Abstract: A portable zip line emergency brake system intended to stop or slow down a zip liner (or load) on a cable while giving the control to the device user or operator on the opposite end of the zip line. As an out of control rider comes down the zip line the operator will lock the device onto the cable and roll it out onto the zip line using a combination of sending force by the operator and gravity to meet the rider's pulley. The device is adjustable for different riders' estimated weights. Once the rider's pulley comes in contact with the device far out on the cable it will use a lever camming action between two brake pads on the cable as it reverses direction. As the brake is engaged it will stop or slow the rider. The operator can then pull the rider to the end safely.
