6. Conformity with the product
The TW 242 GE 2-post lift is CE-certified and complies with the Machinery Directive 2006/42/EC and fulfils the
standards EN 1493:2022, EN 60204-1:2018 (see under: EU Declaration of Conformity, at the end of the
instructions for use).
7. Technical specification
7.1 General technical description
This lift consists of columns, a carriage, lifting arms, cylinders, a motor unit and other components. It is
driven by an electro-hydraulic system. A gear pump delivers hydraulic oil to the oil cylinders and pushes the
pistons upwards. The moving piston sets the chain in motion, which raises both the trolley and the lifting
arms. During the lifting process, the safety pawl automatically and safely engages with the safety toothed
block in the columns. This prevents slipping in the event of a hydraulic system failure.

8. Installation
8.1 Before installation
8.1.1 Tools and equipment required:
⋅Appropriate equipment
⋅Hydraulic oil HLP32
⋅Impact drill
⋅Spanner attachments and open-end spanners, a set of Allen keys,
Phillips and slotted screwdriver
⋅Hammer, pincers, 17 mm, 19 mm, 22 mm socket spanner
8.1.2 Checklist (packing list)
Unpack all parts and use Appendix 1 to check that each part is present. Do not hesitate to contact us if any
parts are missing.
8.1.3 Soil conditions and foundation
The lift should be
installed on a smooth and solid floor with a compressive strength of more than 3 kg/mm²,
a flatness of less than 5 mm and a minimum thickness of 200 mm.
In addition, a new concrete floor must rest for at least 28 days before a lifting platform can be installed.
(See Appendix 2 for further information)
8.2 Precautions before installation
8.2.1 Check that both columns are parallel to each other and vertical to the floor. Do not tilt.
8.2.2 Check all hoses and connections.
The lift may only be put into operation if there are no leaks.
8.2.3 All screws must be screwed tight.
8.2.4 Do not place any vehicle on the lifting platform during a test run.

8.3 Structure
Step 1: Remove the packaging and take out the box containing the individual parts and cover plates.
Read and understand the operating instructions before proceeding.
Step 2: Firstly, place a support between the two posts or lift one of the two posts using a suitably
secure lifting device, then remove the screws from the frame. Draw the outline of the base
plate on the floor with chalk and determine the position for the post.
Caution: Please take particular care to ensure that the column cannot fall down.
The accessories could be damaged or people could be injured.
Step 3: After you have removed the first pillar, place a support under the other pillar. Then also
remove the screws from the frame.
Step 4: Set up both columns. Align the main and secondary pillars at a distance of approx. 2500 mm
(inside of the pillars).
1. After unpacking, you must decide which side you want to place the main column on.
(the power connection and the control unit must be mounted on this). Set up the main
column, place the floor cover plate on this column and determine the exact distance by
erecting the second column and placing it on the second side of the floor cover plate.
2. During the installation process, it is imperative that you ensure that none of the columns
can tip over.
3. drill the holes in the floor for each floor anchor using a suitable percussion drill. Drill
vertically. Carefully remove dirt and dust after drilling and make sure that the posts remain
on the circle previously drawn with chalk.

Step 5: Attach the mechanical safety interlocks, and electromagnets, two to each column.
Step 6: Attach the base plate. Raise the two carriages by hand approx. 800 mm from the ground to lock
them with safety latches and then place the base plate between two base plates of the columns.

Step 7: Install the steel cables.
1. Align the carriages on both sides approx. 800 mm above the floor.
2. Ensure that the safety catches on both columns are engaged
before attempting to connect the ropes.
3. the slides must be level with the ground before proceeding.
4. Pull in the steel cables as shown in the illustration.
5. The steel cables must be set "taut" on both sides. Ensure that
the sound of the safety latches can be heard equally on the right and left when lifting.
6. The ropes must be secured (countered) and oiled.

Step 15: Test run.
1. Follow the operating instructions and ensure that no vehicle is on the lift during a test run.
no vehicle may be on the lift during a test run.
2. check the condition of all connections.
Attention:
Please ensure that the support arms are swivelled in / folded inwards to prevent collision with the oil
tank.
