DC wind chain hoist
A good hoist for the maintenance of wind power stations
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.
