Economy Wire Rope Crab
1. Hoisting Motor
Highly efficiently squirrel cage motors which especially designed for hoist are applied and comply with IEC specification with insulation F degree and start torque over 200%.
2. Electromagnetic Disc Type Dual DC Brake
Use electromagnetic disc type brake of Lenze, the biggest supplier in Germany, to perform the brake torque over 250% with durable wear-resisting, long life, rapid reaction, low noise and convenient for maintenance.
Apply alloy steel as base materials of gears with hardness higher than HRC 50 degree and oil bath lubrication of gears for long lifespan.
Apply qualified high-strength steel.
5. Screw Type Up/Down Limit Switch
Apply principle of screw rotation to set up/ down limit and terminal limit to avoid crab damage for wrong direction.
Only junction box left on the crab.
Prevent wire rope loose and out of grooves.
8.Transmission of Traversing
a)Soft Start/Stop Reduction Gear Motor:
Utilize of flywheel inertia, the motor works very smoothly when it starts and stops.
b)Hollow shaft gear reducer motor:
Integrated motor, brake and gear box for easy fabrication and maintenance.
9. Wire Rope
Safety factor complies with FEM requirements. Dual rope designs for bottom hook stable and easy hanging.
10. Bottom Hook Set
Hooks are made by forged steel with proper diameter of reeving wheel to ensure life span of wire rope.
Control panel sets on the walkway.
12.Anti-sway (Optional Function)
Anti-sway for traversing and travelling corrects swing motion during operation.
