Robust and lightweight lifting rig for the removal and installation of tankwashing equipment. The stable base formed by the three adjustable feet coupled with the unit`s height enables drop pipes up to 5 mtrs long to be raised or lowered easily and safely, using a fail-safe chain block and endless chain. Easily handled and erected and because the legs are constructed from tubular aluminium the framework offers a high strength/weight ratio. The feet automatically adjust to accommodate deck cambers, and are fitted with rubber seating pads for firm grip. Important : It is essential to keep all safety chains and retaining pins in position, as directed, at all times.
