20ft Semi-Automatic Container Spreader

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