Anode Screw Jack

AML Motorised

Anode Beam Positioning System

Power Jacks are continuously developing new products to keep customers designs at the leading edge of technology and performance. However we still support all our older technology (including geared air motors), which are still in service worldwide. One of the latest developments is the AMT0300 anode jack. This is the cornerstone of the Generation 4 anode beam positioning system. The system is designed to meet the requirements of the latest pot designs, which have seen a significant increase in physical size and performance requirements. Both the new anode jack and its system have successgully completed potline testing and are now used in major potlines.
