How to successfully install a scissor lift table

Proper preparation is crucial for efficient assembly. Therefore, before starting the installation, ensure you have the following tools and equipment ready:

• Forklift, telehandler or another suitable lifting device
• Power tools, if the power supply still needs to be established
• Spirit level for precise alignment of the base frame
• Open-end wrench set for adjusting the upper end stop
• Hammer drill, including appropriate drill bits for fastening with expansion or adhesive anchors
• Club hammer for inserting the dowels
• Small hydraulic jack for lifting the base frame
• Pry bar for shifting and precisely aligning the base frame

After receiving and unpacking the scissor lift table, transport it directly to the designated installation site.

At the installation site:

• The transport mounts are no longer needed.
  Therefore, remove the eye bolts, including the threaded rods, from the platform.

To operate the scissor lift table, the power supply must first be established.

Connection via CEE plug

As a standard, our lift tables are delivered with a CEE plug. Establishing the power supply is quick and easy:

1. Remove the cable ties from the connection cable.
2. Insert the CEE plug into the appropriate on-site socket.

Alternative: Connection via main switch

If the power supply is not to be established via a CEE plug, the lift table's supply line can be connected to a main switch. The following points are important:

• Either a main switch or a plug connection must be used.
• Direct connection to a sub-distribution panel is not permitted, as this would not allow for safely disconnecting the power to prevent accidental reactivation during maintenance or repairs.

Safety instructions for on-site power supply

The on-site power supply must be protected on all poles and equipped with an appropriate pre-fuse.

What does "all-pole" mean?
In case of a fault, not only the defective phase is disconnected, but all live phases. This prevents the electric motor from continuing to run on two phases and getting damaged.

What type of pre-fuse is required?
The exact type of pre-fuse can be found on the second page of the supplied wiring diagram, next to the network connection specifications (e.g. LS 3P C16A for a circuit breaker with all-pole 16 A protection and tripping characteristic C).

Once the power supply has been ensured, the lift table platform can be raised by pressing the button.

ℹ️ Tip: If the platform does not lift within 10 seconds, even though the motor is running, a phase rotation error may be present. In this case, two phases of the power supply must be swapped.

Next, the platform must be secured against unintentional lowering. Depending on the size of the scissor lift table, it is equipped with either two or four tubular maintenance supports:

• The longer maintenance supports are placed on the designated brackets near the fixed bearing.
• The shorter maintenance supports are positioned in the area of the floating bearing.

A stable foundation is crucial — not just for house construction, but also for scissor lift tables. The base frame must be leveled to ensure the lift moves vertically and not at an angle.

The key reference points for alignment are the running surfaces of the floating bearings and the support surface of the fixed bearing:

1. A spirit level is placed on the L-profile of the base frame.
2. The base frame is horizontally aligned using the six adjustable leveling feet.
3. The slope between the two L-profiles is also checked to ensure that the lift table does not tilt forward or backward when lifting or lowering.

Additional measures for larger lift tables

For larger scissor lift platforms, significant forces act on the L-profile. Therefore, in addition to the adjustable leveling feet, these models are also equipped with grub screws at the upper end stop. These can also be used for fine-tuning the alignment of the base frame.

Once the base frame has been aligned, it is necessary to ensure proper force distribution into the ground. For this, the bearing surfaces of the scissor lift table must be fully shimmed:

1. Place shim plates of the required height and quantity under both floating bearing running surfaces.
2. Also, place shim plates under both fixed bearings of the scissor lift table.
3. Ensure that the shim plates are evenly distributed to provide a stable support surface.

Once the base frame has been aligned, the hydraulic lift table must be securely fastened to prevent any movement. For this, expansion anchors or adhesive anchors (included in the delivery) are used.

To simplify this step, the holes in the base frame are pre-drilled to allow the drill bit to pass through directly.

• Drill four holes through the base frame into the floor using a hammer drill. Ensure that you follow the required drill hole diameter and minimum drilling depth.
• Anchoring with adhesive anchors:Fill the sleeves with adhesive. Insert the anchor into the drill hole. Allow the required curing time before tightening the anchor.
• Anchoring with expansion anchors: Insert the anchor into the drill hole. Tighten the anchor immediately.
• Final check: Ensure that all anchors are firmly in place before putting the lift table into operation.

1. Loosen the lock nuts on both screws.
2. Carefully turn the screws outward until they touch the floating bearing roller.
3. Tighten the lock nuts again to secure the position.

⚠️ Important: The screws should only gently touch the floating bearing roller. The adjustment must not be done by measuring or slowly shifting the screws via the thread.
Otherwise, the stop may be set unevenly, which could cause skewing forces when reaching the upper lift position. This could lead to excessive stress on components and, in the worst case, component failure.

Adjusting the lift limit switch

Once the mechanical stop has been correctly adjusted, the control system must be informed when the upper stop position is reached so that the hydraulic unit shuts off. This is done via the lift limit switch, which is usually located below the platform and triggers either against the scissor mechanism or the floating bearing roller. Loosen the screw on the limit switch carriage, then proceed as follows:

Roller lever switch variant

Move the limit switch from the upper stop position toward the front side, starting from the center of the platform, until the roller lever switch makes contact with the scissor mechanism. You will recognize the correct position by a clicking sound.

RFID sensor variant

Move the limit switch from the upper stop position toward the scissor mechanism. The correct position is reached once the orange status light on the sensor illuminates.
