The study of the deviations of the payload moved along the curved trajectory by the crawler crane
Abstract Reducing the uncontrolled deviations of the payload moved by a crawler crane with a constant boom length is a relevant objective, since it improves the operational efficiency and safety, as well as the positional accuracy of the payload at the target point.

Radius survey of crawler crane base on total station
Abstract The process of surveying crane parameters has been continually refined due to the competitive situation, modern surveying instruments and more powerful softwares. As the radius is the crucial parameter to determine the jib crane’s safety, a survey scheme is put forward to solve the problem that the rotary axis can’t be ...

The Secondary Lifting Performance of Crawler Crane Under Delay Coefficient Control Strategy
Crawler cranes are mobile lifting equipment used in the process of hoisting goods. After the initial lifting, the crane may need a secondary lift due to adjustments in the position or height of the load.

Multi-skeleton model for top-down design of complex products
Generally, there are two alternative design approaches available to engineers: bottom-up and top-down. Considering the sharp increase in the complexity of most mechanical products, the top-down design approach is more widely adopted in the development of
