This overhaul of an Appleton API 2C telescopic crane was on board of a US Navy Supply Ship that experienced hydraulic leakage from the luffing cylinder and telescopic boom cylinder. 

A team of Alatas specialists were sent aboard to dismantle the telescopic boom and extract the telescopic cylinder. The team were also tasked with dismantling and removing the luffing cylinder from the crane.

So we could perform a complete overhaul, both cylinders where air freighted to our specialist Alatas Hydraulic Workshop in Singapore. As well as new cylinder seal sets, the cylinder barrels were honed and the cylinder rods were re-chromed.

The repaired cylinders and the new hydraulic hoses and fittings were air-freighted back on board and reinstalled by an Alatas Riding Squad.

In addition to the cylinder overhaul, the crane also was refurbished with a new main control valve, function tested and overload tested.
