(54) CARGO HANDLING DEVICE

The invention relates to lifting equipment, in particular, load handling devices.

A load gripping device is known, which comprises a boot case hung by means of a staple on a hook of a lifting mechanism, a spring-loaded load lever and a spring-loaded lock 1J,

However, such a device is not reliable in operation, since the lock is not protected from impacts on surrounding objects.

The chain of the invention is to increase the reliability of the device in operation.

The delivered chain is achieved by having the lock pivotally secured in the housing and made & as a two-shouldered lever with protrusions at the ends and in the middle part, and the cargo lever is also hinged in the case and made V-shape M5 interacting with the seizure of cargo with one shoulder with a protrusion in the middle part of the two-arm lever, and the other with a protrusion

at one end of this lever, with the bracket installed in the housing with the possibility of its vertical movement and constant contact with the protrusion at the other end of the two shoulders.

FIG. 1 shows a gripping device, a slit; in fig. 2 — load-gripping device at the moment of engagement of the load-bearing ring; in fig. 3 - gripping device. At the moment of lifting the load.

The load gripping device contains a hollow body 1, inside of which cargo lever 3 is mounted on axis 2 and clamp 5 is mounted on axis 4. In the upper part of cargo lever 3 there is a spring 5 at 6. Clamp 5 It is designed as a double arm with a protrusion 7 at one end, the protrusion 8 - in the middle part and the protrusion 9 - on the other end. At the top of the latch 5 is installed

0 spring-loaded pin 10, interacting with the inner surface of the housing 1. In the housing in its upper part there is an oval hole 11, in which the bracket 12 is mounted for vertical movement, having to be locked in contact with the protrusion 7 of the retainer 5. The load lever 3 is designed as a V-shaped a lever with the shoulders 13 and 14 interacting with the latch 5. In the lower part of the body, a slot 15 is made for inserting a load of a load ring 16. The device works as follows. The device is suspended on the lifting mechanism by the bracket 12, the load-carrying colado 16 is inserted into the slot 15 of the housing 1. While the load-carrying ring 16 presses on the shoulder 13 of the loads of the th lever 3 {Fig. 1) and rotates it around axis 2 until arm 13 engages with vyoupu 8 clamp 5 (Fig. 2). With this, the bracket 12 is located in the lower part of the opening 11 of the body I. When lifting the load, the bracket 12 moves into. the upper part of the hole 11 and rotates the latch 5 Around the axis 4, As a result, the shoulder 13 of the cargo lever 3 slides off the protrusion 8, and the shoulder 14 of the lever is resting on | the protrusion 9 is fixed at 5 (fig. 3). When the load is lowered, the tension of the bracket 12 weakens, the latch 5 is rotated with the action of the spring-loaded pin Yu, and the protrusion 9 comes out of the interlock
