MOTION -BASED FAIL SAFE BRAKING FOR TROLLEYS

According to embodiments of the present disclosure, a motion based fails safe braking for trolleys is disclosed herein. The trolley includes a brake system that allows for safe operation of the trolley on ramps. The trolley may include various mechanical elements that act as force and displacement multipliers connected to a fixed wheel with a Deadman's brake. The wheel is connected to a hitch point of the trolley. During normal operation, the vehicle that drags the trolley exerts a pull force at the hitch point which releases the brakes, in turn causing the trolley to move. When the tugging operation has ceased, there is no pull force. This releases the brake lever and engages the brake. On gradients and ramps, this braking system ensures there is minimal or no trolley motion.
