Whenever very long platforms meet a short effective stroke, this literally screams for a tandem lift table.
Depending on the operating conditions, a solution with two horizontally arranged scissors can be more favourable than a lift table with single scissors.
Fall protection on the lift table platform
When you look at the images below, you will certainly notice that the tandem lift table only has additional safety features on the two narrow sides.
The one side has an electromechanically locked door and a corrugated wire-mesh screen, while the other side is equipped with a gantry.
The two long sides did not need additional safety equipment, as the scissor lift table runs between two walls, thus preventing a fall from the long sides of the platform. The walls also prevent access underneath the platform, so that no barrier need to be provided here either.
Access door and lowering limit switch
The access door on the platform is connected to the lift table's lowering limit switch. This means that the door can only be opened when the lift table is in the bottom position. This prevents a fall from the platform.
Falling from the top landing
Falling from the top landing poses another possible danger. Someone could fall down onto the platform when the scissor lift is not at the top.
It would certainly be possible to provide an electromechanical barrier here as well. However, up to a certain fall height, a gantry may also be used as a safety measure. The big advantage? You save on the entire electrical system as well as an elaborate mechanical system. This makes the gantry solution more cost-effective than an electromechanical solution.
Other special features
To avoid this becoming an endlessly long text, I will only briefly list the other special features and explain why we have chosen this solution.
Hot-dip galvanised platform
This lift table is constantly driven over for loading and unloading. Of course, the platform could simply have been painted, but the paint would probably flake off after a few years. With a galvanised lift table, you will still enjoy our scissor lift tables even after several years of use.
Compression and rebound when the load is transferred
Hydraulic systems have a tendency to compress and rebound when the load is transferred. To keep this as low as possible, we let the lift table move to maximum pressure in the top position. This keeps the pressure difference and consequently the compression and rebound during load transfer to a minimum.
