2. Wire Rope
- Wound from high strength metal strands designed for long life and low wear
- Available designs: steel, stainless steel for corrosion resistance, and rotation resistant
- Minimum of 5:1 safety factor of all wire ropes
- Electrolift chooses the type of wire rope for each hoist based on specific application
3. Wire Rope Drum
- Spools and unspools wire rope on helical groove to lift or lower load blocks
- Helical grooves on drum prevent the wire rope from overwrapping
- At least 2 dead wraps remain on the drum when the rope is unwound during normal operation
- Drum/rope diameter is optimized to reduce rope flex, reducing wear and extending rope life
- Special features available:
- Deep grooving
- Rope guide
- Quick disconnect wire rope dead-ending
4. Drum Shaft
- Transmits torque from the gear reducer to wire rope drum
- Fabricated from high strength, cold-rolled steel
- Designed for infinite life
- High overload capacity
5. Motor
- Standard motor is 3 phase, Nema class D, 30-minute duty, class H
- Voltages available: 230/460V standard, 208V, 575V
- Electrolift offers optional 60-minute, continuous duty, and inverter duty motors for heavy-duty service
- Standard motors contain thermal switches to protect from overloading the motor
6. Motor Brake
