Hoisting Winch Troubleshooting Turkey

Alatas Turkey was assigned to a troubleshooting job for the hoisting winch on a 30t Fukushima hydraulic deck crane. We were called in as our client’s Crane #4 downward hoisting function was not working.

Our engineers ran checks on all hoisting parts and the hydraulic line and then dismantled the hoisting controller block and lower limit block for overhauling. After transportation, the Istanbul Alatas workshop team carried out maintenance on the hydraulic blocks and installed back onto the crane.
