Built for continuous lifting in manufacturing, maintenance, fabrication, and material handling operations, the Ingersoll Rand ML1000K-1C20-C16U MLK Series Air Chain Hoist combines a 1 Ton (2,200 lb) lifting capacity with a 20 ft lift and 16 ft control drop to provide dependable overhead lifting in demanding industrial environments. Powered by compressed air, this hoist features a pull chain control, allowing operators to manually actuate the hoist for smooth lifting and lowering without the need for a pendant control station.
The MLK Series has been trusted in industrial lifting applications for more than 25 years and features a modular design with interchangeable service components that simplify maintenance. A 100% duty cycle supports uninterrupted operation throughout production shifts. At the same time, the self-adjusting air-operated disc brake, enclosed planetary gearing, and anti-friction bearings provide reliable load control and smooth lifting performance. Standard hook suspension and a durable steel snap hook allow for versatile installation across a broad range of overhead lifting applications.
