Built for fast, precise lifting in assembly operations, maintenance departments, manufacturing facilities, and general industrial environments, the Ingersoll Rand ML250K-2C10-C6U MLK Series Air Chain Hoist provides a 550 lb (250 kg / 0.25 metric ton) lifting capacity with a 10 ft lift and 6 ft pendant drop. Its pneumatic drive delivers smooth, responsive operation using compressed air, making it an excellent solution for repetitive lifting applications where speed, reliability, and continuous-duty performance are essential.
Part of the Ingersoll Rand MLK Series, this air chain hoist features a compact design with a high lifting speed, making it well suited for production workstations, equipment maintenance, and material handling tasks. A planetary gear transmission provides efficient power transfer, while the self-adjusting, spring-applied, air-released disc brake securely holds suspended loads whenever air pressure is removed. The steel snap hook and pendant control allow safe, accurate load positioning throughout the lifting cycle.
