Lift table with quadruple scissors

This mobile lift table is not only impressive because of its four stacked scissor packages. The additional equipment and the special location of use make this project truly unique.

In our company, we regularly undertake annual maintenance of many lift tables. However, with this project, we know: None of our employees will ever see this particular lift table again.
The reason lies in its area of application. The lift table is used for the dismantling of a nuclear power plant. After its use, the scissor lift table will be irradiated, making it inaccessible for ordinary maintenance.

Tight spaces
We often recommend our clients choose a longer platform to avoid the installation of an additional scissor pack. In this case, the relatively narrow aisles forced us to go for the most compact design possible.

Reaching high working heights
Despite its compactness, the platform must be able to handle a working height of 6,400 mm. Once the platform reaches the required height, two small hydraulic cylinders extend in front, bracing against the wall. With a pulling force of up to 30 kN, a hydraulic winch pulls previously loosened components and wall segments onto the platform. These can then be safely transported downwards and disposed of properly.

In addition to the obvious features such as the sturdy chassis with heavy-duty casters, the lift table has other special features that prepare it for its use:

The winch has a pulling force of up to 30 kN and a cable length of 10 meters. It is firmly bolted to the platform, yet it offers the option for disassembly should specific operational requirements necessitate it.

The scissor lift table is equipped with four robust lifting lugs on the underframe, allowing for flexible relocation of the lift table within the nuclear power plant.

The combination of support cylinders and holding eyes ensures stable and secure positioning of the lift table during operation. The support cylinders create a counterforce to the winch, while the holding eyes reliably secure the support cylinders.

Especially at great working heights, one wants to avoid any risks. For this reason, each lifting cylinder is equipped with a lowering brake valve as well as a hydraulic locking valve. Hydraulic locking valves prevent the platform from unintentionally lowering—even in the event of a hose rupture or other leakage.
