What Makes a Reliable Casing for Telehandlers?
Telehandlers, or telescopic handlers, are powerful machines used across construction sites, agricultural fields, and industrial yards. Known for their extended reach and lifting capabilities, these machines rely on a strong and durable telescopic boom to perform heavy-duty lifting jobs safely.
At the heart of that boom? A precision-engineered steel casing — the unsung hero that supports movement, stability, and longevity.
The Challenge: Ordinary Pipes Can’t Keep Up
Standard pipes or welded structures often fail to meet the strict requirements for telehandler booms, especially when exposed to:
- Constant extension and retraction
- Heavy vertical and horizontal loads
- Outdoor environmental conditions
Problems such as weld seam fatigue, inconsistent wall thickness, or limited tensile strength can lead to breakdowns and expensive downtime.
Our Solution: Integrated Casing Pipe for Telescopic Booms
At YIGE, we manufacture custom seamless and special-shaped steel pipes specifically designed for telescopic structures like those in telehandlers.
One of our featured products is a Q550D high-strength rectangular tube, engineered with precision dimensions and one-piece forming, replacing traditional two-plate welded boom designs.
Why Our Casing Pipe Works Better for Telehandlers
| Feature | Benefit |
|---|---|
| One-piece forming (no welding seam) | Increased structural integrity and resistance to fatigue |
| High-strength steel (Q500D) | Withstands dynamic loads with thinner wall, reducing total equipment weight |
| Custom mold capability | Enables precise fit for your boom’s sliding and extension mechanism |
| In-house tooling and supply chain | Faster lead time and stable quality control |
| Optimized cross-section | Minimizes wear and improves smooth extension/retraction cycles |
Application Example
This particular steel casing was developed for a telescopic handler used in construction lifting tasks. Its custom hollow profile allows smooth nesting inside the boom sections while maintaining rigidity and safety.
Instead of relying on a welded assembly, we integrated the entire shape into a single steel pipe — reducing:
- Welding defects
- Structural weak points
- Post-processing workload
- Maintenance cost in the long term
Your Design, Our Pipe
We understand that no two telescopic arms are exactly the same. That’s why we offer:
- Tailored cross-sections
- Material flexibility (Q460, Q500D, or higher)
- Support for drawings, prototyping, and tooling
From drawings to production — we are your partner for high-performance steel pipe solutions.
