Acco WRIGHT® Work-Rated® Wire Rope Hoists

High Volume Handling of Heavy Loads

Acco Wright® Work-Rated® hoists are duty service classification H4. Hoists in this category are capable of high volume handling of heavy loads. Operating 30 minutes of each hour with a maximum of 300 starts an hour. Wright® Work-Rated® hoists meet ASME-4M, both mechanically and electrically.

Mechanical Load Brake

Automatic Weston-Type multiple disc brake can hold a full capacity load independent of the motor brake and assures that the load does not accelerate while being lowered. Adjustment is not required.

Motor

The New Century Series utilizes a U.S. manufactured motor, 30-minute
duty, Class F insulation. Standard single speed motor is provided for 208V,
230V/460V or 575V 3 phase, 60 hertz power supplies. Motor thermostats
are standard, providing both running and overcurrent protection.

BEARINGS - SPIDER RETAINER

Precision heavy-duty ball bearings support all shafts. Bearings at outboard end of shafts are held in place by a heavy-duty Spider Retainer. This allows removal of Gear Housing Cover for inspection (after draining oil). All internal parts remain in place and can be operated for inspection.

Motor Brake

Proven in millions of hours of in-service operation, the original Wright® rectified D-C magnet-actuated disc brake delivers rapid stops with virtually no hook drift. Rated a minimum of 150% of full load motor torque. Exclusive brake-sensing microswitch prevents motor from operating against engaged brake and when brake requires adjustment.
