1. Product Description
The three-axle side-lift self-loading & unloading semi-trailer integrates a high-strength hydraulic side-lifting crane mechanism and an extendable lengthened frame system. It requires no external lifting equipment such as reach stackers, forklifts or gantry cranes throughout operation. A single driver can independently complete the full set of container handling procedures including lifting, positioning, lowering and locking via wireless remote control.
Equipped with a telescopic locking structure, the frame allows flexible length adjustment. In standard configuration, it fits 20ft standard containers. When extended to 14 meters, it stably carries large-size 40GP/40HQ containers, enabling one trailer to accommodate the two mainstream container types.
It handles short-distance distribution and urban-rural feeder transport for small-batch 20ft containers, as well as long-distance trunk freight with fully loaded 40ft large containers. There is no need to purchase two separate skeleton trailers of different specifications, greatly cutting costs for vehicle procurement, maintenance and fleet dispatching, and minimizing the average freight cost per container.
Combining lifting, transit and load-bearing functions in one unit, this all-in-one container turnover transport equipment serves diverse scenarios: inland logistics parks, port feeder routes, rail-road intermodal transfer stations, mine and infrastructure construction sites, border land transport ports, emergency shelter deployment, energy storage equipment container transit, and more. It operates efficiently even in open field sites without heavy lifting machinery or narrow factory lanes.

3. Advantages
Dual-size loading cuts freight costs significantlyIt steadily carries 20ft containers for small-batch short-distance deliveries. Extend the frame to 14 meters to load full-size 40ft containers. No need to buy separate 20ft and 40ft skeleton trailers, saving spending on purchase, inspection, maintenance and driver arrangement. Fully loaded 40ft transport maximizes space usage and slashes unit shipping cost.
Built-in side lift, no external lifting equipment neededFoldable hydraulic side crane equipped. One driver operates loading/unloading & locking via wireless remote in only 2–3 minutes. Works independently at remote construction sites, rural yards, border ports and temporary shelters without cranes or forklifts, eliminating rental and extra labor fees.
Great site adaptability for wide transport scenariosSide lifting takes little horizontal space, performing smoothly in narrow factories, lanes and rail transfer points. Supports highway long-haul, truck-to-truck & rail intermodal container transfer. Ideal for port shuttles, mine equipment boxes, energy storage cabins, emergency supplies and cross-border land freight.
High asset utilization, usable as standard empty trailerFold the lifting arm completely, and it acts as a regular container skeleton semi-trailer for empty long-distance runs with zero idle time. This unit combines three roles: lifting machine, 20ft hauler and 40ft hauler, bringing far higher return than single-function trailers.
