OVERVIEW OF THE FUNCTIONS OF THE DELTA
3.1
Safety devices
The Delta platform lift is equipped with the following safety devices:
3.1.1
Platform barriers and ramps
The barriers and ramps, which must be closed (horizontally) or folded up during the drive, prevent
a fall forward or backward. These always open automatically at the stops if the travel command is
pressed.
3.1.2
Safety bottom
The safety bottom is attached to the underside of the platform and serves as additional safety. It
reacts to pressure so that the system stops immediately if the safety bottom hits an obstacle. The
travel command in upward direction remains active.
3.1.3
Lateral contact bars
Contact bars are fitted to the side of the platform wall to prevent jamming in the direction of travel.
The travel command in the opposite direction remains active.
3.1.4
Overload device
The platform is equipped with an overload device. If the load capacity indicated on the type plate is
exceeded by more than 25%, an overload switch switches off the system and an acoustic signal
sounds as well as the overload indicator on the platform display. In this condition, it is not possible
to drive on.
The platform must never be overloaded. If an overload is signalled, the loading must be
reduced immediately.
3.1.5
Emergency stop
The Delta platform lift is equipped with an emergency stop button. If you need to stop the platform
in an emergency, press the red button and the lift stops. Unlocking is done by pressing it again or
turning it clockwise.
3.1.6
Alarm button
The platform is equipped with an alarm button to summon help. By pressing the alarm button, a
loud emergency signal sounds.
3.1.7
Overspeed governor and safety gear
The Delta platform lift is equipped with a speed limiter and a safety catch. If the platform moves
downwards at an increased speed (e.g., due to a defect or similar), the increased speed is
immediately detected by the overspeed governor and the safety gear is triggered. The safety gear
brings the platform to a standstill by holding it on the rails. This prevents the platform from falling.
