Abstract:
The invention relates to a test lever system (1) for monitoring the traction behavior of a transport system (2), particularly an elevator system, comprising a test lever (8) which consists of a load arm (14) and a force arm (13). A discharge in the form of a monitoring force is introduced by means of the test lever (8), via a carrier cable securing device, into a cable which is to be tested.
