STAIR-CLIMBING WHEELCHAIR CARRIER

An extension/retraction cylinder (5) stops or starts tilting the platform (21) of a stair-climbing wheelchair carrier (2) based on a detection signal from an inclination sensor (51) provided in a crawler drive unit (3). When the crawler drive unit (3) is detected to be not tilted, the tilting motion...

More Information
Summary:An extension/retraction cylinder (5) stops or starts tilting the platform (21) of a stair-climbing wheelchair carrier (2) based on a detection signal from an inclination sensor (51) provided in a crawler drive unit (3). When the crawler drive unit (3) is detected to be not tilted, the tilting motion of the platform (21) is stopped at an intermediate angle (e. g. 20 °) of a maximum preset angle (e. g. 40 °). When the crawler drive unit (3) is detected to be tilted, the platform (21) is tilted up to the maximum preset angle, and as soon as the crawler drive unit (3) is detected not to be tilted after tilting, the platform (21) is driven so as to decrease its inclination angle relative to the crawler drive unit (3). Thus, a comfortable and usable stair-climbing wheelchair carrier (10) can be provided.
