After years of development, the crane business of Shandong Great Wall Crane Machinery Co., Ltd. has covered all parts of the country, and has set up crane business offices in many places. New and old customers are welcome to consult and negotiate.
A crane is a multi-action lifting machine that vertically lifts and carries heavy loads horizontally within a certain range. It is also called overhead crane, aerial crane, crane.
Overhead cranes are lifting equipment for lifting materials horizontally over workshops, warehouses and storage yards. As its ends sit on tall concrete pillars or metal supports, it looks like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is the most widely used and largest number of lifting appliances.
Some of the working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms of material taking, moving, unloading and other actions in a working cycle alternate. The development and use of cranes in the market are becoming more and more widespread. Due to the use of outriggers and cranes, there are often some accidents, and the speed is faster than crawler cranes (crawler cranes); the operation is stable, the lifting capacity is large, and it can be hoisted in a specific range, but the road must be smooth 、 The tire pressure meets the requirements, and the lift must not exceed 50CM from the ground; it is forbidden to walk with a load for a long distance. In order to ensure the safety of operations, lifting operations without supporting legs are basically prohibited in China. The types of steel wire ropes used in cranes include phosphate coated steel wire ropes, galvanized steel wire ropes and smooth wire ropes.
