Features
Block operated limit switch - The hoist is provided with a block actuated
upper limit switch, meeting the requirements of A.S.M.E. The limit switch
is actuated by contact with the lower block, preventing double blocking, possible
rope breakage and load drop. Also included is an upper and lower geared limit
switch.
Hoist gearcase and motor - Triple reduction hoist gearing is oil bath lubricated,
operating in an oil-tight, vacuum cast aluminum gear case. The gearcase is
conveniently located to allow ease of access in the air, while providing a
low headroom design with maximum lift. The motor is two-speed with a 4:1 ratio
from high to low speed; giving a low speed for precise load handling and a
high speed for fast throughput.
Wire rope drum and wire rope guide - The wire rope drum is machined from
quality steel, grooved to a depth equal to 20% of the rope’s diameter,
with a rope guide to help ensure the rope stays in the grooves.
Trolley traverse drive - Two wheels are driven; one on each side of the
frame for maximum traction and uniform tracking. Traverse motor drives a right
angle worm gear reducer for smooth starting and stopping (within O.S.H.A.
required distances) without requiring a brake. Trolley traverse drive pinion
shaft is hex-sided; keys not needed for reducer or pinion connections. Each
drive pinion is held in place with locking collars to prevent pinion walking.
Control panel - Hoist and trolley controls are housed in a common NEMA 4/12
control enclosure with generous space for ease of inspection and service.
Controls use only the highest quality components and are designed to meet
NEC standards for maximum life and easy service.
Drum reeving and lower block - Hoist is reeved to a low-headroom design
lower block for minimum headroom and maximum lift. Wire rope is secured to
the drum with three heavy ductile iron clamps and designed to have three extra
wraps of wire rope on the drum with the rope at full extension (low hook).
