40ft Container Loader Trailer Detailed Description
ZW Group’s 40ft container loader trailer offers a smart and efficient logistics solution for independently loading and transporting both 20ft and 40ft containers. Unlike conventional models, this trailer features a sliding side-lifter system. This system lets the front and rear cranes adjust their positions based on container length, which ensures precise alignment and smooth operation during loading.
When it comes to performance, the side-lifter arms lift up to 37 tons with the support of a powerful dual-crane hydraulic system operating at 28 MPa. The trailer rides on a high-strength chassis, reinforced by mechanical suspension and three 13-ton axles, making it ideal for heavy-duty use in ports, container yards, and construction sites.
In addition to its core strength, the trailer includes robust landing gear, six large brake chambers, and a 24V electrical system with comprehensive lighting and safety features. Furthermore, buyers can choose to purchase the trailer, sideloader, and tractor as a complete set or separately, offering flexibility in fleet planning and cost control.
As a result, operators can take full control of container handling tasks. They reduce reliance on external lifting equipment, increase efficiency, and lower labor costs—ultimately boosting productivity in diverse working environments.
