JACK SIMPLE EFFECT WITH BUILT-IN PUMP
Equipped with a piston of chrome pumping Ø 16 mm combining a weak effort on the lever (650 mm) and an important flow, this jack pariculièrement is pariculièrement adapted for the lifting of loads.
It can be used only like a jack "bottle" or gone up on an arm of lifting (bracket, goat...).
Partly low, the connection is ensured by a hoop assembled on a tenon of support allowing the rotation of the jack 360°.
At the other end, the stem of the jack is bored.
The jack is equipped with a valve of limitation of pressure for safety in the event of overload and with an ergonomic decompression with wordwrap.
It is entirely dismountable.
