Built to Last: Our Cold-Riveted High-Strength Steel 4-Longitudinal Beam Frame Structure
مشاركة
At Shenbai Special Trucks, strength is built in — not bolted on. Here's a closer look at one of the key engineering features that sets our crane trucks apart: the 4-Longitudinal Beam Frame.
🔩 Cold-Riveted Construction
Our frames use a cold-riveting process — no heat, no warping, no weakened joints. This technique locks each connection with precision, maintaining material integrity and delivering consistent strength across the entire frame.
💪 High-Strength Steel C-Section Crossbeams — 140×80mm
The crossbeams are formed from high-strength steel C-channel sections (140×80mm), chosen for their excellent load distribution and resistance to bending under heavy stress. Welded connection braces are added on both sides of each crossbeam, creating a rock-solid junction at every node.
🛠️ The 4-Longitudinal Beam Structure
This is what we call the 4-Longitudinal Beam (四纵梁) structure — four continuous steel longitudinal members running the length of the chassis, interconnected by the reinforced crossbeams. The result:
- Exceptional rigidity — minimal flex under load
- High load-bearing capacity — built for heavy crane and cargo operations
- Long service life — durable in demanding construction and export environments
This is the foundation every serious crane truck deserves. Contact us to learn more about our build standards and available configurations. 🚛
