Troubleshooting and Recertification of Luffing Cylinder

Alatas UK has recently been contracted to carry out troubleshooting and recertification of a luffing cylinder on a Hydralift crane. This project involved two Alatas services: Field Service and Workshop Repairs to help the client get back up and running within 1 week before their offshore construction vessel left port.

First, our Hydraulics Specialist and Focal Point for the project carried out an in-depth analysis of the crane. They determined that the luffing cylinder wasn’t functioning correctly and needed to be removed by a team of Alatas service technicians and inspected in the Alatas workshop.

After we transported the cylinder to the Alatas workshop, our engineers found the cylinder was bypassing oil and needed an urgent overhaul and pressure test.

Once completed, the cylinder was reinstalled on the crane by the service technicians, load tested and signed off by our senior service technician and our Hydraulic Focal Point.
