Automatic locking device for track mounted gangway |
摘要 |
A locking device and apparatus is disclosed. The locking device is particularly suitable for use in combination with a device such as a track mounted gangway and safety cage to reduce the ability to reposition the gangway and safety cage along a track surface while in the lowered access position. The locking device preferably includes a lever assembly and a pivot assembly having a friction pad connected to the lever assembly. When the lever assembly and/or gangway device is adjusted in a first direction, the friction pad applies pressure on the track surface and moveability between the gangway and the track surface is reduced.
