1. A monitoring system for at least one of traction force and compression force in an energy guide chain having a plurality of hingedly interconnected chain link members for protectedly guiding cables, hoses or other lines, including:

  • at least one force sensor for measuring at least one of a traction force and a compression force transmitted between an entrainment member and a moveable end of the energy guide chain, andan evaluation unit for evaluating the measurement signals detected by the at least one force sensor,wherein the at least one force sensor is in the form of a connecting member for fixing the moveable end of the energy guide chain to the entrainment member and includes at least one web extending substantially transversely to a direction of at least one of the at least one traction force and the compression force,wherein the at least one web is stressed in flexing in an event of the at least one traction force and compression force acting in a longitudinal direction of the chain and has at least one elastically deformable flexural region with an associated sensor device for measuring a deformation produced by flexing, andwherein the at least one force sensor includes a first flange which is made in one piece with the at least one web, the first flange having fixing means to fix the at least one force sensor to the entrainment member.
