Abstract An elevator link arranged for use in providing a compensatory response to a load applied thereto, is disclosed. In at least one aspect, the elevator link comprises first and second actuable devices configured operable with a piston rod by way of respective non-compressible fluids. The piston rod has an internal chamber for accommodating a compressible fluid. The first and second actuable devices are arranged in operable association with the piston rod such that the non-compressible and compressible fluids are cooperable with each other so as to allow the elevator link to be operable toward and/or from one of an extended condition and a retracted condition in response to the load. Each actuable device comprises a housing, whereby opposite free ends of the piston rod are slideably associated with a respective housing.
