ABSTRACT:
A rope grab for protecting a worker at an elevated position from a fall. The rope grab is disposed on a vertically extending safety line and is connected to the worker by a lanyard. The rope grab includes housing having a pivotable actuator mounted thereon. The actuator includes an serrated extension for engaging the safety line. A rupturable capsule containing an indicating liquid is located in the housing. The actuator is connected to the lanyard to secure the worker to the rope grab and is pivotable upon a downward pull thereon to move the serrated extension from a first position to a second position. When the serrated extension is in the first position it engages the safety line slightly to permit the rope grab to be slid therealong. When it is in the second position it tightly engages the safety line to preclude the device from being slid along said safety line, and causes the automatic rupturing of the chamber, whereupon the indicator liquid flows onto a portion of the rope grab and a portion of the safety line. The actuator is also arranged to be moved to a third intermediate position wherein the rope grab is precluded from sliding along the safety line but the capsule is not ruptured.
