Hang the car and counterweight. Take a dynamometer and weight the counterweight then the car. Take the ropes off and take amp readings in both directions. Then put the ropes back on and remove your block & tackle. Place a load on the car to create a balanced load. Take amp readings in both direction. By now you should be on track to understand why your motor is overheating. Also lift your brake electrically and check and see you have clearance.
