This work lift table is something special: from its high load capacity in a small space to the well-thought-out extras — it truly is a valuable helper.
Why a 9,000-kg lift table for a 5,000-kg load?
A first glance at the scissors leaves no doubt: here stands a massive scissor lift table, built for high load capacities. The datasheet reveals that the table has a payload of 5 tons. However, that's only half the truth. The nominal load capacity is 9,000 kg!
It may initially seem odd that we use a lift table with a nominal load capacity of 9,000 kg for a 5,000 kg load, but the explanation is quite simple. The nominal load of a lift table always refers to an evenly distributed load (see our article: 'How much can a 1,000-kg scissor lift table carry?'). Our client uses the lift table to repair heavy injection molding tools. To facilitate easy handling, these tools must be flexibly positioned on the work surface. Therefore, it is possible that the 5,000 kg load might act unfavorably (e.g., eccentrically on one long side) and necessitate the higher load capacity.
The hidden helper: Optimizing workspaces for increased efficiency
When redesigning workspaces, it makes sense to review work processes. This offers the opportunity to identify hidden potentials and optimize workflows. Our client has given this considerable thought. At the end of the process, a customized solution was developed that is precisely tailored to the needs and workflows of the client:
Solid down to the smallest detail
We have already reported on the sturdy base. What may be less noticeable is the solid worktop. It is 20 mm thick, ensuring that it does not deform or suffer similar damage under heavy loads, guaranteeing years of reliability.
But why is the platform surface uncoated? Injection molding tools are precision tools. Even minor contaminants can lead to problems in later production. To prevent foreign particles from reaching the precision tools through potentially scratched paint, the table surface was only blasted and not painted.
The platform opening
Some of the injection molding tools being processed feature a long channel. Since this channel cannot bear the entire load of the tool, the old workbenches required underpinning of the tools.
To simplify this process, we created a precise pass-through in the platform. Through an opening with a diameter of 100 mm, the tool can be positioned directly without the need for underpinning. This saves the worker a step and allows them to start working immediately. Another nice side effect: Since the injection molding tool rests fully through the opening, the risk of damage to the tool is reduced.
Comfortable & still safe
To improve ergonomics at the workplace, we installed a 230-V socket and an air pressure connection at each corner of the platform. This arrangement prevents employees from having to bend unnecessarily, making the work significantly more comfortable.
A particular challenge was the placement of the connections on the sides: since the underside of the platform is secured by a foot protection rail, the openings in the side plates of the platform potentially create dangerous shear and pinch points. Our solution: The connections are hidden behind a flap, which is monitored by an electrical sensor. Thus, a lifting movement is only possible when the flap is closed.
It is also noteworthy that the lift table is raised, although the length of the scissors would have easily sufficed for the desired lifting height. This elevation is not for increasing the construction height or allowing access with an electric high lift truck. Its sole purpose is to improve working conditions: it creates sufficient space for employees' feet, enabling a more comfortable and healthier working method.
