Abstract
A device for monitoring the status of a railcar handbrake having a hand operated handle, which device has a load bearing member configured to be inserted in the linkage of a railcar handbrake system so that the force applied to the brake system passes through the load bearing member. A strain gauge mounted on the load bearing member measures the strain. The information from the strain gauge is indicative of the force applied by the handbrake to the brake and is used to determine the status of the handbrake. Means for determining motion of the railcar is also provided. In one form, if it is determined that the brake is on and the railcar is in motion, information, such as an alarm, is transmitted. A system and method of monitoring a railcar handbrake are also provided.
