Rolling jack (park jack) - mobile lifting equipment; hydraulic or pneumatic jack mounted on a trolley with wheels for easy feeding under a car or other load.

For car repairs, various types of jacks are used by owners and workshops - mechanical, hydraulic, pneumatic. In the practice of workshops (and in recent years, among car owners), hydraulic and pneumatic rolling (park) jacks are widely used, which have several advantages over bottle jacks:

Low pickup height - you can lift cars with a minimum ground clearance;
Convenient design that does not require special floor preparation for installation - this provides a wide base on wheels;
A simple job requiring little force.
Rolling jacks are primarily valued for the fact that to work with them you need to perform a minimum of movements, in most cases there is even no need to bend over or squat. This saves time and energy and reduces fatigue. And thanks to the low pickup height, such a jack is universal, it allows you to work with all classes and models of cars, SUVs and commercial trucks.
