Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of crane parts, and specifically relates to a hoisting device of a truck crane. BACKGROUND

[0002] The crane refers to the multi-action hoisting machinery for vertically lifting and horizontally transporting heavy objects within a certain range. It is also known as a crown block, a crane, a hoist, and a tire crane. The main features of the tire crane are that the traveling cab and the hoisting control room are combined into one, and the track and the walking support part of the track crane are changed into a chassis with tires. This overcomes the disadvantage of the track crane (track crane) that the track plate damages the road surface. It belongs to the material handling machinery. The bridge crane is a hoisting device for hoisting materials above the workshop, warehouse and material yard. Because its two ends are located on high cement columns or metal supports, it looks like a bridge. The bridge of the bridge crane runs longitudinally along the track laid on the high rack on both sides. It can fully utilize the space below the bridge for hoisting materials and is not hindered by ground equipment. It is the most widely used and largest number of hoisting machinery. The hoisting equipment has the characteristics of intermittent motion, that is, in a working cycle, the corresponding mechanisms for taking material, moving, and unloading are alternately operated. The crane is developing and being used more and more widely in the market. Some accidents often occur when the crane is not supported by the legs and is hoisting and traveling. The traveling speed is faster than that of the track crane (track crane). The operation is stable, the hoisting capacity is large, the crane can travel with the load within a certain range, but the road must be flat and solid, the tire pressure must meet the requirements, and the lifting distance from the ground must not exceed 50 cm. It is prohibited to travel with load for a long distance. In order to ensure the safety of operation, it is basically prohibited to carry out hoisting operation without supporting legs in China. The steel wire rope used with the crane includes phosphating coated steel wire rope, galvanized steel wire rope and smooth steel wire rope.
