In our user manual, we recommend lowering the scissor lift table when it is not in use for an extended period. But why is this important?
Can the lift table lower uncontrollably?
The risk of an uncontrolled lowering is extremely low, if the scissor lift table is regularly maintained. Such an issue can occur, if hydraulic valves become dirty and no longer close properly.
The EN 1570-1 standard for lift tables defines clear requirements in this regard: A platform loaded with its full capacity must not lower more than 5 mm within 10 minutes. If this value is exceeded, the hydraulic valves should be cleaned or replaced.
If lowering must be completely prevented, various technical solutions are available. These include compensation controls or mechanical supports. Our team is happy to provide tailored advice to help you find the right solution for your needs.
Why should I lower my scissor lift table?
Even if there is no immediate risk of uncontrolled lowering, we recommend regularly lowering the platform — and for good reason: It helps extend the lifespan of the hydraulic components.
A key factor is the protection of the piston rods. These are safeguarded by a thin oil film that is replenished when the cylinders are retracted. However, if the platform remains in an elevated position for an extended period, the oil film can evaporate. Without this protective layer, the risk of corrosion increases, which in turn can damage the cylinder seals.
Additionally, the lowered position relieves stress on the entire hydraulic system. When the lift table is fully lowered, the operating pressure is completely released. This significantly reduces strain on components such as hoses.
What is meant by a "longer break" for a scissor lift table?
The definition of a "longer break" cannot be universally determined, as it strongly depends on individual usage conditions. However, as a guideline, a duration of approximately one week can be considered.
This means your lift table should be lowered at least once a week to preserve the hydraulic components.
