Designed for dependable overhead lifting in manufacturing, maintenance, assembly, and material handling applications, the Ingersoll Rand ML500KS-2C27-C60 Air Chain Hoist combines a 1/2 Ton (1,100 lb / 500 kg) capacity with a 27 ft lift and an extended 60 ft pendent drop for applications requiring remote hoist operation from floor level. Part of the MLK Series, this pneumatic chain hoist features a six-vane air motor engineered for continuous 100% duty-cycle operation, delivering reliable lifting performance throughout demanding industrial shifts. The responsive 2-button pendent control enables smooth and accurate load positioning, while the steel snap hook with safety latch provides secure load engagement.
Engineered for reliable industrial service, the ML500KS-2C27-C60 features a spring-engaged, air-release non-asbestos disc brake that automatically secures suspended loads whenever the controls are released. Upper and lower limit stops help prevent excessive chain travel, while the compact hook-mounted configuration minimizes installation headroom requirements. This configuration is supplied without a chain container, making it suitable for installations where a chain bag is not specified by the manufacturer.
