The RA series stabilisers are also fitted to the sides of machinery by welding or bolting and have adjustment from above the trapezoidal screw (without having to kneel down). The range is composed of three models with screws TR20, TR25, TR25 and TR30 and are sutiable for low and medium loads with the utmost practicality of manoeuvre from above and with special heights available on request. In the event of maintenance, the RA models, even if welded to the machine, allow the removal of the trapezoidal screw from above the stabiliser with the maximum of simplicity without having to lift the machine itself.
