Cranes are multiple action lifting machines that lift and carry weights vertically within a certain range. Also known as the crane, hang-hang, crane.
The main characteristics of the tyre crane are: its driving cab and lifting control room, is a crawler crane (crawler crane) evolved, the walking mechanism of the caterpillar and walking bracket part into a tire chassis, to overcome the crawler crane (crawler crane) Crawler board damage to the road surface defects, belonging to material handling machinery.
The bridge crane is the hoisting equipment which carries on the material hoisting in the workshop, the storehouse and the material field. As it sits at both ends of the tall cement column or metal bracket, it is shaped like a bridge. The bridge Crane's frame is running vertically along the track which is laid on the two sides of the elevated frame, which can make full use of the space lifting material under the bridge frame, and is not hindered by the ground equipment. It is the most widely used, the largest number of lifting machinery.
Lifting equipment Some of the characteristics of the work is to do intermittent movement, that is, in a work cycle to pick material, migration, unloading and other actions of the corresponding institutions are alternating work, cranes in the market development and use more and more widely. There are often accidents due to the need not to lift the legs and heavy lifting. The speed of travel is also faster than crawler cranes (crawler crane), stable operation, large lifting volume, can be hung in a specific range of walking, but must ensure a solid road, tire pressure meet the requirements, hanging from the ground should not exceed 50CM; In order to ensure the safety of operations, the current domestic basically prohibit the lifting of the leg to carry out operations. Cranes supporting the use of wire rope varieties include phosphating coated steel wire rope, galvanized steel wire rope and smooth wire rope.
