Air Chain Hoists: Spark Resistant

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
