Triple reduction hoist gearing is oil bathlubricated, operating in an oil-tight, cast aluminum gear case. The gear case 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 6:1 ratio from high to low speed; give a low speed for precise load handling and a high speed for fast throughput.
Wire rope drum and rope guide
The wire rope drum is machined from quality steel, deep-grooved with a rope guide to help ensure the rope stays in the grooves.
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).
Trunnion style block and hook
Each hoist comes with a bearing nounted trunnion hook that rotates 360 and swings back and forth 180 for easier load adjustment.
Upper/lower geared limit switch
The hoist is provided with an upper/lower, geared control circuit hoist motion limit switch as standard. An additional bloack-operated upper control circuit limit switch is available as an option.
Hoist overcapacity limit switch
A hoist overcapacity limit switch is provided as standard to prevent lifting excessive overloads.
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 somooth starting andstopping.
Hoist and trolley controls are hoiused in a common IP54 enclosed with the following features as standard:
Motor line fusing
Fused control circuit transformer
Hoist motion monitor
Motor thermal overloads
Hoist over capacity limit switch
All components are of the highest quality and the panel design meets EN and IEC.
