Wind turbines are used to generate electricity in areas with strong, steady winds – either on land or offshore. Almost all modern turbines being produced today use a three-bladed, upwind design. Wind turns the blades, which spin a shaft. The shaft connects to a generator, which produces electricity.
Electric chain hoists are used to carry out maintenance work on windmill machinery and for lifting spare parts. The hoist can be mounted to a jib crane within the nacelle of the turbine. Using the hoist for service allows maintenance staff to safely raise and lower turbine appliances for repair or replacement through the hub, as opposed to accessing the nacelle through the hatch or along the tower.
Workshop cranes can be used in the process of manufacturing windmills. These cranes include wall console cranes, bridge cranes, jib cranes and manual hoists.
