Operation & Service Manual (VA) 39 ST1175
6 OPERATION
6.1 Introduction
The mobile column lifts are designed to provide maximum flexibility and ease of
use. A lifting system may consist of 2 to 28 columns in total.
The control system provides the following capabilities:

operating all column lifts simultaneously,

operating one pair of column lifts (per vehicle axle), referred to as operating in
pairs,

operating a single column lift.

Operating a single column lift or one pair of column lifts can be extremely
hazardous. Refer to section Safety when hoisting.
These possible modes of operation are available on every one of the column lifts,
without needing to set any selector switches.
6.2 Safety when hoisting
In principle, the individual and per-axle control over the column lifts is intended to
enable the vehicle to be raised horizontally, or alternatively to lower it onto axle
supports.
