The team stationed at Alatas Singapore was tasked with the overhaul and installation of winches on a 4-Rope Liebherr crane.
When we attended the crane at the Singapore anchorage, we removed one closing winch unit and one holding winch to enable us to perform a complete overhaul in the Alatas mechanical workshop.
Job Scope for Installation of Winches on a 4-Rope Liebherr Crane
- Planetary wheels, lamella brakes and drive sleeves were found worn and replaced with original spare parts from Zollern Germany
- The winches were boxed up and torque according to our workshop manual and reinstalled
- The electronic 4-rope synchro control system was then adjusted and calibrated by our senior Liebherr Engineers
