Product Introduction
The telescopic pull-out type low-bed semi-trailer is a low-bed semi-trailer whose platform can adjust length through telescoping and pulling, flexibly adapting to the loading, unloading, and transportation of large cargo of different sizes (such as engineering machinery and ultra-long steel).
Product Details
This vehicle is specially designed for transporting ultra-long and overweight cargo. It adopts hydraulically driven telescoping, with multi-section telescopic cylinders combined with pneumatic bolt locks for graded positioning, and a sliding ball support structure to reduce telescoping wear. It is equipped with customized high-end dedicated axles, with optional air suspension to achieve 400mm height compensation, and WABCO dual-circuit air brake + ABS to ensure safety.
The frame is formed by high-strength steel via automatic submerged arc welding, with shot blasting anti-corrosion treatment. It is equipped with hydraulic ramps and container locks, adapting to heavy-load transportation in multiple global scenarios.

Smooth telescoping; sealed structure prevents sand and mud intrusion. |
|
Locking Device |
Pneumatic bolt locks with locking indicators on both sides, for graded positioning |
Ensures platform stability after extension, avoids displacement during transportation, and improves safety. |
|
Main Beam |
Q345B/Q550D/T700 high-strength steel, 450-550mm high; upper and lower plate thickness: 12-35mm; middle plate: 10-20mm |
Automatic submerged arc welding process, reinforced crossbeam design; withstands 20 tons/4m point load without deformation. |
|
Platform Floor |
4-5mm checkered steel plate or 30mm hardwood |
Checkered plate is anti-slip and wear-resistant; hardwood floor is suitable for precision equipment to reduce transportation wear. |
|
Side Beam |

Each lug has a tensile strength of 5-10 tons, meeting the fixing needs of large cargo. |
Product Advantages
Flexible telescoping with strong adaptability: The platform can extend to over 22 meters via hydraulic drive, matching ultra-long cargo of different lengths as needed (such as wind turbine towers and long rails).
Balancing heavy load and durability: The frame is made of high-strength steel, formed by automatic submerged arc welding. The overall configuration can reach a maximum load of 120 tons, with a stable structure that is not easily deformed. It is equipped with BPW/FUWA brand axles, with optional air suspension.
Excellent safety and compliance: Equipped with WABCO dual-circuit air brake system + ABS anti-lock device, with rapid braking response to reduce the risk of heavy-load driving. After shot blasting derusting treatment, it has passed international certifications such as ECE and GCC, smoothly adapting to market access requirements in multiple global regions.
Application Scenarios
Mainly used in overseas infrastructure, wind power, and mining. It can transport ultra-long and overweight equipment such as wind turbine towers and excavators. It is a core equipment for multimodal transport and heavy cargo logistics.
