Description

Technical Field

[0001] The utility model relates to the field of railway rescue, in particular to a road-rail dual-purpose transport vehicle. Background Art

[0002] In railway rescue accidents, the on-site conditions are complex and the railway rescue train cannot drive to the rescue site. Rescue equipment can only be manually transported from the railway rescue train to the rescue site. If the adjacent railway line cannot be used or the accident occurs in a bridge, culvert or tunnel, the manual transportation distance will be longer, even up to several kilometers, and multiple transportations are required. During the rescue process, the best way to transport is to use the existing tracks for transportation. In the past, most transportation methods involved manually pushing the vehicle body for transportation, or using the existing gasoline-powered hydraulic pump station to drive the hydraulic motor on the transport vehicle for transportation. The former increases the labor intensity of personnel and has limited operating speed. Utility Model Content
