A modular trailer is a series of special vehicles that is used to transport large cargos that are difficult to disassemble. The trailer is also used transport over-length goods.
The modular trailer uses a mechanical steering system. The vehicle loading platform of a modular trailer is kept at balance when transporting goods on bumpy or rough roads in a way that the damping property is excellent.
Mian components of modular trailer:
1. Frame
The frame center beam and the stable crossbeams give the frame a high degree of rigidity. Hence, the frame can achieve its optimal loading level. The frame has a reinforced loading deck, which allows extreme point loads.
The steering system, air tank, and hydraulic oil tank are all integrated into the bogie frame. Thus, the parts are protected against damage and corrosion.
2. Hydraulic wheel bogie
The modular trailer uses a hydraulic wheel bogie, which consists of the bogie frame, hydraulic cylinder, axle, tyre, and rocker arm. It has a strong load capacity.
When the road is uneven on the transverse direction, the axle swings to compensate. If the road is uneven in the driving direction, the hydraulic lifting system adjusts the modular supporting system.
The modular unit can assume 3-point or 4-point supporting system to ensure that each supporting point carries an even load.
3. Hydraulic suspension
The individual swing axles in a multi axle modular trailer consist of the hydraulic suspension, which can be connected to different support circuits.
The purpose of connecting the suspension to different circuits is to ensure that the axles have equal loads.
When the axles have equal loads, you are guaranteed of the optimal lengthwise and crosswise leveling even if you are driving on uneven terrain. The equal loads also regulate extreme cross falls.

Self propelled modular transporter application:
The major applications of modular trailers include power stations, chemical industry, iron and steel industry and the construction industry. Modular trailers are used for mining operations because of their excellent lateral stability.
1. Ship Building Industry
Ships and ship sections are normally huge and bulky. You can imagine the how the construction of the big ships you see transporting goods and people across seas is done.
SPMT trailers become very useful in the movement of ship sections to assembly halls and the entire ship to the sea. Ships are normally very heavy weighing up to thousands of tones.
The biggest ships will need self propelled modular transporter trailer with over 200 axle lines. in some occasions, the placement of the axles is done side by side to help in carrying long and wide ship sections.
The construction of bridges, large buildings and roads also require the use of modular trailers. Big bridge segments and large girders are placed onto the modular trailers from the construction sites.
Some of these modular trailers will be linked to robotic-like crane arms. These arms move the bridge sections and the huge girder sections from the transporter to the road section under construction.
Some of the construction concrete beans are too heavy to be loaded and transported on a semi-trailer. In that case, modular trailers come in handy to help in the transportation of construction materials, and equipment.
Wind energy has been embraced by many countries around the world in order to help in the conservation of the environment and its natural resources. To make this happen, very large equipment is used to facilitate the tapping of wind in order to generate the energy for transmission.
These wind energy harnessing equipment are likely to be found on mountains where the wind is very string. Getting them to such locations requires stable off-road modular trailers to safely transport them.
The multi axle modular trailer wheels designed for this application are able to navigate the roads all the way up. The axles are managed and controlled to keep balance when on such terrains.
