Embodiment Construction
[0030] The obliquely downward traveling direction in the present invention refers to the direction range formed by the traveling direction of the crawler working device and the direction of gravity when the crawler working device is close to the stair step (at this time, the traveling direction is horizontally forward).
[0031] see image 3According to the present invention, a step-down auxiliary mechanism 1 of a crawler-type working device includes a support member 3 that can extend obliquely below the traveling direction of the crawler-type working device body 2 . The extendable support 3 is used. On the one hand, when in use, the support 3 can be extended to reach the stair steps obliquely below the crawler-type operation device, which plays a role of supporting and buffering the crawler-type operation device, avoiding the crawler The crawler-type operating device suddenly accelerates downward to cause a rollover; on the other hand, the support member 3 can be retracted wh...
