CPTC: Your Partner in Crane Safety and Efficiency

For construction professionals, choosing a supplier who understands the complexities of mast section manufacturing is essential for long-term safety and operational efficiency. At CPTC, we are committed to delivering mast sections that meet — and often exceed — the performance standards of major OEM models through meticulous engineering and quality control.

Precision Manufacturing:
We specialize in producing fully compatible replacement mast sections for leading brands such as Potain, ensuring our components precisely match the critical dimensions and connection points of the original parts. Our manufacturing process employs advanced jigs and fixtures to maintain strict tolerances, particularly in pinhole alignment — a key factor for both safety and ease of assembly.

Superior Material Control:
We exclusively source high-grade Q345B structural steel, with factory certification verification for every batch. This commitment guarantees the yield strength and toughness required for high-stress crane applications, especially under demanding weather conditions.

Optimized Design and Testing:
Our engineering team focuses on optimizing the truss geometry and the thickness of the main chords and diagonals (braces). Every section undergoes rigorous non-destructive testing (NDT), especially for load-bearing welds, to ensure structural integrity and extended service life.

Contact our engineering team today to ensure your tower crane’s backbone structure is strong enough to handle the challenges of tomorrow.
