Overhaul & installation of rope winches for a Liebherr 4 rope crane
 

ALATAS Singapore overhauled & installed Rope winches on a Liebherr 4-rope crane

ALATAS Singapore overhauled & installed Rope winches on a Liebherr 4-rope crane.
ASG attended at Singapore Anchorage and removed one unit closing winch and 1 unit holding winch for a complete overhaul in ALATAS mechanical workshop.
Planetary wheels, lamella brakes and drive sleeves were found worn and were replaced with original spare parts from Zollern Germany.
The winches were boxed up and torque according to our workshop manual and re-installed.
The electronic 4-rope synchro control system then was adjusted and calibrated by our senior Liebherr Engineers.
