The Enjue semi-automatic container spreader is fixed to the hook of gantry, bridge, and portal cranes. Twist lock control is carried out mechanically using wire rope pulling. Hooking/unhooking is carried out without the help of crane workers. The simplicity and convenience of spreader installation allow for converting from a hook crane into a container crane in a short time. There is no necessity to arrange a power supply for the spreader and update the crane control circuit.
