GIS Hoist for Wind Turbines (GPW Series)

Maintaining wind turbines means moving tools and spare parts to heights that ordinary hoists never see. The GIS GPW series was developed exactly for that job: a special version of the proven GP electric chain hoist, optimised for lifting heights up to 200 m inside the tower, from the ground straight up to the nacelle.

Key features

• Based on the proven GIS GP 500 / GP 1000 electric chain hoists — up to 1000 kg on a single chain fall
• Lifting heights up to 200 m: spare parts and tools travel from the ground to the nacelle in one hoist path
• Lifting speed up to 16 m/min with automatic switch-over from high to creep speed shortly before the stroke end (geared limit switch), so toolboxes land softly and nothing falls out
• External limit switches for the hook end positions in addition to the geared limit switches
• Temperature monitoring with automatic motor shutdown in case of overheating — powerful motors with low operating temperature
• Tempered special chain and a load hook with protective cover, so the hook cannot snag anywhere on the long way up
• Protection class IP65, insulation class F, DC spring-loaded brake, adjustable slipping clutch outside the flow of forces
• Options: manual or motorised trolley, chain container sized for the lifting height, operating data counter, brake with manual release, locking load hook, grease for low-temperature use, special suspensions, worldwide operating and control voltages

The GPW is a project product: GIS builds each hoist to the turbine — lifting height, chain container, voltage, trolley and suspensions are specified per installation. Send us your parameters and we will come back with a tailored offer and technical advice.
