Lift table for the Ex zone

In this article we present a lift table which is used inside a spray-painting booth, i.e. inside an Ex zone. It explains how the scissor lift table contributes to a more ergonomic workplace and consistent quality of the painting.

Place of use of the lift table

An overhead track is used to transport components in the production area of our customer. For a flawless paint job, the employees must be able to easily reach every part of the component. Unfortunately, this is difficult with the fixed height of the overhead track and the different heights of the employees.

This led to the decision to install a scissor lift in the paint shop, which allows the quick and easy adjustment of the work height. With the simple push of a button, each employee can adjust the paint system to his or her wishes or body height with minimal effort, and so achieve an ergonomic working position.
In addition, the quality of painting is improved by the use of the lift table, as even previously hard to reach areas of the component can now be painted without difficulty.

Special features

The installed lift platform is not a standard lift table as it has a number of special features. For example, no classic platform was used, but an open frame structure with an angular frame. This allows the insertion of galvanised metal plates as splash guards and exchangeable gratings.

Attention was also paid to the most cost-efficient arrangement of the components. The use of a hydraulic system made it possible to separate the drive unit from the actual lift table without any problems. This allowed the hydraulic unit and the switch box to be removed from the Ex zone. This in turn allows the use of less expensive standard components and spares the use of cost-intensive components for the potentially explosive zone. Due to the clever arrangement, only the lifting limit switch and the manual controller had to be replaced.

Apart from the actual lift table, a sloping ramp and loading flaps were also included in the scope of delivery. These were covered with an anti-slip surface made of aluminium quintet plate. They serve as ramps to access the raised lift table platform.
