Quick action locking system for fixing construction frame to lorry chassis frame, comprises fixed and resilient locks mounted in both frames

摘要

The substantially non-rotatable frame (2) is fixed to a chassis frame (1) which can rotate a little using a system comprising a fixed lock (7) in one of the frames and a resilient lock (8) in the other frame. A spring-loaded catch (9) is provided between the two locks, comprising a locking body (10) with a conical sleeve (11). A locking cone (12) movable in an axial direction relative to the fixed lock can be pulled out in a downwards direction in order to release the locking body.
