Product Description
Our transport semi trailer isn't just another flat deck. It's designed for heavy machinery hauling. We use high-tensile steel for the main beam, reinforced at every stress point. The deck is low to the ground, so tall excavators and bulldozers clear bridges easily. The heavy-duty spring-loaded ramps are built to handle repeated loading and unloading, no bending, no warping.
The multi-axle setup spreads the weight evenly across all wheels. We've tested these trailers with full 80-ton loads on winding mountain roads, and they stay stable-no sway, no stress on the frame. No white-knuckle driving here.

The Ramps: Built to Last
Take a look at those spring-assisted ramps. I don't mess around with flimsy hinges or weak springs. We use heavy-duty springs, and we triple-weld the base to the frame. We've had guys run an 80-ton excavator up these ramps, back and forth, hundreds of times. They still don't bend. No bouncing, no flex, just solid.
The Frame: No Weak Spots
The frame is built with Q345B high-tensile steel, with crossmembers every 30cm. We test every weld with ultrasonic inspection. No spot welds, no rushed work. The deck is 10mm thick anti-slip plate. You don't see that on every trailer. It won't warp under a heavy machine, even on rough roads.
The Axles & Suspension
Four axles spread the weight evenly. We use BPW axles, and we align every set before they leave the factory. No uneven tire wear, no early breakdowns. The leaf springs are extra heavy-duty, built for constant vibration.
Common Issues & Quick Fixes
Even the toughest trailers need occasional attention. Here's how to handle the most common problems:
Uneven tire wear
Usually caused by misaligned axles. Have the axles checked and aligned regularly.
Stuck or slow ramps
Lack of lubrication is usually the cause. Grease the hinge points and springs regularly.
Corrosion or rust
The trailer is treated with anti-corrosion paint, but regular cleaning and touch-ups prevent rust from taking hold.
Landing gear stuck or hard to operate
Grease the moving parts to keep it working smoothly.
