<p>A device for monitoring the tractive force generated by a cylinder-piston assembly on a member to be moved thereby comprises a spring mounted between the cylinder assembly and the member to be moved such that the force generated by the cylinder-piston assembly is transmitted to the spring to effect movement of a first portion thereof with respect to a second portion thereof. An actuatable switch comprises the first switching element mounted for movement with the first portion of the spring and a second switching element fixedly mounted to the second portion of the spring, the two switching elements configured to actuate the switch when a predetermined path of travel of the first portion of the spring is exceeded.</p> |
