Wind Chain Hoist

Easy maintenance and repair

Day by day, rotors turn under changing conditions. If the system comes to a standstill as the result of malfunctions or maintenance work, power generation comes to a halt. The required spare parts and equipment have to be lifted into the nacelle as quickly as possible. Here the Demag DC Wind chain hoist with hook paths of up to 130 m is a proven lifting device in wind energy systems. Fitted to slewing jibs or travelling portals, it transports loads weighing up to 1000 kg with ease.

In accordance with the operating conditions, the chain hoists are fitted with larger chain collector bags, or alternatively the chain is led through a tube into a separate container. In addition, the highest and lowest hook positions are limited by limit switches, an optional locking device secures the trolley against unwanted movement. The Demag DC Wind chain hoist, which is specially designed to meet the requirements of the industry, is one of the most frequently used hoists by leading manufacturers.
