2.  INTRODUCTION

Ideal for workshop or roadside use, these jacks take the effort out of lifting heavy plant, tractors and commercial vehicles. Models feature dead 

man’s control for extra safety  (detachable on Model No’s YAJ15-30DC.V2 and YAJ20-40DC.V2 making these models extremely portable)    

and multi-position locking handles. Each jack is supplied with a 45mm and 75mm extension to help close the gap between the saddle of the 

jack and the jacking point. Model No. YAJ20-40LR also offers a long reach chassis, ideal for accessing deep set jacking points.
