Overview of Requirements
BHP engaged Hydraulic Energy Australia to design a hydraulic power unit to assist with cylinder change out on their fleet of Liebherr 996 excavators. The HPU was deigned with wireless pendant control to ensure operator safety during use. The HPU circuit design incorporated reverse flow filters for both extend and retract functions being used during a cylinder change out. All necessary adaptors and tooling to suit various OEM machines were integrated within the HPU for field operations.
