Manual Release Unit

Caldwell's patented Rig-Release hook is a safe and simple way to release rigging remotely, protecting workers on the job site and making lifts more efficient. You just hook the unit to your crane or spreader beam, then attach the sling(s) directly to the Rig-Release, which is designed so that it cannot release the rigging while under load when used according to operating instructions. The crane operator lifts the load, sets it, and once the crane line is slack, pulls the release rope manually or via remote control. The Model RR is a cost-effective option for safer rig releasing.

Product Features

Cost-effective option for safer rig releasing
Rope guide allows rigging to be released when hook is either above or beside the operator
If hook is located below the operator, please ask about the Upward Pull option
Rated load capacity can be lifted from either Lift Arm or the lower Strip Sling hook
Do not exceed capacity on hook
When the minimum load is applied, the inner body assembly sits in the Lock & Capture position and cannot be released
Inner body assembly only allows slings to release when the load line is slack
Release rope has built-in breakaway chain to prevent damage to the inner body assembly
Additional springs can be added to accomodate heavier sling weights
