The idea of the ELME Add-on Kit is to facilitate the possibility of adding options to your spreader after the initial purchase, using genuine parts that are designed to specifically fit your spreader. Hydraulic stop cylinders with mechanical locking system serves as an additional assurance for the operator to know the position of the beams, especially when handling 30ft containers where the hydraulic stops are a demand. By locking the extension beam to the preferred position it will also reduce the risk of deforming the piston rod of the extension cylinder in the event of an accident.
