IMPORTANT SAFETY INSTRUCTIONS
- Read all instructions.
- If an extension cord is necessary, a cord with a current rating equal to or more than the equipment must be
used. Cords rated for less current than the equipment may overheat. Care should be taken to arrange the
cord so that it will not be tripped over or pulled.
- Always unplug equipment from electrical outlet when not in use. Never use the cord to pull the plug from
the outlet. Grasp plug and pull to disconnect.
- Let equipment cool completely before putting away. Loop the cord loosely around equipment when storing.
- To reduce the risk of fire, do not operate equipment in the vicinity of open containers of flammable liquids
(gasoline).
- Adequate ventilation should be provided when working on internal combustion engines.

8
- Keep hair, loose clothing, fingers and all parts of the body away from moving parts.
- To reduce the risk of electrical shock, do not use on wet surfaces or expose to rain.
- Use only as described in this manual. Use only manufacturers recommended attachments.
- ALWAYS WEAR SAFETY GLASSES. Everyday eyeglass only have impact resistant lenses, they are not
safety glasses.
- Use by untrained people could result in serious injury and/or damage.
- Do not use the lifting system outdoors if the wind velocities mentioned in paragraph 5.5 are exceeded
- If the lifting system is used outdoors do not leave the vehicles unattended in the lifted position. The wind
speed may change and exceed the safety limits.
- Danger of getting injured by electrical shock.
- Only remove the covers to carry out maintenance, ensure that the lifting system is disconnected from the
power supply.
- Care must be taken as burns can occur from touching hot parts.
- Prevent damage to the power feed cables on account of driving over or heavy or falling objects.
- Do not drive over interconnecting cables. Always disconnect interconnecting cables and remove from
vehicle travel path before moving vehicle.
- Do not operate equipment with a damaged cord or if the equipment has been dropped or damaged until it
has been examined by a qualified serviceman.
- In case of using one or two lifting columns (in paired operation), be sure that this will not result in stability
risks. In case of doubt, consult your superior. Unsafe lifting can result in serious injury and damage to the
lifting system and/or vehicles.
- This lifting system should only be used for lifting of vehicles and not for other applications. The positioning
of the lifting system must be done in a way that a safe working area will be obtained above and around the
lifting columns, thereby creating escape paths for emergency situations (leave passageways of at least 600
mm, 24").
- If a vehicle is in the lifted position, its air suspension system may not be used in a view of possible change of
track width and/or wheel base.
- Use the lifting columns only on a hard and level floor with sufficient bearing capacity,
see 1.2 Specifications for floor pressure and floor load.
- Once desired height has been reached, it is recommended but not required that the lift be lowered into the
mechanical locks.

3. DESCRIPTION OF THE LIFTING SYSYEM
For the hydraulic system diagram see figure K.
The mobile column lift is a movable electrically driven hydraulic column lift used for lifting heavy vehicles. At
least two lifting columns are required for lifting a vehicle. The number of lifting columns required depends on the
weight of the vehicle and the number of axles.
The main components of the mobile column lift are shown below:
Usually, a set of four lifting columns are used consisting of one primary column and three secondary columns.
The power supply is connected to the primary column. The primary column and secondary columns are
interconnected so as to form a ring circuit. All power supplies and the control signals are through the
connecting cables.
The primary column can be set to function as a secondary column when more than one primary column is used.
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 positions to the control system.
The control system controls and protects the lifting system during lifting or lowering as follows:
- At a difference in height between the lifting columns of over 5/8" mm and less than 1 1/4"mm, an
extra adjustment valve in the hydraulic system opens and remains open until the difference has been cancelled out.
Fig. 3.1
ST 1072
Each lifting column has a lifting
capacity of 16,000 lbs.
Consequently, four columns
have a total lifting capacity o
f
64,000 lbs. The total lifting
capacity can be increased by
adding lifting columns.
ST 1055
Each lifting column has a lifting
capacity of 10,000 lbs.
Consequently, four columns
have a total lifting capacity o
f
40,000 l
b
s. The total lifting
capacity can be increased by
adding lifting columns.
ST 1060
Each lifting column has a lifting
capacity of 12,000 lbs.
Consequently, four columns
have a total lifting capacity o
f
48,000 lbs. The total lifting
capacity can be increased by
adding lifting columns.

10
- At a difference in height of over 1 1/4" and less than 2 3/8", lowering is interrupted. A lifting
fork may be blocked; the cause of the failure must then be traced first. Lifting is still possible, the adjustment
valve in the hydraulic system will open and remain open until the difference has been cancelled out.
- At a difference in height of over 2 3/8" mm, the control voltage is switched off, thus blocking all
movements. The cause of the failure can then be traced.
In addition, the control system has been designed so that:
- Each lifting column can be operated separately
- Any pair of axles can be handled separately
Also see section 6, Operation
3.1 STRUCTURE OF THE COLUMN LIFT
Each lifting column consists of (see figure 3.1):
- a column and a lifting cylinder
- a hydraulic unit
- a control box
- a pallet jack lifting mechanism
- a mechanical safety lock
• Hydraulic unit
The hydraulic system consists of an electrically driven pump, flow control valves, control valves and a liquid
reservoir.
• Column and lifting cylinder
The column and lifting cylinder form the major part of the mobile column lift. In the U-section of the column
are a guide block and rollers. The rollers enable the guide block to move along the full length of the column.
The hydraulic lifting cylinder provides the lifting capacity.
• Control box
The control box has all the functions controlling the use of the lifting column. The control box of the primary
column is provided with a three-position switch allowing the lifting column to be used as a secondary column if
necessary.
The control box components and functions have been specified in sections 5 and 6.
• Pallet jack mechanism
The two-wheel pallet jack mechanism serves to move the lifting column. The two wheels protect the lifting
column from being turned over at the back when it is moved. The pallet jack mechanism lifts the back of the
column off the ground so that the column can be easily moved.
The pallet jack mechanism is operated by means of the handle bar and the handle inside the bar.
The handle can be set in three positions:
1. When the handle is set in the upper position, the pallet jack mechanism is lowered.
2. The middle setting is the neutral position; the column can be moved without the system being lifted or lowered.
3. When the handle is in the lower position, the pallet jack mechanism can be raised by moving the handle up and
down.
• Mechanical safety lock
If the hydraulic pressure fails while a vehicle is on the lifting system or is lifted or lowered,
a mechanical safety lock ensures that it cannot drop.
The characteristic clicking of the safety lock indicates that it has been activated.
During lowering the pawl is retracted by a solenoid.

11
4. INSTALLATION
Remark: Only move the lifting column with the correct type of lifting equipment.
Only raise the lifting column at the correct points. Damage to lifting column and/or injury to
persons may occur if the lifting column is not moved in the correct manner.
4.1 UNPACKING AND HANDLING THE LIFTING COLUMN
1. Transport the lifting column to the place of use.
2. Remove the cover from the crate or, when using a stand, remove the straps.
Remark: Do not stand under the lifting column when it is suspended from the lifting equipment. If it falls it
will cause serious injury.
3. Fasten a sling with a hoisting capacity of at least 480 kg (1065 lbs) around the lifting column and lift the
column from the crate (see fig. 4.1).
Fig 4.1
4. Carefully lower the lifting column to the floor.
5. Attach a hook to the lifting lug at the top of the column.
6. Lift the column to the upright position.
7. Remove the hook from the lifting lug.
8. Remove the cover from the hydraulic unit
Remove the plug from the fill opening and install the breather cap. Install the cover on the hydraulic unit.
9. Check for oil leakage.
10. Repeat the procedure for each column.

12
5. GENERAL USE
5.1 CONTROL
All functions of the lifting system are controlled from the controlpanel on the column.
There are two types of controlpanels:
- Primary column controlpanel.
- Secondary column controlpanel.
These two control boxes are pracically identical. Only the control box of a secondary column is not provided with a main
switch and a mains feed cable.
The functions of the switches on the primary control panel are described below (see Fig. 5.1).
1. Emergency release knob; Pressing this all movements (lifting or lowering) are immediately stopped.
2. Main switch; Controls the power to the lifting columns. The switch has three positions:
0 (OFF); removes electrical power from the lifting column(s)
1 (ON); switches on power to the lifting column(s);
2 (SECONDARY COLUMN); allows the primary column to be used as a secondary column, if the mobile column lift
has more than one primary column.
3. ×(UP) button; Controls the lifting of the columns.
4. Ø(DOWN) button; Controls the lowering of the columns.
5. “SET AXLE” button. This button serves to select the axle functions. These functions are descibed in paragraph 5.3.6.
6. Unlock button. This button controls, in combination with the lowering button, the lowering of the columns.
7. “SET REF” button. This button has several functions. These are descibed in paragraph 5.3.5.
8. Mains voltage indication light. This will go on when the internal control voltage relay is switched on.
Remark: The main switch is not fitted to the secondary column control box.

5.2 CONNECTING LIFTING COLUMNS
A fully closed ring circuit consists of a minimum of two and a maximum of 32 lifting columns (single phase a min.
of 2 and a max. of 4 lifting columns).
A column circuit requires at least 1 (one) primary column. The position of a primary column in a circuit is
irrelevant, but preferably should be located near the power supply. If in a column circuit there is one primary
column, this circuit is called a "set".
A set can consist of 2, 3, 4, 5 or 6 etc. up to 32 lifting columns (single phase 2, 3 or max. 4 lifting columns).
A set has a maximum lifting capacity of 40,000/48,000/64,000 lbs (this is the maximum lifting capacity of a standard
set of 4 lifting columns of 10,000/12,000/16,000 lbs each). For higher lifting capacities, "sets" are to be combined in
a column circuit as specified in the table below (also see fig. 5.2).

Primary columns are arranged in a circuit so that the weight of the load of the "set" (primary column followed by the
secondary columns up to the next primary column) does not exceed 40,000/48,000/64,000 lbs. To increase the
flexibility of a system, it is possible to select a primary column as a secondary column.
To ensure safety, each primary column is provided with a thermal relay preventing a set from being overloaded and
protecting the lifting system against power overloads.

5.3 DESCRIPTION OF THE MOBILE COLUMN LIFT SYSTEM
The mobile column lifts are designed in such a way as to offer maximum flexibility and convenience.
A lifting system can consist of a minimum of 2 and a maximum of 32 lifting columns.
The control system is equipped with the following features:
- simultaneous operation of all lifting columns
- operation of one pair of lifting columns (per vehicle axle): the so-called paired operation
- operation of one lifting column
Each lifting column is provided with these control functions without selector switches having to be set.
The control system of the mobile column lift is set-up as follows:
1. Connect the lifting columns in a full circuit as indicated in 5.2, Connecting Lifting Columns.
- The column sequence in this circuit can be selected at random; primary columns or secondary columns can be
positioned at any place, provided the maximum lifting capacity of 40,000/64,000 is not exceeded as described
in 5.2.
- A system must have at least one primary column (single phase must have at least 2 primary columns).
- The maximum number of lifting columns in a system is 32 (single phase a max. of 4 columns).
2. With respect to all primary columns:
- Eensure that the main switch is in the O (OFF) position, then connect the feed cable to the right mains
connection.
- Set the main switch to 1 (ON).
If the circuit consists of more than one primary column, ensure that all other main switches have been
set to 1(ON) or 2 (SECONDARY COLUMN).
- If the switch of another primary column has been set to 1, this column also has to be connected to the mains.
- When the column has been set to 2, it will function as a secondary column and does not need to be connected
to the mains.

3. Take care that the emergency stop button of each lifting column has been released.
4. Press the "SET REF" button.
The light in button 8 (feed) will come on indicating that:
- the system control has been checked for its proper functioning
- the sequence of all lifting columns has been stored in the system memory
- the primary column in the system has been connected to the mains.
5. Press the "SET REF" button again.
The light in this button will come on indicating that:
- the height position of each lifting column has been stored in the system.
- the lifting columns can now be activated.
All functions are possible now except paired operation.
6. Setting paired operation (only possible with an even number of lifting columns):
- Select the primary columns at one axle to set this function (e.g. the front wheel axle).
- Press the "SET AXLE" button on one of the lifting columns belonging to the selected axle for approx. 3
seconds.
- The "SET AXLE" button will flash indicating that the setting procedure has been selected.
- Within 30 seconds press the "SET AXLE" button of the control panel of the lifting column on the other side
of the axle and also keep it pressed for 3 seconds.
The "SET AXLE" buttons of all lifting columns will go on indicating that paired operation has been set.
When setting paired operation, the other pairs of axles in the control system are automatically selected as pairs.
This only works satisfactorily if all lifting columns have been connected in a closed circuit as described in 5.2.
All system functions are now available by pressing:
- button 3 ⇑, all columns are raised;
- button 4 ⇓, lowered and locked;
- buttons 6 and 4 ⇓, all columns are lowered;
- buttons 5 (SET AXLE) and 3 ⇑, one axle is raised (2 lifting columns);
- buttons 5 (SET AXLE) and 4 ⇓, one axle is lowered (2 lifting columns);
- buttons 7 (SET REF) and 3 ⇑, one column is raised;
- buttons 7 (SET REF) and 4 ⇓, one column is lowered.
