The displayed dock lift table is designed for use at a ramp and transports goods from ground to ramp level. Below are some characteristic features of the loading platform.
Embedded loading flaps in the platform
Loading flaps are a common additional feature for dock lift tables. In this case, they bridge the gap between the scissor lift table and the ramp, facilitating the loading and unloading process. The special feature of this dock lift table is the embedded loading flaps in the platform. Normally, the loading flaps are installed in front of the platform. However, in this instance, it was not possible because the pit was already existing, and the lift table had to be adjusted to fit the dimensions of the pit.
Equipped for outdoor use
Hot-dip Galvanisation for surface protection
Lift tables used outdoors are exposed to harsh weather conditions and therefore require special protection. A crucial factor is surface protection. All structural parts that come into contact with moisture for extended periods are hot-dip galvanised. This includes the railing, portal, loading flaps, platform and base frame. The scissor mechanism itself is not galvanised but is instead primed, sealed and painted. These protective measures are sufficient as the scissor mechanism is shielded from prolonged moisture by the platform, base frame and usually the lowered lift position.
IP65-rated electrical components
The electrical components must also withstand the specific demands of outdoor use. To protect these components from water, all electrical elements are designed to meet IP65 standards. Additionally, for this project, a control unit was installed on the wall inside a stainless steel enclosure. These measures prevent moisture-related damage to the electrical system.
Non-slip platform coating
For all walkable platforms, a non-slip coating is essential. Moisture and dirt significantly increase the risk of slipping on smooth surfaces. Therefore, we use chequer plate for lift tables intended for outdoor use.
Environmentally friendly hydraulic oils
Another important aspect is environmental protection. In environmentally sensitive areas, such as water protection zones, regulations often mandate the use of biodegradable hydraulic oil. Therefore, we use ester-based biodegradable oil for the hydraulic lift table. This prevents contamination of water and soil with mineral oil.
Safety features of our dock lift table
Electrically unlockable check valves
Since the dock lift table allows for the transportation of personnel, we use electrically unlockable check valves on the cylinders. These valves ensure that the platform remains securely in position in case of a leak or hose rupture, preventing uncontrolled descent. The hydraulic valves open only when an electrical voltage is applied, which is why the lift table must have an uninterruptible power supply (UPS). This ensures that employees can safely lower the platform to the lowest position even during a power outage.
PVC roll-up curtain as underrun protection
Another safety feature are the PVC roll-up curtains that act as underrun protection. They prevent people or objects from entering the hazardous area beneath the platform.
Removable side railings
The side railings of the dock lift table are removable, allowing trucks to drive over the platform when it is in the lowered position. To ensure that no one falls off the platform during operation, the railings must always be in place once the dock lift table leaves the lowest position. Therefore, the railings are electrically monitored.
Electrically monitored crossbar
The crossbar of the portal serves as a fall protection measure at the upper stop and can be removed for loading operations. The crossbar is also electrically monitored to ensure it is always correctly in place before the platform is operated.
Additional features for the dock lift table
Foot controls for comfortable operation
To make the loading and unloading processes as convenient as possible for the employees, our customer opted for a foot control. This control is embedded directly in the platform under a cover and feature an up/down button as well as an emergency stop button.
Overload measurement for damage protection
Continuous overloading of the dock lift table can cause mechanical damage. Therefore, overload measurements are conducted to protect the lift table from being overloaded. The overload measurement system is linked to a horn and a signal lamp, providing immediate auditory and visual warnings to the operator when the lift table is overloaded.
