Many Trolley Benefits from More Standard Features
Harrington RY wire rope hoists are designed and built for today’s heavy-duty wire rope hoist applications including fabricating, die handling, paper mill and production line work. State-of-the-art design features and construction make the RY extremely durable, highly reliable and very low maintenance for years of trouble free service.
The RY includes features that are expensive options on competitive hoists to include standard electromechanical load limiting device, fan-cooled motors and rubber trolley bumpers. Maintenance and failures associated with disc type brakes are eliminated with our revolutionary conical rotor brake system. The sealed hoist electrical enclosure means airborne grit and contamination will not penetrate the hoist to cause premature failure of electrical components. A truly unique wire rope guide prevents improper rope alignment on the grooved drum.
VFD Control – Hoist and Trolley
Soft start/stop minimizes load swing. High and low speed adjustability. Max ratio of 6:1. Includes standard count hour meter that records and displays the number of lifting/lowering starts and hoist on time for preventative maintenance.
Heavy Duty – Fan Cooled Hoist Motor
With class F insulation and a ribbed frame for maximum cooling and durability. IP55 rating ensures a high level of protection from the entrance of dust and water. H4 rated hoist, 60 minute duty rating.
Premium Wire Rope (IWRC, Coated Core)
Provides high resistance to fatigue and wear.
Full 360° Rope Guide
Made of high strength polymer for durability, our rope guide keeps the rope securely in the groove on the drum.
Externally Adjustable Upper/Lower Limit Switches
Set the range of operation with easy adjustment.
Upper Emergency Paddle Limit
Secondary limit independent of drum rotation to comply with US Safety Standard ASME B30.
High Performance Motor Brakes
The pull-rotor motor brake on 3 & 5 Ton models, and a magnetic disc brake on 7.5 and 10 Ton models. Both brakes provide reliable and safe operation and exceptional durability.
Rope Drum
Deep grooved, high strength drum for durability and long service life.
No Load High Speed Function
Operates at 1.5 times the standard high speed with a load less than 25% of rated capacity.
Standard Guide Rollers and Rubber Trolley Bumpers
Guide rollers reduce wheel friction and noise while providing smooth travel and increased life of wheel and beam. Rubber trolley bumpers provide protection from collisions.
Externally Adjustable Trolley Motor and Brake
IP55 totally enclosed non ventilated (TENV) motor with cooling fins ensures protection from dust and water and enhances motor life.
