Abstract
The invention relates to a monitoring system for tractive and compressive forces in a power track chain (1) for protected guidance of cables, hoses etc. The monitoring system comprises at least one force sensor (10, 90) for measuring a tractive or compressive force transmitted between a driver (4) and a moveable end (3) of the power track chain, and an evaluation unit (12) for evaluating the measurement signals detected by the force sensor. The invention is characterized by the design and arrangement of the force sensor (10, 90). This force sensor is designed as a connecting member for attaching the moveable end (3) of the power track chain (1) on the driver (4) and comprises at least one web (32, 34, 92) extended substantially transversely to the direction of the tractive/compressive force. The web has at least one elastically deformable bending region (321, 322, 341, 342) with an associated sensor (621, 622, 641, 642) for measuring deformation produced by bending.
