Crane system and an associated method thereof

Abstract:

A crane system for a wind turbine is disclosed. The crane system includes a support structure, a movable structure, a slidable device, a first actuator unit, and a plurality of second actuator units. The slidable device includes a base, a retention component, and first, second, third, and fourth pairs of clamping arms. The base is coupled to the support structure. The retention component is coupled to either side of the base to define a channel between the retention component and the base. The first and second pairs of clamping arms are spaced apart and coupled to each other and to the base. The third and fourth pairs of clamping arms are disposed within the channel, spaced apart, and coupled to each other. The first actuator unit is coupled to the slidable device and each second actuator unit is coupled to the first, second, third, and fourth pairs of clamping arms.
