1/4 Ton Ingersoll Rand MLK Series Airhoist
Pendant Controlled
Spark Resistant

Spark-resistant features

MLKR and HLKR spark-resistant hoists have been designed to give maximum protection in explosive and other hazardous environments.

Components for spark-resistance include:

• Bronze hooks
• Bronze trolley wheels
• Stainless-steel (one part reeving) or aluminum (two parts reeving) lower hook blocks
• Aluminum stop ring (1/4-ton models)
• Stainless-steel load chain
• Stainless-steel pendant levers and bronze valve caps
• Spark-resistant pull chains

The load capacity and speeds of MLKR and HLKR Series units are reduced. A restricted motor is used to accomplish this, as stainless-steel chain is not hardened and strength is less than standard alloy chain

• The Ingersoll Rand MLK family of hoists is suitable for A5 / H5 severe-duty use in the 1/4 to 1 metric ton range. The MLK Series is designed to be used as a highspeed production hoist; the MLKS* is better suited for slow-speed spotting..
• 100 percent duty cycle enables continuous operation
• Dust, dirt, moisture, and corrosive gases kept out of the motor by air pressure — ideal for foundries and electro-plating applications
• Minimum chance of electrical shock make air hoists ideal for highly flammable environments such as chemical plants and refineries; spark-resistant modvels also available
• Simple pull chain speed and directional controls provide precise load-spotting capabilities; easy-to operate pendant air valves provide a variable control signal with adjustable response by a variable orifice. For more precise control, MLKS slow-speed models are available
• Motor, brake, and throttle parts are interchangeable with all current Ingersoll Rand air chain hoists
• Ingersoll Rand air chain hoists are designed and constructed for trouble-free maintenance
