Using the Davit Arm Assembly
The Davit Arm Assembly is designed with offset adjustability and
360 degree rotation. This Davit Arm Assembly allows the combined
use of an entry/retrieval winch and a self-retracting lifeline (SRL).
1. Adjust the offset by pulling the pin assembly and selecting the
one of three holes offered in the Davit Arm receiver tube.
(See C2).
Rescue
The Davit Arm can be rotated 360 degrees in a rescue/retrieval situ-
ation so an injured worker can be moved to a safe environment. The
Portable Fall Arrest Post must be used in a vertical position at all times
to effectively rotate the Davit Arm.
When using the DH-AP-1, 2, 3 as a rescue device, remember that the maximum
number of people that can be attached to the system is three. If a rescue could involve
more than three persons (including the person being rescued), additional anchorage points
must be identified to provide adequate protection for everyone.
