These jacks are mainly used with vehicles fitted with a compressed air tank.
The BRA series models are fitted with a manual pump and manual release so that they can be operated as a portable bottle jack.
Lowering is controlled by adjusting the release valve.The operator will always be in control of the descent even if the air supply is interrupted.
They have a fast load approach screw and a high performance pneumatic pump with remote control drive.
For an optimal use of the jacks a working pressure of between 6 and 8 bars is recommended.
