Ingersoll Rand ML250KR-2DAR21-R7U MLK Series Air Chain Hoist | 1/4 Ton Capacity | 21 ft Lift | 7 ft Drop | Bronze Snap Hook | Pendent Control

Designed for dependable overhead lifting in corrosive or harsh operating environments, the Ingersoll Rand ML250KR-2DAR21-R7U Air Chain Hoist combines a 1/4 Ton (550 lb / 250 kg) capacity with a 21 ft lift and 7 ft pendent 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. The responsive 2-button pendent control enables smooth and accurate load positioning, while the bronze snap hook provides secure load engagement for applications where corrosion-resistant hook components are preferred.

Engineered for reliable industrial service, the ML250KR-2DAR21-R7U 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 suitable for maintenance departments, processing facilities, marine-related applications, and industrial environments requiring corrosion-resistant lifting components.
