ENERPAC says its RC-756 75t hydraulic cylinders proved effective in the concrete casting process at Sydney Ports Corporation’s Port Botany Container Terminal Expansion.
According to ENERPAC, its cylinders were selected to assist in striking the 220t concrete segments to ensure no damage occurred during lifting.
The RC-756 hydraulic cylinders are said to employ 700 bar high-pressure technology to reduce its weight and size while maximising compact lifting power. The 29.5kg ENERPAC jacking cylinder is just 285mm high with a stroke of 156mm, the units were powered by an ENERPAC ZU4 electric pump high-strength alloy steel cylinders.
ENERPAC says its ZU4 electric-powered portable hydraulic pump used to power the RC-756 cylinders on the Port Botany project is a cool-running, energy-saving pump which sets new durability standards and lower operating costs. The ZU4 series is best suited to medium-to-large cylinders or hydraulic tools or for use wherever high-speed, intermittent duty cycle is needed.
The Senior Project Engineer says the ENERPAC RC-756 cylinders accomplished the job well and while this type of job doesn’t come around very often, it would consider using ENERPAC cylinders for striking again if required.
