Built for continuous lifting in manufacturing, maintenance, steel processing, and material handling operations, the Ingersoll Rand ML1000K-2C10-C6U MLK Series Air Chain Hoist combines a 1 Ton (2,200 lb) lifting capacity with a 10 ft lift and 6 ft pendant control drop to provide dependable load handling in demanding production environments. Its air-powered design makes it well suited for facilities where pneumatic equipment is preferred, while the pilot pendent control (a suspended hand control that allows precise load positioning) helps operators accurately raise and lower loads during repetitive lifting tasks.
The MLK Series has been proven in industrial service for more than 25 years and features a common platform with interchangeable service parts to simplify maintenance. A 100% duty cycle allows continuous operation throughout production shifts, while the self-adjusting air-operated disc brake, planetary gearing, and anti-friction bearings contribute to reliable performance in high-cycle lifting applications. Standard swivel top hook suspension and a steel snap hook provide flexible installation for a wide variety of overhead lifting points. Product details are based on the manufacturer catalog and supporting documentation.

Applications:
- Moving components through high-production manufacturing and assembly lines.
- Supporting maintenance and repair operations in industrial plants and processing facilities.
- Handling materials in steel mills, foundries, and electroplating operations where continuous-duty lifting is required.
- Positioning machinery, tooling, dies, and fabricated components during installation or service.
- General overhead lifting where accurate load control and rapid lifting cycles improve workflow efficiency.
FAQs:
- Q: What does the 6 ft pendant drop refer to?
A: It is the length of the pendant control suspended below the hoist, allowing the operator to safely control lifting and lowering while standing away from the load. - Q: Is this hoist suitable for continuous production use?
A: Yes. The MLK Series is rated for a 100% duty cycle with HMI Duty Classification A5, making it suitable for continuous industrial operation when used within its rated capacity. - Q: What type of suspension does this model use?
A: This model features a swivel top hook for mounting and a steel snap hook on the lower block for attaching the load. - Q: Can this hoist provide precise load positioning?
A: Yes. The pilot pendant control is designed to provide smooth throttle response for accurate load spotting during lifting operations.
