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.
