With the development of the transportation industry, the production of Container Semi-trailers as a container carrier continues to grow. The vehicle frame bears vibration and noise from the drive train and suspension, which are directly related to the vehicle’s control, safety and comfort. In particular, the truck frame, as an important load-bearing component, is prone to breakage. Therefore, after meeting the strength and stiffness requirements, the frame should also have reasonable dynamics. The skeleton container semi-trailer is one type of container transport semi-Trailer Frame, and the other is the flat type. The skeleton type vehicle is welded by longitudinal beams, cross beams and front and rear end beams. The longitudinal beams are made of 16Mn steel plates submerged arc welded into an I-shape (the main sizes are 450 and 500). The cross beams are stamped into grooves using steel plates. The front and rear end beams are Welded rectangular section. An integral long beam is installed at the middle container locking device to improve the load-bearing capacity of the container locking device.
The difference between a skeleton semi-trailer and a low-bed semi-trailer is that the flat-bed semi-trailer has a frame and a patterned floor. The frame of the wooden series container transport semi-trailer is all shot blasted. The entire frame is assembled and welded on a special positioning stand. It has a reasonable structure, high strength and beautiful appearance. A container compression device is installed on the frame. The four container compression devices at the front and rear ends are of a fixed structure, and the middle container compression device is of a hideable structure. When loading containers, the intermediate container locking device can be lowered below the cargo platform level as needed.
Features of the frame semi-trailer: A container compression device is installed on the frame, which can load two standard containers of 40 feet and 20 feet. The four container compression devices at the front and rear ends are of fixed structure, and the middle container compression device is of hideable structure.
When loading containers, the intermediate container locking device can be lowered below the cargo platform level as needed. Mechanical load-bearing devices are selected, mainly including Baohua 12T, 20T; Fuhua 13T; JOST; and other types.
The purpose of the skeleton semi-trailer: Its function is to support the ground and bear the front load of the semi-trailer when the traction device is detached from the trailer. There are two types of support devices: single-action type and linkage type. They are mainly composed of a support plate, a screw transmission mechanism, a reduction gearbox and a control handle. There are three types of suspension devices: single-axis suspension, dual-axis suspension and three-axis suspension. The semi-trailer is equipped with two pairs of spare tire racks, which are installed on the left and right sides of the trailer frame respectively, and are equipped with spare tire lifters.
