RH Wire Rope Trolley Hoists

Superior Load Positioning

For general use on bridge, gantry or jib cranes, as well as monorails, this standard headroom Harrington monorail style trolley hoist combines versatility and performance.

High Strength Forged Steel Hook

You will get nothing but strength out of this hook and it is able to swivel 360 degrees under load.

Premium Wire Rope

Top quality rope provides resistance to fatigue and wear.

Reliable Conical Rotor Brake

This super reliable conical rotor brake is fan cooled to ensure long life.

  • Fan cooled to ensure long life
MOTOR
  • Hoist and trolley feature a heavy-duty fan cooled (TEFC) motor
  • Class F insulation
  • Includes thermal protection
  • Finned cast aluminum housing for maximum durability
RUBBER BUMPERS
  • Reduce mechanical impact against trolley stops and are required for trolley hoist installation on overhead bridge cranes
DUAL TREAD WHEELS WITH GEAR GUARDS
  • Flat and tapered tread section is ideal for S or W beams
  • Ensures smooth tracking on wide flange beams common in industry
  • Gear guards protect gear ring and flange, as well as personnel
EXTENDED WHEELBASE DESIGN
  • Larger wheelbase than competitive units offers more stable travel
  • Provides better load distribution over the beam to reduce beam loading
DUAL-SIDE TROLLEY DRIVE
