Modular Trailer

Modular trailers for heavy equipment are normally used for transporting heavy loads over 80t. The transporting heavy loads are generally applicable to the medium and long-distance highway transportation of overweight and ODC cargo (over length, over width, over height, overweight) in construction, mining, metallurgy, chemical industry, thermal power equipment, power station construction, heavy machinery manufacturing, oil gas field, bridge, loading and offloading operation, railway construction, and other industries. 

Modular trailer for sale is mainly composed of box shape center frame, hydraulic suspension, axle, steering system, hydraulic system, air braking system, power pack, and other components.  The modular trailer has the advantages of adjustable platform height, uniform axle load, less turning radius, and so on.

How is a Modular Trailer Different from a Traditional Flatbed Trailer?

A modular trailer is different from a traditional flatbed trailer in several ways.

Firstly, a trailer modular can be configured in different combinations by adding or removing modules to meet the specific requirements of the load being transported, whereas a traditional flatbed trailer has a fixed size and configuration.

Secondly, modular trailers are typically designed to carry heavier loads and have a higher load capacity than traditional flatbed trailers.

Finally, modular trailers are more maneuverable than flatbed trailers and can navigate through tighter spaces and around obstacles with greater ease, making them ideal for transporting oversized and overweight loads in difficult terrain.

Modular Trailer Key Features

Modular Trailer Key Features

  • The frame splicing surface is processed by gantry milling, with a more accurate size and no gap on the frame splicing surface.

  • The side of the frame adopts a Goldhofer shape, which is more beautiful and atmospheric.

  • The laser hollowed-out mark at the pipeline connection is convenient for customers to plug in the hose and is durable.

  • The frame pipeline is optimized, and all pipelines adopt full-automatic NC elbow to ensure the consistency of pipelines.

  • The operation box is optimized, which is more beautiful, and the pressure value is more convenient to view. All the inside of the operation box is hard pipes Marked with the interface.

  • The steering cylinder and suspension cylinder are all Hengli, which is more reliable and durable.

  • All hydraulic hoses adopt the American imported brand Eton.

  • The modular trailer adopts two-color spraying, gray inside and red outside. At present, only the SPMT module is sprayed according to this standard.

  • The tail adopts the form of an integral anti-collision beam, and an integrated tail lamp, and the hose can be hidden, which is more beautiful and optional.

  • All bolt pins are galvanized parts, which are not easy to rust.

  • The gooseneck adds a high-pressure accumulator to better protect the steering pipeline.

  •  Powerpack upgrade:

    ① add the air pump.

    ② The hydraulic pump is a high-pressure inclined shaft pump, which is more durable.

    ③ The battery voltage is 24 V, which is more suitable for low-temperature working conditions.

  • The steering system is optimized, the steering is more accurate, and the steering dead center and other problems are solved.

  • The gooseneck is equipped with an external operation box, which can control the lifting of the rear two points, and the gooseneck + single-vehicle mode is more convenient.



A modular Trailer is a piece of special heavy-duty trailer widely used for special transportation of ODC cargo, such as infrastructure, power stations, and oil and gas fields. It adopts the most advanced design in the world, with light dead weight, extra heavy load capacity, wide application range, reliability, and durability. Modular design is adopted, which can be combined horizontally and vertically; module with 2 ~ 7 axles of a single unit. The combined loading capacity ranges from 50 tons to 3500 tons. The greatest advantage of this series of trailer modular is the possibility of multiple combinations. For large and medium-sized goods with high heights, multiple modular loading platforms can be used for horizontal and vertical slicing. Users can make corresponding combinations according to different weights, lengths, and widths of goods, so as to meet the requirements of goods transportation, reduce transportation costs and shorten the transportation cycle, such as equipped with customized turntables and drop decks, trailer modular can be expanded into the flexible trailer and drop deck trailer to transport ultra-long structure and ultra-high goods.




What is the difference between a modular trailer and a self propelled trailer?


Based on the structure of the modular trailer, SPMT is equipped with a power system, and each suspension is changed to an independent suspension. Standardize and modularize the structure shape, and continuously splice the module according to the quality of goods. It integrates computer and micro-electric technology, hydraulic technology, and wireless communication technology to realize wireless intelligent operation.


Can modular trailers be customized?


Yes, for sure. Modular trailers for heavy equipment can be customized. it can be designed to transport different cargo with its special size. ..., also can meet client needs to make different sizes of the module, to achieve the best solution for transport needs.


What is a modular trailer?


Modular trailer have 8 tires on each line, every module can be make as 2, 3, 4, 5 and 6 as one unit, which can be spliced longitudinally or horizontally; all axles can steering.


What types of loads can be transported using a modular trailer for heavy equipment?


Modular trailer is mainly used for the transportation of super heavy, large-scale, over high and special-shaped, and so on over dimension cargo (ODC cargo). Its advantages are flexibility to use, convenient loading and offloading, and the load capacity can reach more than 50000 tons under the condition of multi-vehicle mechanical assembly or free combination. Modular trailers for heavy equipment are widely used in equipment manufacturing, petroleum, chemical engineering, offshore oil, bridge construction, and other engineering fields.


What is the maximum weight that a modular trailer can carry?


A modular trailer for heavy equipment is a special vehicle, which is composed of multiple modular modules. The single line of the modular trailer can carry max 45 tons. The overall length of the modular trailer can be freely spliced according to the needs of cargo loading, and the max loading capacity can reach more than 1,000 tons.


How is a modular trailer loaded and unloaded?


Modular trailers have a unique suspension of hydraulic systems, which have a total stroke of 600mm, so it is easy to adjust the platform of the trailer and go through under the cargo. To finish the loading and offloading of cargo easily which can without involving crane help during the operation.
