Manual wheelchair ramp can be applied for low-floor city bus, and it is installed under the side of passenger door’ step. When the bus arrives at bus station, the driver unlocks the front cover and pulls the platform of the ramp out. After the platform reaches final position, rear-end of the ramp will be raised to eliminate height of threshold of passenger door so as to ensure rear-end of the platform level up to the bus floor, convenient for wheelchair to access the bus. After the wheelchair gets on the bus, retract the platform manually.

The manual wheelchair ramp is fixed with the frame under the floor of the passenger door by 4 brackets. These brackets are composed of 16 bolts (M10*20) and nuts and spring washers and flat washers (the diameter is 10mm).

Because the bracket connects with the frame of manual wheelchair ramp by swallow - trough, we can adjust the front and the rear position of brackets to make the front end of the manual wheelchair ramp exceed the front end of passenger door threshold 10mm. When the rear end of ramp extend fully and be raised, the ramp should be locked.
