Why is a tandem lift table used in some cases, even though a single scissor lift seems cheaper and simpler at first glance?
This reference shows why the tandem solution makes sense in certain applications, both technically and economically.
Reasons for using the tandem scissor
In theory, relatively short single scissors would have been sufficient for the required lift (see also our article How high can a lift table raise?). However, these would only support part of the platform – the overhangs would be too large, which would compromise stability.
Longer scissors would therefore be necessary to support the platform safely.
However, due to the resulting lever arm ratios, a significantly larger series would have to be used in this case – a significant increase in cost.
The more economical alternative: a tandem lift table with two smaller scissor packages.
This allows the platform to be supported evenly over its entire length – with a smaller series and lower costs.
How is synchronisation ensured with this tandem lift table?
Hydraulic systems naturally follow the path of least resistance. With uneven loads, this means that the less loaded scissor lift rises first.
The result? A jerky, uneven lifting movement.
To avoid this problem, we use a static flow divider for tandem lift tables with uneven loads.
This ensures that, regardless of the load distribution, both cylinders receive exactly the same amount of oil – and thus extend synchronously and smoothly.
This allows us to achieve reliable synchronization without complex control technology.
Customized adjustments for this tandem lift table
Paint finish according to customer requirements
As the saying went back then: “The customer can have any color they want, as long as it's black.” Those days are over. We offer our customers a free choice of colors within the RAL color scale – with the exception of fluorescent colors. This makes it easy to adapt the lift table to the appearance of existing systems or safety concepts.
Terminal strip instead of control system
This lift table was delivered without its own intelligence. All necessary sensors and actuators are present, but control is via the customer's higher-level system control. A simple terminal strip serves as the interface, which makes integration into existing systems flexible.
Weld-on plates for customer-side assembly
The platform is equipped with ten weld-on plates to which the customer's driven roller conveyor was mounted.
Location: Belgium
The lift table was delivered to our neighbors in Belgium – more precisely, to the Flemish-speaking part of the country. Naturally, the documentation and signage were provided entirely in Flemish.
