Definition of large mechanical equipment?
The hoisting machinery used in bridge construction can be divided into three categories: light and small lifting equipment, bridge type crane and boom type crane. Light and small lifting equipment, such as jacks, hoists, winches, etc.. Bridge type lifting machinery, such as beam cranes, Longmen cranes and so on. Boom type cranes, such as stationary slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc..
Usually, crane hoisting (make things up and down movement), operation mechanism (the mobile crane), luffing mechanism and slewing mechanism (the horizontal movement of goods), plus metal mechanism, driving device, control device and the necessary auxiliary assembly.
A crane is a machine that cycles and intermittently moves. A work cycle includes fetching device from the extract to bring up the product, then move to the designated place down items, then reverse movement, the fetching device back in, for the next cycle.
Depending on the size of the part to be machined, the parts must be set up as large equipment with the aid of a crane, and large machinery is usually assembled after the parts have been delivered to the destination. Material handling machinery is mainly in enterprises (including terminals, materials, mines and commercial warehouses, etc.) within the material handling, transportation, lifting, stacking and storage of machinery and equipment
