In heavy transport, the turntable plays a key role in steering performance and overall control, especially when moving oversized loads through tight roads and complex job sites. At first glance, a mechanical turntable and a hydraulic turntable may look similar, but their working principles and real-world performance are very different. A mechanical turntable relies on fixed mechanical linkages and passive rotation. Its structure is simple and proven, making it suitable for standard transport tasks and stable road conditions. However, when facing sharp turns, uneven ground, or frequent steering adjustments, its response is limited by mechanical geometry and friction. Operators often need ...

The anti-slip surface treatment process is a small detail that plays a big role in the real operation of Supro hydraulic modular trailers. In heavy transport, safety does not depend on one single component. It is built through many practical design choices, and surface treatment is one of them. During loading, unloading, and on-site assembly, operators often work on the trailer deck in dusty, wet, or oily environments. A smooth steel surface can easily become slippery, increasing the risk of accidents and reducing work efficiency. For this reason, Supro applies a dedicated anti-slip surface treatment designed specifically for hydraulic modular trailers. The process starts with proper sur...

Producing a split-version drop deck bed is far more complex than it appears. Unlike a one-piece structure, a split design must maintain strength, stability, and accuracy while allowing flexibility for different transport tasks. Every detail matters, from the structural layout to the final on-site assembly. One major challenge is load sharing. When the deck is divided into sections, each part must carry its share of the load evenly. During heavy transport, road conditions change constantly, and uneven stress can easily occur. This means the beam structure, connection points, and reinforcements must be carefully designed and verified through real load calculations, not assumptions. Another...

Producing a split-version drop deck bed is not just about cutting a deck into sections. It is a process that tests structural design, manufacturing accuracy, and real transport experience. Compared with a one-piece drop deck bed, the split version must handle more complex load paths while keeping the overall structure stable and reliable during heavy transport. One of the biggest challenges is load distribution. When the deck is split, each section must share the load evenly under different road conditions. This requires precise structural calculations and careful matching of beams, joints, and connection points. A small error in design can lead to uneven stress, which affects safety and long-...

In heavy transport projects, many customers ask whether 3-file and 4-file hydraulic modular trailers can be used together with a hydraulic gooseneck. The short answer is yes, but the configuration and application conditions must be clearly understood. A hydraulic gooseneck is mainly used to connect the modular trailer to the tractor while providing lifting and height adjustment during loading and unloading. For 3-file and 4-file modular trailers, compatibility depends on factors such as axle load, total combination length, steering mode, and transport terrain. When properly designed, the hydraulic gooseneck allows smooth load transfer and stable operation, especially for oversized and heavy...

A customer from Korea spent a full day at the Supro Trailer workshop testing the STN-V3 multi-axle hydraulic modular trailer under real working conditions. Instead of a brief inspection, the customer chose to operate the trailer personally, focusing on structure, hydraulic response, steering behavior, and overall handling. Throughout the day, the STN-V3 was tested in different configurations to evaluate stability and flexibility. The customer carefully observed how the hydraulic suspension adapted to load changes and uneven ground, checking whether axle loads remained balanced during lifting, lowering, and steering movements. Special attention was given to connection points, pin a...

This guide explains how to use the remote control to operate the steering system of a windmill blade extendable trailer in a clear and practical way. The goal is to help operators achieve precise control during transport, especially when handling long blades on narrow roads, curves, and site entrances. Before operation, make sure the hydraulic system is fully pressurized and the remote control is properly connected. Check that all steering axles respond correctly in neutral mode. Once confirmed, switch the system to steering control mode using the remote. This allows the operator to adjust axle angles in real time, matching the trailer movement to road conditions. During low-speed ...
