L Electric Trolley Gantry Crane

OVERVIEW

The electric trolley gantry crane is a mid –light type gantry crane, equipped with electric and crane hooks, with the obvious features of “ L” shape legs, which makes the crane more convenient for handling cargo with long length, such as, steel pipe, etc. The lifting capacity of the electric trolley gantry crane is 5 to 32 ton and working class is A5 and A6.

Components of Electric Trolley Gantry Crane

Electric trolley gantry crane is mainly consisted of bridge, L shape support leg, crane travelling system, electric trolley, and electric system, etc.

Electric trolley gantry crane is the optimal choice for outdoor material handling for the applications where no supporting building or steel work is available or the supporting building is not suitable for supporting overhead crane. 

They are widely used in cement plant, construction, electronics industries, warehouses, railway, food, papermaking, engineering industry, etc. However, it is prohibited to be used in dangerous environments, such as, high temperature, flammable, explosive, corrosion and other environment, etc.
