The RT series levelling stabilisers are fitted to the side of the machinery by welding, or using bolts, and then adjusted for height by turning the head of the trapezoidal screw. The range is available from TR20 to TR60 and is composed of 6 models that are the most commonly used, and above all for use on heavy machinery that is housed indoors. For any maintenance, including the welded models, this series allows the removal of the trapezoidal screw from above the stabiliser and therefore avoiding the need to lift the machinery for its removal which for heavy machinery could be problematic.
