Abstract
A linear actuator is configured to be connected between a platform and a structure or ground for displacement of the platform relative to the structure or the ground. The actuator comprises a base, and an output displaceable linearly relative to the base. A first plurality of idlers are on the base, and a second plurality of idlers are on the output. An actuator unit has a reciprocating rotational output. A tensioning member has a first end connected to the rotational output of the actuator unit, and a second end connected to an anchor point on one of the output and the base, the tensioning member being routed from the rotational output, through the first plurality of idlers and the second plurality of idlers and to the anchor point for converting a winding/unwinding of the tensioning member into a translation of the output.
