A modular trailer is a collection of customised trucks designed to transport massive, difficult-to-disassemble items. The trailer is also used to deliver things that are too long to fit on a truck. Power plants, the chemical industry, the iron and steel industry, and the construction sector are all key users of modular trailers. One of the safest methods to move large and over-dimensional things on the road is using a modular trailer. The modular trailer's gross loaded weight is set depending on the maximum load per axle. The unladen weight of them should be as little as possible in order to have a larger payload capacity. Because the frame bears the majority of the load (unladen), weight minimization may be done to boost the trailer's payload capacity. The modular trailers are available in two-axle, three-axle, four-axle, five-axle, six-axle, and eight-axle variants. A maximum load of 40 tonnes per axle is possible. The modular trailer has a higher carrying capacity since it has more axle lines.

Components of a modular trailer
&#; Frame
The frame's primary girder features a box-type carrying beam construction. To ensure stability and dependability, the girder is made of high-performance welding steel. The frame's surface needs to be cleaned. Sandblasting should be applied to the main structure's surface. The thickness of the surface painting should meet national regulations.
&#; Wheel boogie
The hydraulic wheel bogie, which comprises the bogie frame, hydraulic cylinder, axle, tyre, and rocker arm, is used in the modular unit. It can carry a lot of weight. The axle swings to adjust for unevenness in the transverse direction of the road. The hydraulic lifting system adjusts the modular supporting system if the road is uneven in the driving direction.
&#; Break
A pressurised air brake mechanism is included in the modular unit. Double brake chambers, single brake chambers, relay valves, brake drums, and reservoirs are all part of the system. The braking system is made up of two brake lines, one for the service brake and the other for the parking brake.
&#; Steering
The steering central panel, steering orifice plate, steering cylinders, and steering rods make up the steering mechanism. The steering orifice plate and the bogie frame are soldered together. The plate features a certain number of assembly holes for installing steering rods. The placements of the steering rods on the steering orifice plate may be adjusted to suit the modular unit's various combination modes.
&#; Suspensions
A hydraulic modular trailer's separate swing axles are made up of hydraulic suspension that may be coupled to various support circuits. The suspension is connected to multiple circuits to guarantee that the axles are loaded equally. Even while driving over difficult terrain, proper lengthwise and crosswise levelling is ensured when the axles are loaded equally. Extreme cross falls are likewise controlled by equal loads.
Advantages of modular trailer
&#; Modular trailers can handle tasks that traditional trailers can't. A modular trailer should, in theory, have a variety of gear built into it.
&#; It might have a bed attached to a frame of a specific width and length. A transportation conveyance that reaches the ground surface and another that does the same but is attached to the opposite sides of the mainframe are among the other devices.
&#; A towing arm with a bed element freely connected to a tow element may be included in the modular trailers' equipment.
&#; The tow element might be coupled to a coupler on the trailer that is configured to securely attach to ball hitches or any other tow hitch.
Here is all the coverage on the modular trailer that one needs to go through before either purchasing or hiring a trailer for themselves.

(10). Self propelled traction combination: It combine the power unit module (PPU) device and self-propelled unit module to be one ,which used as a power plant. Then combined with modular trailer to achieve self-propelled modular trailer. This power plant have hydraulic drive walk, hydraulic drive turning, hydraulic lifting suspension system and air brake function. But only used under the special transportation conditions( lowest speed to transport heavy cargo, under 5km/h), it can completely replace the traditional tractor.
(11). Hydraulic power unit and hydraulic control box is the hydraulic power supply and hydraulic pressure control equipment of hydraulic modular trailer. Manual operation can realize trailer steering of the vehicle and the adjustment and maintenance.
(12). Concave plate girder and flat beam are the accessory equipments which designed for oversize and overweight cargo.
(13_. 200 tons of rotary table is used on hydraulic modular trailer, need paired use. To help transport maximum weight of 200 tons.

Product main technical characteristics
&#;Modular trailers can be separated and also combined. It is easy to operate conveniently.
&#;Transverse or longitudinal combination between modular trailers. In longitudinal combination,it use hydraulic connection pin, hydraulic pressure to force,it is very easy to operate.
&#;The module trailer can be combined to three modes of combined hydraulic modular trailer through accessory equipments and combination accessories.Full trailer mode, Semi trailer mode, Self-propelled mode.
&#;Combined hydraulic modular trailer is consisted of two or more independent units modular trailer. It can satisfy various requirements of transportation.
&#;Good safety, high reliability
&#;Using the high performance quick change connector plug to connect hydraulic and gas circuit. Good sealing, convenient operation.
&#;Electrical interface use international famous brand engineering heavy plug connector,reliable connect, hydraulic modular combination is fast and easy to operate.
&#;The steering system of our hydraulic modular trailer install independent overflow valve to ensure the system pressure security. And also ensure the security of steering cylinder and steering mechanism.
&#;Braking system use double line pressure brake arrangement, have service braking and parking braking. On both sides of the trailer install manual control valve, in emergency situation, operate the valve, can achieve air brake,to improve the ability of emergency treatment.
&#;Box structure beam design, good frame carrying ability.
&#;Frame girder for box beam structure,material with high performance welding steel plate HG785,good strength and bearing ability.
&#;Lifting function.
&#;The hydraulic modular suspension system uses hydraulic suspension,to achieve the elevator function, elevator amplitude + 300 mm.Mainly combined by rotating frame, swinging arm, hydrocylinder and type. Good bearing ability.
&#;Main advantages as follows:
&#;Can achieve three points support and four points support.Three hydraulic support has no positioning,when trailer run under the poor road conditions, three points support can effectively protect frame structures are not destroyed. Four points hydraulic support has positioning support mode, when the trailer run under the good road conditions,use four points hydraulic support to improve cargo loading stability, it is good for cargo security.
&#;Can adjust frame horizontal position when run slope and ramp road.
&#;Frame and platform can lift to achieve some loading and unloading.
&#;If the trailer is under heavy load, the Tyre should be changed that through mat sleeper make girder fall to the ground.
&#;Can lift wheel and axle independently, for easy to maintain and replace tires.
&#;Multi-mode steering function
&#;Steering system installs steering,cylinder,turning center plate,steering track rod and steering orifice plate. Steering orifice plate and suspension are welded one, it installed a certain number of steering rod mounting hole, by different combinations of axis, to transform steering track rod combination mode,can achieve combination need the minimum turning radius,the largest wheel steering Angle is 55 °. Steering hydraulic system equipped with hydraulic valve components,change the hydraulic valve assembly open combination state,can realize &#;steering, normal car steering, oblique line three steering mode.
&#;Power unit is small, do not occupy cargo loading platform space
&#;Power unit use the German air cooling engine,small size, is a set of independent system,hydraulic tank built-in frame, can make the power unit hooking in front of vehicle or in behind of vehicle.Do not occupy cargo loading platform space(So it can achieve 40 axle -lines combination)
&#;Hydraulic control operation and power unit can be together, also can be independent hook on the trailer, it can satisfy various requirements.
