What Are Overhead Cranes?
What is an electric overhead crane?
Overhead cranes are used to lift and move loads from one location to another in an efficient and safe motion. Ususally, the overhead cranes are consisted of one/ two crane girder bridge, two crane runways, and crane hoist trolley which is suspened on the under flange of crane bridge or rides on along the runways on the bridge for loads horizontally and vertically.
Overview of overhead crane
Concept of overhead cranes :This crane is Horizontal placed in workshop, storage, on top of steel support. It used to lift object or machine.
Working Application of overhead cranes :Workshop, factory, warehouse, store yard for loads loading& unloading
Loading capacity of overhead cranes :Rated capacity from 1 ton to 550 ton.
Advantage of overhead cranes : High safety and efficiency which can be customized with with various crane configurations and designs with Light duty, Medium duty and Heavy duty.
Disadvantage of overhead cranes Supporting structure is needed by overhead crane in working area, cost is higher, working area is limited.
Structure of overhead cranes :Overhead cranes are travelling on rail which are placed on concrete or steel structure.
