Janzen Lifttechnik designed and manufactured a lifting platform for a public facility, enabling wheelchair users to move between two building levels. In addition to safe passenger transport, ensuring that the platform blended in with the existing surroundings was an important consideration.
Safety Features
As the scissor lift platform is designed to transport wheelchair users, it is equipped with additional safety features. These include emergency lowering in the event of a power failure, overload monitoring and protection provided by an enclosed lift shaft.
Controlled Lowering in the Event of a Power Failure
The lifting platform is equipped with an uninterruptible power supply (UPS). This allows the electrically operated pilot-operated check valves to be activated even during a power failure, enabling the platform to be lowered in a controlled manner.
Overload Monitoring
Overload protection is provided by hydraulic and electronic components. In the lower position, a pressure relief valve prevents the platform from being raised if it is overloaded.
In the upper position, an electronic pressure switch monitors the pressure in the hydraulic system. If the set limit is exceeded, platform movement is prevented and a warning is displayed to the operat
Enclosed Lift Shaft Instead of a Foot Safety Edge
A foot safety edge was not required for this installation, as the hazardous area beneath the platform is protected by an enclosed lift shaft structure.
Documentation in the Inspection Logbook
The lifting platform is supplied with an inspection logbook in which all inspections and maintenance work are recorded. This provides evidence of the system's regular inspection and maintenance.
Additional Features of the Lift Table
Compensation for Construction Tolerances
To compensate for common construction tolerances, the lift table is equipped with suitable adjustment mechanisms. Support bolts and adjustable levelling feet on the base frame allow the lower stop to be adjusted. An upper end stop and a limit switch ensure that the platform is also positioned precisely at the upper stop.
Platform with a Stainless Steel Border
In addition to functionality, ensuring that the lift table blended in with the existing surroundings was an important consideration. The platform features a stainless steel border around its perimeter and can be fitted with the same flooring as the adjacent areas. This allows the lift table to blend discreetly into its surroundings.
