LOADER LOAD LIFTER Russian patent published in 2017 - IPC B66F9/08 B66F9/20 

FIELD: transportation.

SUBSTANCE: lifting or lowering the fork (21) are performed by means of switching the engine, which by means of a worm (17) and a worm wheel (16) rotates the drive sprocket (14) of the chain transmission. Wherein the rotation of the driven sprocket (20) on the axis (18) and the movement of the chain (15) together with the truck carriage (19) and the fork (21) fixed by means of the engine shutdown are performed. For the guides (7) deviation from the vertical, the engine is switched on, which rotates the shaft (13) with the worm (12), which through a gear wheel (11) and the worm connected to it (9) rotates the geared wheel (8) with the axis (6) and the guides (7). After the guides deviation to the desired position, they are fixed by means of the engine shutdown. Turning the wheel (2) with the guides (7), the cargo carriage (19) and the fork (21) around the vertical axis is performed by an engine rotating the worm 5 moving the geared wheel (2) on the bushing (3) together with the stands. The fork (21) having reached the desired position on the horizontal plane, said engine is turned off, providing the platform fixation due to the worm gear self-locking.

EFFECT: simplified design, extended functional possibilities and improved operating characteristics.
