OVERVIEW OF THE JACK
2.1 General description
The jack is mainly composed of Sax, lifting platform, base, oil piston, pump.
The jack may act on the one manner, in order of the model selected by the user.
1. Air hydraulic pump (JA2000J-AIR)
The pressure from the pump or pump station pushes oil into the piston which put the piston in motion so that the
vehicle can be lifted to the height of the user selects. During the lifting process will the jacks safety locks automatically
work and make sure if a possible leak in the hydraulic system should accrue will the user will not get hurt and the vehicle will
remain in the position the safety locks is in.
To meet user needs, Jema Autolifte developed 3 different jack models in our Basic line series.
