Definition crane

Crane is mounted on the chassis or regular car on a special crane chassis of the vehicle and its driving cab and lifting separate control room setting.
This crane has the advantage of good mobility shift rapidly . Disadvantage is that when working legs , can not load driving, do not fit in soft or muddy work on site .
Outline
The concept of crane hoists the car and combining forms can not assemble themselves directly to work.
Feature is convenient and flexible, high efficiency, fast transitions , improve work efficiency.
Disadvantage is that the terrain , large equipment ( 1000-2000 t ) can not be completed . ( The world's largest tonnage of 1200 tons truck crane . )
Mainly used in construction .
Such as : roads, bridges, buildings, rescue and more.
General engineering teams, construction, electrical installation sector , need car Pallet stackers .
Works
Inside the boom following a rotating drum , at around the wire rope through the pulley on the top of the arm section , the upper boom section pulled out , and so on. Retracted, reverse recovery rope drum , boom retracted under its own weight . The rotating drum driven by hydraulic motor , so they can see the two tubing, but do not as a cylinder .
In addition there are some telescopic crane mounted inside the suit -type piston cylinder, but this application is extremely rare. Multiple levels of expensive ram cylinder , and the boom will occur under load elastically bent , the cylinder life greatly.
Truck Crane Design Outsourcing
Definition
Crane design outsourcing services : refers to corporate clients to hire a professional truck crane design services provider , provides enterprise customers a full range of technical services CMD to enhance technological advantages, reduce development costs behavior.
Classification
Development of design : application of mature design experience or have a viable new technologies, designing new truck crane , including functional design and mechanical design .
Scalability Design: According to experience and technology development on the existing crane design updates, to improve performance and reduce manufacturing costs or reduce operating costs.
Derivative design : In order to meet new demands on the existing truck crane as part of the modification or deletion , which developed from the standard type of derivative products.
Series design : as the female parent in a truck crane , designed a series of similar shape with the same function , but the power , tonnage , dimensions somewhat different range of products.
