Electric Wire Rope Hoist vs Chain Hoist: Technical Comparison & Selection
Understand the mechanical differences between electric wire rope hoists and chain hoists to select the correct unit for ...
Where factory buildings lack overhead runway columns, or where materials must be stacked and shifted in open outdoor yards, Gantry Cranes and Goliath Cranes provide the ultimate heavy-lifting solution. Supported by rigid structural legs travelling on ground-level rails, gantry cranes handle capacities ranging from 1 Ton to 150 Tons.
Outdoor Engineering Considerations
Unlike indoor bridge cranes, outdoor gantry and goliath cranes are subjected to severe atmospheric and wind stresses. Reliable manufacturers must incorporate:
- IS 875 Wind Code Calculations: Rigid box-girder or tubular A-frame legs engineered to withstand maximum regional wind velocity.
- Mechanical Storm Anchors & Rail Clamps: Hydraulic or manual rail clamps that lock the crane securely during storm warnings.
- Cantilever Extensions: Single or double overhangs allowing the hoist crab to travel outside the rail track to load directly onto road trailers or railway wagons.
- Weather Enclosures: IP55/IP65 weather hoods protecting hoist motors, thruster brakes, and electrical VFD panels.
Leading Manufacturers in India
India's leading builders of outdoor gantry infrastructure include Ganesh Engineering Co. (Ahmedabad), Anupam Industries, and ElectroMech. Ganesh Engineering designs single girder gantry cranes (1-20T), heavy double girder goliath cranes (10-150T), and semi-gantry cranes tailored to site civil drawings.
