Norlift crane: emergency repairs to Zollern hoist winch
Norlift Crane, SWL 30t x 26m. Emergency Repairs on Zollern Hoist Winch
The vessel was stuck in Thailand with a seized hoisting winch, the Zollern planetary gearbox, type ZHP 4.31 was found completely smashed up. With only onboard means, some old spare parts and the ingenuity of our crane specialist engineer, ALATAS managed to re-build the gearbox into a temporarily functional state. Naturally, ALATAS already sourced a competitively priced replacement gearbox that will be installed soonest.
