Double Girder EOT Crane Parts
Double Girder EOT Crane Parts
Description
Double Girder EOT (Electric Overhead Travelling) Crane Parts refer to the individual mechanical, structural, and electrical components that come together to form a high-capacity material handling crane used in industrial settings. In a double girder configuration, two parallel girders support a crab-mounted hoisting mechanism, which moves across the bridge to lift and carry heavy loads efficiently.
These parts are designed for durability, precision, and performance under high-load conditions — typically in heavy engineering, manufacturing, steel, cement, and logistics industries.
How It’s Made
Each part of a double girder EOT crane is engineered with precision and tested for safety and load performance:
-
Girders:
Fabricated using high-strength mild steel plates through welding or box-type construction. The girders are stress-relieved and machined for alignment. -
End Carriages:
Made from steel channels or plates, mounted with wheels and bearings. These provide horizontal movement across the gantry rails. -
Crab Assembly:
A separate trolley unit consisting of hoist, motor, gearbox, and brakes — designed for cross travel between the girders. -
Hoisting Mechanism:
Consists of electric hoist, rope drum, wire rope, sheaves, and hook block. Built with hardened steel and alloy components. -
Motors & Gearboxes:
Squirrel cage induction motors with brake systems, coupled with helical or planetary gearboxes for travel and lifting motion. -
Control Panel & Wiring:
Includes contactors, limit switches, overload protection, and VFD (if required). Housed in dust-proof enclosures. -
Brakes & Couplings:
Electromagnetic or hydraulic thruster brakes provide instant stopping power. Flexible couplings absorb shock loads. -
Electrical Festoon System or Cable Trolley:
Provides power to the hoist and trolley through flexible trailing cables. Paint & Surface Treatment:
Anti-corrosive primer and industrial-grade paint applied to protect from harsh environments.
