Designed for dependable overhead lifting in corrosive or harsh operating environments, the Ingersoll Rand ML500KR-3HAR10-R6U Air Chain Hoist combines a 1/2 Ton (1,100 lb / 500 kg) capacity with a 10 ft lift and 6 ft control drop for efficient material handling. 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. Equipped with a 2 Motor Pendent Control, this model provides independent operation of both the hoist and a motorized trolley for accurate vertical lifting and horizontal load travel. A bronze snap hook provides secure load engagement for applications where corrosion-resistant hook components are preferred.Engineered for reliable industrial service, the ML500KR-3HAR10-R6U 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. Supplied without a chain container, this hoist is well suited for marine facilities, processing plants, maintenance departments, and industrial applications requiring powered lifting, powered trolley travel, and corrosion-resistant hook components.Type: Air Chain Hoist | Series: MLK Series | Model: ML500KR-3HAR10-R6U | Capacity: 1/2 Ton (1,100 lb / 500 kg) | Lift: 10 ft | Control Drop: 6 ft | Control Type: 2 Motor Pendent Control | Top Suspension: Top Hook | Bottom Hook: Bronze Snap Hook | Chain Container: None | Chain Falls: 2 | Load Chain Size: 4 12 mm | Air Inlet: 1/4 in.
