EWP Hydraulic Services in Sydney

Sydney's access fleet works under sustained hydraulic load. The high-rise residential construction, metro rail projects and the WestConnex-era civil works keep booms extended and scissors elevated for hours at a time, and the hydraulic circuits that hold those positions — load-holding valves and cylinder seals — accumulate wear in proportion to the hours at load rather than the hours of movement. Harbour salt that reaches the inner western suburbs can work into hose fittings and valve body connections over time, and the variable summer temperatures in the basin affect hydraulic fluid viscosity, meaning fluid that's in good condition in winter may behave differently on a forty-degree January afternoon.

EWP Australia provides hydraulic services across greater Sydney — pressure and flow testing to identify the root cause of a fault before committing to parts, cylinder resealing and overhaul when drift or bypass shows internal wear has passed the acceptable threshold, hose inspection and replacement with rated assemblies, pump assessment and service, and load-holding valve testing. Hydraulic fluid condition is assessed and changed on a schedule that suits the machine's duty and operating environment, and filter condition is checked at every service.

Hydraulic Services in Sydney — Common Questions

Our boom drifts downward slowly when the controls aren't operated — is that dangerous?

Boom drift is a safety fault: a machine that won't hold position has a failed or bypassing load-holding valve or cylinder seal. It should be taken out of service until repaired — the drift rate tends to worsen as wear progresses, and a drift that is slow today can be significantly faster after another day of operation.

We've topped up the hydraulic reservoir twice in the past month — where is the oil going?

A reservoir that needs repeated topping up has a leak somewhere in the circuit — it's just a question of finding it. External leaks show as oil weeping from hose fittings, cylinder rod ends, valve bodies or the reservoir itself; internal bypass past a cylinder seal doesn't always leave a puddle. We pressure-test the circuit to identify every leak path before any parts are committed.
