Our SH series wire rope hoists come in four frame sizes and lift up to 30 tons. Limited space? Choose a base or underhung mount. Space not a problem? We have top-mounted hoists too. Need to travel as well as lift? A single or double-girder trolley is your solution.
Two-speed hoist and trolley motors are standard. So are magnetic disc brakes; cast-iron rope guides; and virtually maintenance-free, oil-bath lubricated gearing. Safety features include weight overload switches, geared upper/lower limit switches and thermal motor protection.
1. Control Panel - Fiberglass-reinforced NEMA 4X housing. Weld-resistant contactors standard. Hoist motor management unit with hoist and trolley motor temperature control.
2. Wire Rope Guide - Wear-resistant guide constructed from robust, cast steel alloy. Prevents rope from jumping grooves. Maintains tautness during wind-up.
3. Geared Upper and Lower Limit Switch - Mounted in control panel. Cuts off at upper and lower hook position. Switching for additional stops avahlable.
4. Wire Rope Drum - Designed for maximum safety and service life. Drul grooves machined to HMI-recommended depth of 3/8ths of rope diameter.
5. Gear Reducer - Low noise, smooth-running helical gears with lifetime lubrication. Completely enclosed in monobox housing (except SH6).
6. Hoist Motor - Oversized, heavy duty, TEFC design. Two speeds standard for fast lifting, precise handling. Duty cycles up to 60% (time on vs. off). Power ratings to 49 HP.
7. Hoist Brake - Dual disc, totally enclosed, magnetic brake. Oversized for safety. Self-adjusting. Dustproof.
8. Weight Overload Device (optional) - Safety limit switch activates when hoist is overloaded.
9. Thermal Motor Protection - Standard for hoist and trolley motors.
10. Wire Rope and Load Hook - High strength, flexible wire ropes. Safety factor of 5.0 or better. Longlift hoists have non-rotating ropes. Forged, oversized load hooks. Low profile to maximize headroom. Hooks swivel, have spring-loaded safety latch. |
