Abstract

A load tilting attachment for an industrial truck having an upstanding mast and a carriage vertically movable on the mast, said attachment including: a vertically disposed stationary plate secured to the carriage, the plate having a bearing for supporting a load on the carriage through the plate, and load reaction members radially spaced from the bearing; a vertically disposed body aligned with the plate, the body having secured to one face thereof a pivot spindle projecting from the body into and pivotable on the bearing, and second load reaction members on said one face radially disposed from said spindle movable on and cooperating with the plate reaction members; a piston-cylinder assembly connecting the plate and body for pivoting the spindle on the bearing and moving the body reaction members relative to the plate reaction members to tilt the body on the plate; and a load supporting member on the body. The attachment may also include a hydraulically actuated clamp on the body for manipulating the load supporting member to grasp a load.

Dependent claims

In a load tilting attachment for an industrial truck having a vertically movable carriage and load supporting means, said tilting arrangement comprising:

a vertically disposed plate secured to and movable with said carriage, a vertically disposed tilt boy aligned with said plate, means for tilting said body in a limited arc relative to and parallel with said plate, said tilting means consisting of a spindle-bearing assembly centrally of said plate and said body for pivoting said body in a vertically disposed arc, circumferentially spaced load reaction members between said plate and said body and spaced radially from said spindle-bearing assembly for restraining rocking movement of said body relative to said plate, one of said load reaction members comprising an arcuate plate secured to said tilt body above said spindle-bearing assembly and an associated bearing plate secured to said vertically disposed plate and against which said arcuate plate bears, said arcuate plate and said bearing plate being interlocked in a hook-like arrangement to resist outward and axial rocking movement between them under load, means connecting said plate and said body for driving said body about said pivot in said arc, and means connecting said load supporting means to said body.
