RSL are exclusive distributors for AVS excavator and crane hydraulic rotators.  We also stock Liebherr worm drives and slew drives

    It is hugely important to specify the right quality and size rotator for your machine.  Due to the large shock loadings that are achievable from an excavator, please contact us for advice on the right size for your situation.

AVS rotators are a complete G rotor type rotator which has internal pipework to allow for a double acting hydraulic attachment.  Great for excavator grabs, and lorry cranes or our car dismantling pincers as shown on the video below! 

G rotor driven rotators have better holding torque than a piston type rotator, they are also less aggressive when starting. Piston type rotators usually cannot handle high pressure systems over 200 bar. An AVS unit has fine starting torque and  holding torque and the rotation can be used up to 320 bar, AVS rotators are  premium class, made in Austria

      Liebherr worm and slew drives need a separate pipe swivel unit in the centre to pass hydraulic services to the attachment (pipe rotators are held in stock). When the there is no hydraulic flow the slew is locked in position.  Great for our Tree shears, pole erectors etc. We have found through selling many different manufacturers of worm drive that Liebherr units are unquestionably the best quality and most reliable.

    RSL is the exclusive distributor for  AVS and Liebherr hydraulic rotators in the UK. These units are designed and manufactured in Austria and the Liebherr  units are manufactured in Germany.
