Ingersoll Rand "MLK" Series Compressed Air Hoist / Pneumatic - Range from 250kg to 1000kg
Model: MLK Series Air Hoist / MS-3396Super heavy duty, high speed production hoist.
Serving industry for over 25 years, the rugged and reliable MLK series share a common design with many interchangeable parts. With high speeds and precise spotting, these hoists are ideal for high production cycle operations. Both spark resistant, designated with a KR suffix, and slow speed precision spotting models, deignated with a KS suffix, are offered.
MLK series hoists come complete with 10 feet of standard lift and either 6 feet of pendant control or 6 feet of pull chain control.
Features
- Meets ASME B30.16 Specifications.
- 100% duty cycle. MLK/HLK are rated as HMI duty classification A5, severe duty. This equates to FEM 9.511 duty classification 2m.
- These hoist are ideal for the harsh environments found in steel mills, foundries and electroplating operations. These are also ideal for high duty cycle applications.
- Pull chain or pilot pendent controls provide precise spotting capabilities. For even more precise control MLKS slow speed models are available.
- Self adjusting, air operated disc brake is spring applied and air released. Wear tested to over 1 million cycles before replacement.
- All rotating parts are supported by either ball or roller type bearings. Unique planetary gearing system assures long life.
- Thoughtful design includes parts interchangeability, inlet swivels, exhaust air chain lubrication, control adjustment screws and easy conversion from pull chain to pendent control.
- Spark resistant models and a wide range of options and accessories are available.
Rugged Construction for Severe Duty Use
- Robust high strength aluminium housing with durable powder coated paint finish.
- Insensitive to dust and humidity.
- 100% duty cycle multi-vane-motor - Avoids downtimes.
- Corrosion resistant load chain.
Efficiency
- High lifting and lowering speeds.
- Low air consumption.
- Precise load positioning through pilot pendant of pull chain.
- Low noise level (89 dBA).
Versatility
- Numerous options available for adaptation to your application: chain containers, rigid mounting trolleys, CE compliant versions, spark resistant versions suitable for ATEX zone 1 applications.
