HangLadder FlangeClamp

Movable anchor point for HangLadder for vertical and eccentric manholes (ANSI & API 20” & 24” flanges).


Safe entry and rescue from confined spaces, especially if it concerns horizontal manholes, is not a sinicure! Particularly complicating because of the angular transition from tubelure to vertical wall of the vessel. In addition, horizontal manholes are often located at large (er) height in reactors with only small platforms and the distance from flange to platform railing is low.

Perfect system for entering confined spaces safely

The HangLadder Flange Clamp features a hole pattern for mounting on ANSI & API 20” & 24” standard flanges. In combination with the HangLadder and a tripod or TwinSleeve davit (and fall arrest device with integrated rescue function, fall arrest devices, person winches, rescue and evacuation devices), the HangLadder Flange Clamp is a perfect modular system for safely entering confined spaces!

Extra advantage

HangLadder-FlangeClamp in combination with the HangLadder®, TwinSleeve davit and tripod are modular and ideally matched safety devices as a ‘kit’ for safe entry and rescue from confined spaces through vertical and eccentric manholes.
