriage in response thereto. A pivot element is associated with the chain assemblies for controlling relative movement thereof.

A container handling attachment is provided for lift trucks and the like to permit such trucks to load and transport relatively large horizontally disposed cylindrical objects. The attachment includes a pair of sleeve members which are slidably received over the forks of a conventional lift mast to permit easy attachment thereto. The attachment also includes a pair of lifting lugs which are selectively positionable in underlying engagement with a pair of longitudinally spaced lifting bars provided on the object. Latching means are positionable around such lifting bars to prevent their disengagement from the lifting lugs. Bumper stops are also provided for engagement with the legs of the object to prevent rotation of the object about its longitudinal axis when it is raised from the ground.
