Regarding large-scale lifting machinery
Thread Content
I would like to ask everyone: what is the definition of large-scale lifting equipment, or in which specifications or documents is it described?
There are four crane rental company ads under your post; ask them
It generally refers to large crawler cranes, truck cranes with truss arms, and all-terrain hydraulic truck cranes. The term “large” is defined differently by various industries or corporate groups; for example, CNPC defines it as 350 tons or more.
For projects under construction that require a weight of 50 tons or more (but not including 50 tons), it is necessary to first determine the weight of the equipment, its height, the distance to the lifting site, as well as any obstacles in the vicinity. The lifting company is determined through bidding. There are two forms of lifting costs: 1. All-inclusive cost. 2. Daily shift cost for cranes of various tonnages.
