Ingersoll Rand ML1000KS-1B15-B11S MLK Series Air Chain Hoist is a slow-speed spotting pneumatic hoist engineered for applications requiring exceptional precision during lifting and positioning. With a 1 Ton (2,200 lb) lifting capacity, 15 ft lift, and 11 ft pull chain control drop, this model is well suited for machinery installation, equipment maintenance, precision assembly, and production operations where careful load placement is essential. The manual pull chain control allows the operator to actuate the hoist directly without a pendant station.
Built on the proven MLK Series platform, the ML1000KS utilizes a reduced lifting speed for improved spotting accuracy while maintaining a 100% duty cycle for continuous industrial service. Its self-adjusting air-operated disc brake, enclosed planetary gearing, anti-friction bearings, and modular internal components help deliver reliable operation while simplifying routine maintenance. This model is equipped with Bullard self-closing hooks for enhanced load retention during lifting operations.
