Heavy cargo transportation What are the common lifting methods? Do you understand?
according to Huai'an Crane Rental Many years of hoisting experience has concluded that at present, domestic equipment hoisting enterprises will adopt some common hoisting methods when carrying out the transportation and installation of large equipment, mainly including the following categories.
Unconventional lifting: The hoisting of large pieces of unconventional equipment includes helicopter hoisting, mast hoisting, tower crane hoisting, etc.
Single truck hoisting: Large equipment in Zhengzhou is heavy, so if a single crane is used for lifting, most of them will use crawler cranes with a rated lifting capacity of more than 50 tons. Crawler crane is widely used in heavy lifting because of its stable chassis and large lifting capacity. Large piece handling 。
Double machine lifting bar: Double crane lifting bar is also called double crane lifting bar. Generally, two crawler cranes are used to lift at different lifting points. Double machine lifting bars are mostly used for equipment with large weight, which exceeds the load of single machine. Or the shape of the equipment is strange, so it is convenient to use two cranes for hoisting. Large piece handling.
Hoisting by bridge crane: The bridge crane belongs to a kind of fixed crane. It is characterized by large lifting weight and stable operation. However, most of its early installation is complex, so it is mostly used for port container hoisting.
Hydraulic lifting: The operation of hydraulic lifting for heavy lifting is complex, and the systems to be used include steel strand suspension bearing, hydraulic lifting jack cluster, computer control synchronization, etc.
Ramp lifting: Ramp lifting is also a common lifting method for large pieces in daily operation of Lihang. The ramp is built in front of the equipment, and large equipment can be hoisted to the designated position by using the winch, wheel change set and other tools.
