Designed for continuous lifting in manufacturing, maintenance, fabrication, and material handling operations, the Ingersoll Rand ML1000K-1C80-C8 MLK Series Air Chain Hoist delivers a 1 Ton (2,200 lb) lifting capacity with an extended 80 ft lift and 8 ft control drop. Powered by compressed air, this hoist features a pull chain control, allowing operators to manually actuate the lifting mechanism for dependable load handling without the need for a pendant control station. Its long lifting height makes it well suited for facilities with high ceilings, multi-level production areas, and elevated overhead lifting systems.
Built on the proven MLK Series platform, this air chain hoist is engineered for continuous-duty industrial service with interchangeable internal components that simplify maintenance and minimize downtime. A 100% duty cycle, self-adjusting air-operated disc brake, enclosed planetary gearing, and anti-friction bearings work together to provide dependable lifting performance. The hook-mounted suspension and steel snap hook provide versatile installation across cranes, monorails, and other overhead lifting applications.
