Afkos Industries successfully commissioned a hydraulic stacking system to raise shovels in Indonesia.
The hydraulic jacks each have a capacity of 565 ton and a stroke of 1,700mm. The long stroke eliminates the need for multilifts with packers all in a single lift.
Each jack carries a weight of 2.1 ton with a pressure rating of 700 BAR. The base cradles are 2.3 metres in diamter at the bases and manufactured to house each jack. The weight of each base is 4.2 ton. Each hydraulic jack is fitted with an anti-intensification valve and a safety load lowering valve.
All components are manufactured by Afkos Industries. These images detail the process of design, manufacturing and commissioning of the equipment.
