Lift tables for outdoor use

A scissor lift table used outdoors is exposed to various weather conditions that are not a factor indoors. It must be protected from rain, snow and sunlight to ensure long-term reliable operation.

Another important issue is accessibility. If the lift table is located in an unsecured area, it must be safeguarded against unauthorized access. This includes both protection from unauthorized operation and measures to prevent deliberate damage to the lift table.

Protecting the mechanics

When our lift tables are used outdoors, we don’t rely solely on a simple coating for the platform and base frame. Instead, both components are hot-dip galvanized. While a coated platform provides adequate initial corrosion protection, experience shows that the coating wears off with continuous loading and unloading. Once the bare steel is exposed, it becomes vulnerable to weather and corrosion. In contrast, a hot-dip galvanized surface is much more robust and offers long-term corrosion protection, even after years of use.

Why is the base frame also galvanized? Many lift tables used outdoors are installed in pits to allow level access, as is the case with loading lift tables. Despite existing drainage systems, blockages caused by leaves or debris can lead to standing water in the pit. To prevent damage from prolonged water contact, we also use galvanization for the base frame.

The situation is different for the scissor mechanism. Since the coating of the scissor mechanism is not subjected to wear from loading and unloading and generally does not have prolonged contact with water, galvanization is not necessary. As long as the lift table is not exposed to extreme conditions like salty sea air, a special outdoor coating provides sufficient protection. To ensure this, we seal all joints first, then prime and coat the scissor mechanism multiple times.

However, if you prefer a fully galvanized scissor lift table, we are happy to offer this option upon request.

Lift tables used outdoors are exposed to a wide range of temperatures. The biggest challenge typically comes from lower temperatures. For hydraulic lift tables in particular, it is important to use hydraulic fluid that is suitable for the specific application. To ensure smooth operation even in winter, we use low-viscosity hydraulic oil for outdoor applications. This also applies to all lubricants and mechanical bearings used.

An often overlooked aspect is the electrical wiring. Not all plastic insulation is designed for extreme temperatures, so the cables used must be appropriately rated for these conditions.

Equally important is protection from direct UV exposure. It is essential to use UV-resistant plastic sheathing.

If a scissor lift platform or goods lift is located in an unsecured, publicly accessible area, special safety measures are necessary to prevent unauthorized access. An effective method is to restrict the operation of the lifting device to those with a key.

Additionally, the lift table should always remain in its lowest position when not in use. This minimizes the risk of damage or theft, as critical components such as hydraulic cylinders, electrical sensors and the drive system with its control unit are housed beneath the platform.

A robust construction of the lift table can also help protect against deliberate damage. However, even the sturdiest design cannot guarantee complete safety. Damage to control elements or misuse of safety features, such as removable guardrails, is difficult to fully prevent.

Beyond the material damage that can result from unauthorized use, there is an even greater risk: During the lifting and lowering process of a scissor lift table, potential pinch and shear points are created. Improper handling could lead to serious injuries or even death in the worst-case scenario. Therefore, it is essential to ensure that no untrained personnel, especially children, have access to the lifting device.

Additional safety can be provided by using an RFID control system. This system evaluates an RFID chip to enable operation. The evaluation unit is located in the main control cabinet and the signals between the reader and the evaluation unit are transmitted in encrypted form. As a result, even forcibly opening the control housing would not be sufficient to manipulate the system.

In this article, we want to show you what to consider when selecting a lift table for outdoor use. Of course, you don’t have to worry about all the technical details yourself. Just let us know where and for what purpose you intend to use the lift table and we will take care of finding the right solution for your needs.
