Easy entry device for manhole shaft, comprises grip bar holder with claw for hooking onto rung

摘要

A connection part (3) on the outside of the holder (1) for the grip bar inside the shaft includes a claw (4) for hooking over an arm (5) of a rung (6) inside the shaft and also includes a slanting clamp surface (7) for a clamping piece (8) with a glide surface (9) for cooperating with the clamp surface and a clamping bar for the lower edge of the rung. A clamping means (e.g. screws or bolts) is used to secure the clamping piece to the connection part and to move the piece towards the claw via the clamp surface. The grip bar has a handle at one end and can be moved in its length direction along a guide in the grip bar holder. The grip bar can also be rotated about its length axis.
