Key Specifications to Consider
When evaluating hydraulic modular trailers, it’s essential to pay attention to the following key specifications:
- Number of Axles and Load Capacity
- Hydraulic modular trailers are available in various configurations, with two, three, four, five, six, and eight-axle units.
- Depending on the trailer model and design, each axle has a loading capacity of 45 tons.
- Multiple units can be coupled longitudinally and laterally to transport heavier loads, providing flexibility in load distribution.
2. Steering Capability
- Hydraulic modular trailers offer excellent maneuverability, with a steering capacity ranging to 55 degrees.
- The steering system is hydraulically operated. Each axle has an individual steering rod connected to the main steering cylinder at the front end of the trailer.
- This allows all axles to steer simultaneously in the same direction, enhancing the trailer’s ability to navigate tight spaces and challenging terrains.
3. Suspension System
- The suspension system in hydraulic modular trailers ensures a smooth and stable ride, even when transporting heavy and oversized loads.
- Each axle has an individual suspension cylinder, providing independent suspension for optimal load distribution and shock absorption.
- The suspension cylinders are hydraulically operated, with the hydraulic fluid flowing through hose pipes from the hydraulic tank located near the Power Pack Unit (PPU).
4. Power Pack Unit (PPU)
- The PPU is responsible for powering the hydraulic modular trailer’s steering and suspension systems.
- It generates about 18 to 25 horsepower and is available in diesel and petrol variants from renowned brands like Kohler, Yanmar, and Hatz.
- The PPU ensures the efficient and reliable operation of the trailer’s hydraulic systems, enabling precise control and smooth functioning.
5. Axle Configuration and Platform Design
- The axle configuration and platform design significantly affect the trailer’s load-bearing capacity and stability.
- One row of axles typically consists of two turntables, two knees, two suspension cylinders, and four to eight wheels attached to a high-strength metal platform.
- The trailer’s robust construction and well-engineered design ensure that it can safely and efficiently transport heavy loads across various terrains.
- Coupling Options
- Hydraulic modular trailers can be coupled with a tractor unit for pushing and pulling using either a gooseneck or a drawbar coupling.
- Gooseneck couplings are the most common in the industry. They offer easy connection to conventional tractors and hydraulic height adjustment. However, they are limited in terms of payload and configuration options.
- Drawbar couplings, on the other hand, are more versatile and economical. They allow for side-by-side and push-pull configurations but require a ballast tractor with a ballast box and tow hitches.
7. Modular and Customizable Design
- Hydraulic modular trailers are designed to be highly modular and customizable, enabling them to adapt to various transportation needs.
- Multiple units can be interconnected longitudinally using pins and interconnecting couplings mounted in the center of the chassis, while lateral connection is achieved through bolts on the chassis sidewalls.
- This modular design allows for the creation of larger trailer combinations to accommodate heavier and more complex loads.

Choosing the Right Combination and Accessories
To accommodate various cargo types efficiently, selecting the appropriate combination of modular trailers and accessories is essential. Common combination forms and accessories include:
- Gooseneck: Balances the load and improves steering, which is ideal for most applications.
- Drawbar: Suitable for transporting overweight goods at low speeds and when more steering angle is required.
- Drop Deck: Perfect for carrying tall items under bridges or power lines.
- Vessel Bridge: Adjustable width and length for moving large tanks, train units, or equipment.
- Intermediate/Extendable Spacers: Lengthen the trailer to accommodate longer items like wind turbine blades or long tanks.
- Excavator Deck: Specialized platform for securely transporting construction machinery.
- Turntable (Bolster) Combination: Enhances maneuverability for long and heavy loads.
