設置

Crane is a multi-action lifting machine that lifts heavy objects vertically and horizontally in a certain range. Also known as crane, aerial crane, crane.
The main characteristics of a tyre crane are that the driving cab and the crane control room are combined into one, which is evolved from a crawler crane (crawler crane). The crawler and the traveling bracket of the traveling mechanism are transformed into a chassis with tyres, which overcomes the disadvantage of the crawler crane (crawler crane) crawler board destroying the road surface and belongs to the material handling machinery.
Bridge crane is a lifting equipment which is horizontally mounted over workshop, warehouse and material yard for material hoisting. Because its two ends are situated on tall cement columns or metal brackets, they are shaped like bridges. The bridge of bridge crane runs longitudinally along the rails laid on both sides of the viaduct. It can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of lifting machinery.
Some working characteristics of lifting equipment are intermittent movement, that is to say, the corresponding mechanism of taking, transporting, unloading and other actions in a working cycle works alternately. Cranes are developing and using more and more widely in the market. Because there are often some accidents when driving without leg lifting and lifting weights, and the speed is faster than that of crawler crane (crawler crane); the operation is stable, the lifting weight is large, and the crane can walk in a specific range, but the road must be smooth and solid, the tire pressure meets the requirements, and the lifting distance from the ground must not exceed 50CM; it is forbidden to walk with load for a long distance. In order to ensure the safety of operation, it is basically forbidden to hoist without legs in China at present. Varieties of steel wire ropes used for cranes include phosphating coated steel wire rope, galvanized steel wire rope and smooth steel wire rope.
