Description

The constructions of the lifts are known, which are a vertical pivot bar, which carries the swing: boom with a cargo arm, suspended in such a way that the bottom of it at any angle of the junction; remains threefold. However, their disadvantage is that they are mounted on a truck platform. and require the use of outsidershters, which, in turn, reduces maneuverability and complicates the design of the lift.

In the described construction, this drawback is eliminated due to the fact that the lift is a detachable attachment to the forklift truck and is made in the form of a frame, in bearings of which a boom with a cargo area is fitted with a vertical bar, the rotation of which is mounted on the frame 1 hydrodil.

The drawing shows a lift.

The lift consists of a frame /, represented by the hinged equipment to an automobile loader, in a radial bearing 2 slide and supporting axle rolling 3 which has a vertical rod 4 carrying a folding boom 5 with a cargo platform 6. Lifting boom 5 is carried out by a hydraulic rail 7 mounted on the rod 4 and connected by a chain 8 with a drum P fastened to the boom 5. The rod 4 in the bearings 2 and 3 of the frame is rotated / carried out by the hydraulic cylinder 10 mounted on the frame /. The bottom of the loading platform 6 remains horizontal at any angle of inclination of the boom 5 due to the presence of two fixed rollers // fixed on the rod 4 and two rotating rollers 12 mounted on the platform 6. Both pairs of rollers are connected by a link /, so that when the boom 5 deviates at any angle pad 6 deviates

at the same angle, but in the opposite direction. In order to ensure safe lowering of the cargo platform 6 when the oil supply of the hose / 4 is disconnected, a hydrazal / hydraulic damper / 5 is integrated into the gyro-hydraulics 7.

PRIOR DIRECTORSHIP and

1. The elevator, which is a vertical pivot grip bearing a swinging boom with a cargo platform, is suspended in such a way that the bottom of the boom remains horizontal at any angle of inclination of the boom: the possibility of using it as a removable attachment to a forklift truck, a crawler lift in the form of a frame, B, under support. Which is equipped with a vertical boom with a loading platform with a hydraulic cylinder mounted on the frame.

2. The form of the elevator but p. 1, characterized in that, with the aim to: safe cargo cargo at 1) the oil supply slag, into the hydraulic line Estroene hydraulic damper.
