Chassis lifting transport trailer is a multi-purpose transport equipment developed by Zoomye Company to solve the problem of slow transition and difficult loading and unloading of farm crawler type equipment (crawler orchard management machine, crawler lawn mower, crawler excavator, crawler type pesticide sprayer, crawler type operation platform, etc.). It can flexibly load and unload various materials without forklift assistance. The trailer axle can be lifted and lowered under the action of the hydraulic cylinder (the lifting range can be customized), and the tail of the trunk bottom plate can fit perfectly with the ground under the action of the cylinder, forming a small included angle with the ground, which is convenient for the crawler type equipment to move up and down freely. Other wheeled equipment, fruit baskets, materials, etc. can also be loaded and unloaded freely through the trailer without forklift assistance.
