Underflow protection for lifting tables

Bellows as underflow protection on a loading lifting table.

Hydraulic scissor lift tables are always equipped with a circumferential safety strip. This prevents anyone from getting crushed in the area of the platform edge when driving down. As soon as this bar detects a contact, it stays lifting table stand.

If this protection is not sufficient, our countless other versions can be used. These not only protect the operator, but also the lifting table itself from environmental influences or contamination. Depending on the application or official requirements, we use either Protective roller blind, a Grid shirt or one Bellows under the lifting table platform.

For many lifting table models, it is important to communicate your requirements when ordering for the first time, as more space is required between the platform and the scissors. On some models it is easy to retrofit an underflow protection, but on some it is no longer possible. 

Types of underflow protection on scissor lift tables

Stable loading lift table with PVC roller blind

PVC roller blinds are most often used to protect the lifting area. These are attached under the platform and to the floor or base frame and roll up or down during the lifting movement.

Roller blinds can be attached to individual pages or only to certain areas of the platform. For maintenance purposes you can simply step between two elements.

Grid shirt as underflow protection

Instead of a PVC roller blind you can also Protective grille - so-called Grid shirts – be used. The function is similar to that of the roller blinds. The difference is that the mesh shirt does not roll up, but rather lies in folds in the pit.

The disadvantage is that if the pit is damaged or heavily soiled, it can get caught or unevenly placed.
The advantage is that these are more robust than roller blinds.

As with all protective devices under the platform, it is always better if they are ordered when the new system is installed. A Subsequent installation of a protective grille under the lifting table platform is possible, but always involves greater effort. It can also happen that the space required is not enough.

We plan every lifting table project carefully together with our customers so that all safety components are always installed in advance according to the standard.

Lifting table with bellows

The Bellows protect the lifting table best because it is closed on all sides. This ideally prevents dirt or dust from getting under the lifting table.
With roller blinds you have e.g. B. always columns between the individual elements.

A Bellows can be installed later is very complicated because you have to put it over the platform.

During maintenance, the bellows must either be lifted or dismantled, which is slightly more effort.


Lifting table with sheet metal cladding

If lifting tables are installed in a pit and there is no space for other safeguards such as: B. the safety bar is present, then mudguards are used.
The lifting table is placed in the pit and moves up 600mm, but the sheet is 700mm long and therefore always protrudes into the pit. This prevents there being a gap between the raising platform and the floor and prevents anyone from squeezing.
Sheet metal is very stable and safe, but a very deep pit is also necessary, so this protection is rarely used.
