1.3 DESCRIPTION OF THE LIFTING SYSTEM
The mobile column lift is a movable electrically driven hydraulic column lift used for
lifting heavy vehicles. It is used in set of four columns. But at least two lifting columns
are required to work at same time for lifting a vehicle.
The main components of the mobile column lift are shown below: (see figure 2):
1) Height sensor / encoder
2) Safety lock mechanism
3) Control case
4) Motor pump
5) Pallet jack
6) Battery (Not Included)
7) Front roller
8) Battery case
9) Forklift pocket
10) Lifting fork
11) Carriage
12) Hydraulic cylinder
Fig.2 column components
Each lifting column has a lifting capacity of 13,200 lbs. Consequently, four columns
have a total lifting capacity of 52,800 lbs.
Each column has its batteries to drive the motor pump (hydraulic power unit).
The control system on the lifting columns ensures that the columns are raised or
lowered synchronically. Each lifting column is equipped with a position sensor, which
transmits the height readings to the control system. The control system controls and
protects the lifting system during lifting or lowering as follows:
- At a difference in distance passed in height between the lifting columns of over 3/4"
(20mm) and less than 2" (50mm), an extra adjustment valve in the hydraulic system
opens and remains open until the difference has been cancelled out. The adjustment
happens in the lift, which has passed the largest distance.
- At a difference in distance passed in height of over 2" (50mm), lifting or lowering is
interrupted in the quickest lifting column. It will stop to until the difference has been
cancelled out.
In addition, the control system has been designed so that:
- Each lifting column can be operated separately
- Any pair of axles can be handled individually
