(54) LOADING DEVICE FOR LONG-TERM PACKAGES {{S)

MATERIALS.

The invention relates to load handling devices and can be used in bag handling points. Known lifting devices for transporting metal forms containing the traverse with horizontally movable grippers connected in pairs with ropes pressed in two polyspast l. These devices have a limited stroke of the gripping hooks, due to the length of the locking mechanism, a complex system of driving the grippers, which increases the cycle time for chaining and uncoupling. Rigid fastening of the grippers does not provide a clue of the cargo for flexible ties tightly covering the package of long materials. It is also known lifting device .dl packages of lengthy materials, controlled by ropes double drum winch and containing a hollow box-shaped traverse, suspended pa supporting ropes winch and carrying gripping bodies, interconnected closing cable winch 2, However, these devices can not provide automatic capture and uncoupling packages from long materials tied up with flexible slings. The purpose of the invention is to provide automation of the process of capturing a package of materials and its release. This is achieved by the fact that each; the gripping body is made in the form of a spring-loaded hook installed inside the crosshead with the possibility of moving along it and turning in a vertical plane. Pa figs. 1 shows the device described, in section in FIG. 2 device at the time of the packet capture. The load gripping device comprises a hollow box-like yoke 1 suspended on supporting ropes 2 and 3 of a winch (not shown) and carrying gripping bodies made in the form of hooks 4 and 5 connected by a closing cable 6 of the winch. Each hook is provided with a return spring 7 and is mounted for movement along guides 8 and 9 inside the crosshead. The principle of the device is as follows. Gripping device is hung on supporting ropes worn

on the crane hook (not shown). Rope b is attached to two hooks. The device is then lowered onto the bag in such a way that hooks 4 and 5 are on the outer side of the stacking containers. When turning on the quinoa, which serves to lift the closing rope, the hooks will move along the traverse bars towards each other. Due to the fact that the return spring 7 counteracts the movement of the crush, they turn to a horizontal position. After capturing both staple containers by crocks, the drum is turned on.

lifting support in the ropes.

  --- .; -;

The package, captured by the grab container, is lifted by crane with the help of supporting ropes. After the package has been laid, the grip hangs on the supporting ropes, the closures of the rope are loosened, and the hooks are returned from the spring to the initial position.
