Min. height
The parameter shows the minimum allowable distance between the supporting surface (ground, floor) and the jack in the lower working position, that is, the minimum height from which the machine starts to be raised. Before buying a tool, it is important to correlate this parameter with the minimum vehicle clearance.
Max. lifting height
This parameter shows to what maximum height the jack can lift the load. Usually, on average, this parameter is in the range from 30 to 50 cm, which is quite enough to change the wheel or access the handbrake cable. At the same time, rack jacks are capable of lifting loads to a height of up to 1 metre, although such tasks do not occur so often in domestic use.
Quick-lift pedal
The presence of a
quick lift pedal in the design of the jack.
When you press such a pedal, the jack platform rises with minimal effort, but at high speed. This relieves the user of the need to pump up the jack "idle": by pressing the pedal, the working platform quickly covers the distance to the lower edge of the load, and you need to pump the handle only in the process of lifting itself, without wasting time and effort on free running. The pedal is mainly equipped with rolling models (see "Type") of a professional level.
