2. What are hydraulic modular trailers and why are they called super-trucks?Hydraulic modular trailers are giant trucks that can carry huge things like buildings and bridges. They are called super-trucks because they can lift and move loads that are thousands of tons, far heavier than normal trucks.
3. How do hydraulic modular trailers move such big loads?They use a network of hydraulic cylinders, pumps, and fluid lines to control the trailer’s height and steering. This lets the trailer bend, lift, and turn even when carrying very heavy cargo.
