The BJT series transfer trolley is powered by cable. The power source 360V-690V alternating-current is supplied to the traction motor by cable, which is controlled by control system to make the cart start,stop, move forward, back forward. The cable can be collected and released by the coiling device installed underneath the trolley.PLC system is available to realize full automatic operation. The series rail transport cart can be used in occasions such as severe environment, high temperature,and anti-explosion.If the running distance is longer than 30m, our advince is using the magnetic coupling drum, which is effective for cable rolling. When the running distance is longer than 50m, a cable arranger will be added to help the cable rolling. The max running distance is up to 200m-400m.
