1.How do you prevent the mast profiles from warping during welding?
Controlling thermal distortion is critical for masts. We utilize heavy-duty custom welding fixtures and robotic welding cells to distribute heat input evenly. Post-welding, we strictly measure track parallelism using CMM metrology.
2.Do you manufacture the special steel profiles (C/J/I shapes) yourselves?
We source specialized, hot-rolled mast profiles directly from top-tier steel mills to ensure metallurgical stability. We then perform all the precision cutting, CNC machining, robotic welding, and final assembly in-house.
3.Can you deliver a fully assembled mast ready to be bolted onto the forklift?
Yes. As a turnkey central hub, we can integrate the mast weldment with your specified lift cylinders, chains, rollers, and our own manufactured hydraulic hose assemblies, delivering a true plug-and-play module.
4. Manufacturing & Inspection Basis
Mast structural integrity is paramount to operational safety. All welding processes are executed strictly under ISO 3834 standards and overseen by IWE-certified engineers to manage heat input and prevent profile distortion. Critical dimensions, including the strict parallelism of the roller tracks, are verified using Zeiss CMM measurement technology. This ensures jam-free operation and maximum structural reliability under heavy dynamic loads.
5. How to Inquire
To receive a comprehensive manufacturing evaluation, please provide your 3D CAD assemblies (STEP/IGS) and 2D engineering drawings. Please ensure your documentation details the specific mast profiles required, load center distance, lift heights, and tolerance requirements. If you require our turnkey integration services, kindly include your hydraulic routing and BOM list. Submit your files via our Contact Us form for an expert DFM review.
