 Standard
Features
Basic Controls
Choose single or two speed. Magnetic reversing
contactors, both mechanically and electrically
interlocked. 115V control circuit. Meets NEC
requirements. NEMA Type 3R enclosure. Lightweight,
durable, and easily accessible.
Motor Brake
Proven in millions of hours of in-service operation,
the original Wright A-C magnet-actuated disc brake
delivers rapid stops with virtually no hook drift.
Rated a minimum of 150% of full load motor torque.
Motor
The New Century Series utilizes a U.S. manufactured
motor. 30-minute duty, Class F insulation. Standard
single speed motor is provided for 200V, 230V/460V
or 575V 3 phase, 60 hertz power supplies. Motor
thermostats are standard - providing both running
and overcurrent protection.
Drum
Has machined grooves and large flanges for smooth
winding and extended rope life. At least two full
turns of rope remain on the drum at the lowest hook
position.
Limit Switch
A gravity type upper hook travel limit switch comes
equipped with an automatic momentary lowering
circuit.
Lubrication
Gears operate in the largest oil reservoir in the
industry and are enclosed in a rugged fluted
aluminum alloy housing to provide rapid heat
dissipation. Oil sight gauge on the housing cover
permits quick visual inspection.
Mechanical Load
Brake
Automatic Weston-Type multiple disc brake. It 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.
Gear Train
Quiet, helical and spur gearing. All gears are
machine cut, case-hardened alloy steel with
shock-resistant ductile cores. Designed to AGMA
standards.
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.
Wire Rope
Pre-formed wire rope, of hoisting service
construction, has swaged fittings on both ends for
ease of replacement if necessary.
Load Block -
Hook
Drop forged heat-treated steel hook swivels 360° on
a shielded roller thrust bearing and comes equipped
with a spring latch. Work can be performed on the
load block without removing wire rope from drum.
Steel sheaves are standard.
Optional
Overload Cutoff
Protects load, hoist and operator by interrupting
raising circuit when hoist senses a damaging
overload. When lifting circuit is interrupted, the
lowering circuit remains intact to allow the load to
be lowered and removed. After the overload is
removed the lifting circuit is automatically
restored. Overload Cutoff is accessible for field
adjustments.
