The XINDER electric wheelchair ramp has gained the Chinese paten (the number of the paten: Zl 02 2 83133.9). The products has the running test of extending and retracting 10000 times continually, and been proved with good reliability and safety.
B. ADVANTAGES
C. SAFETY FUNCTION
B. ADVANTAGES
¨ Be made of stainless steel, aluminum alloy and aluminum honeycomb.
¨ it extents and retracts steadily
¨ It is light and anti-corrosive.
¨ the computer program and the proximity sensor can realize the customizable electronic control
¨ EMC tested in accordance with 95/94 standards.
¨ Unique patent, super thin (60mm), super light (45Kg)
¨ Unique double hinged mechanism for lifting rear-end of ramp can eliminate height of threshold of passenger door, thus ramp can installed underside of passenger door step and that won’t weaken strength of skeleton near door, convenient for wheelchair to access vehicle
¨ Intelligent control by computer program and non-contact access switch, retract automatically in case contact obstruction and also interlocked with passenger door
¨ Electric driven device achieve ramp smoothly extended and retracted
¨ Manufactured by stainless steel and aluminum alloy, honeycomb aluminum plate. With superexcellent performance of anti-corrosion.
C. SAFETY FUNCTION
Ø Adopt anti-skid aluminum plate on the surface of platform
Ø With sound and flashlight alarm during operation of wheelchair ramp
Ø With danger symbol on the outer-edge of ramp
Ø The ramp is interlocked with passenger door.
D. MANUAL FUNCTION
Ø When the driving motor is invalid, the ramp can be retracted manually.
In the course of the ramp extends, if it touches any barrier, the ramp will retract automatically. For a moment, it will extend again. If this status repeats 3 times, then the ramp retracts to the rest position for safety.E. TECHNICAL SPERCIFICATION
