Ships are part of the heaviest load transported on the road. After 5 months of discussions and exchanges, we recommend the most suitable multi axle trailer for customers. Professional engineers design drawings according to the actual situation of customers to provide customers with references. The final customer chose TITAN to cooperate.
The multi axle trailer has enough capacity and space to accommodate such heavy and bulky cargo.
The hydraulic system consists of five major parts with different specifications and functions. The parts include the hydraulic brake system, hydraulic cooling system, hydraulic lifting system, hydrostatic drive system, and hydraulic steering system.
1. The hydrostatic drive system
The system refers to a closed-loop hydraulic system with a variable drive pump. The control type of the variable pump is an electric proportional control.
The drive system use pressurizes liquid to power the 200 ton multi axle trailer. The term hydrostatic, in this case, refers to the transfer of energy or power from flow and pressure. The term does not include the kinetic energy of the liquid flow.
2. The hydraulic steering system
This system is an open-loop system with an open-loop variable pump. The pump has two major functions that include loading sensing and controlling pressure-cutting-off flow.
It can adjust the output flow of the variable pump based on the needs of the load. Adjusting the flow also saves energy. The pressure-cutting-off flow control function enables the operator to restrict the variable pump’s maximum output pressure.
The main reason for restricting the pressure is to protect the hydraulic system from potential damages.
3. The hydraulic lifting system
The hydraulic lifting and steering system share the same open-loop variable pump. The hydraulic oil from the variable pump is shared equally between the lifting and steering cylinders.
Consequently, the platform of the semi multi axle trailer for sale lifts evenly and remains horizontal when lifting.

4. The hydraulic cooling system
The cooling system consists of two gear motors that drive fans that cool the composite radiator. One gear pump is used to supply the hydraulic oil under great pressure to the two gear motors.
5. The hydraulic brake system
The brake system in a modular transporter and its parking brake work when the hydraulic brake cylinder is pushed and the brake drum is released.
The brake cylinder has springs that keep the transporter in the parking brake state when the cylinder has no pressure oil. The braking system has a manual pump, which is used to release the parking brake when there is no power in the vehicle.
The hydraulic suspensions are divided into different wheel bogies. The bogies include wheel bogies with brake, wheel bogies with drive, and wheel bogies without brake. The hydraulic suspensions consist of a hydraulic suspension cylinder, bogie frame, axle with drive, axle with brake or without brake, rocker arm, and tire.
The gear shaft sleeves are usually welded onto the bogie frame and a hydraulic suspension cylinder is placed between the rocker arm and bogie frame.
The motor and reducer are installed on the wheel bogies with a drive to provide the driving force for the modular transporter. The wheel bogies with brake are usually installed together with the axle with brake that has a brake cylinder on it. The cylinder has the parking and service brake for the vehicle.
The three different types of wheel bogies used in the transporter have a mechanical stopper that limits the maximum position. The stopper uses the minimum stroke of the hydraulic suspension cylinder in order to control the lowest position.
