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.
CAPACITY
- 2 – 20 Ton
STANDARDS
- NFPA 70 “National Electric Code”
- ASME B30.16, “Safety Standard – Overhead Hoists (Underhung)”
- ASME HST-4, “Performance Standard for Overhead Electric Wire Rope Hoists”
BODY
- Standard headroom configuration
ROPE SYSTEM
- Premium grade provides high resistance to fatigue and wear
- Spring-tensioned rope guide keeps the rope securely in the grooves on the drum
HOOK
- High strength forged steel
- Capable of swiveling 360 degrees under load
- Top and bottom hooks have heavy-duty hook latch
- Machined carbon steel bottom block sheaves
OPERATION
- Triple reduction helical gearing for smooth, quiet operation with minimum vibration
- Electro-Mechanical load limiter prevents lifting of over capacity loads
- External limit switches protect against hook overtravel
BRAKE
- Conical rotor brake virtually eliminates brake issues
- 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
- Two driven wheels offer better traction for improved operator control
- Driven wheels on opposite sides of the trolley provide smoother operation with less racking and skewing
HEAVY-DUTY TROLLEY DRIVE
- Fan-cooled TEFC drive motor provides long, trouble-free service
- IP55-rated, suitable for outdoor service and adds extra protection for indoor applications
- Helical gear drives in oil bath provides cool, quiet and smooth operation
- Trolley motor design provides smooth acceleration
OPTIONS
- Pendant
- Pendant cord
- Power supply cord
- Trolley travel limit switch
- Block operated limit switch
