1. Introduction
Electric wheelchair ramp can be applied on low-floor city bus and installed underside of passenger door step. When vehicle arrives at stop, the driver control the switch, and then platform can be extended and retracted smoothly. When the platform reach working position, the rear-end of ramp will raise automatically to eliminate height of threshold of passenger door so as to ensure rear-end of platform level up to vehicle floor, convenient for wheelchair to access vehicle.
This electric wheelchair ramp has got two patents (Patent NO. ZL 02 2 83133.9 and ZL 2006 20005099.5).
2. Technical Parameter
Unit: mm
3. Technical Function
Rated Voltage of Motor: DC24V
Max. Working Voltage of Motor: DC≤31V
Max. Driving Current: 10A
Time for Retraction or Extend: 12~16S
Max Loading Capacity: 350 Kg
Max. Working Height: 300-380mm
Ramp Raising Height of Rear-end (extend fully): 55mm
