Precision in Motion: LDMC's Heavy-Duty Shear Takes Shape
August 11, 2025 - Yichang, Hubei

The workshop at Hubei LIDI hums with activity as overhead cranes maneuver 80mm-thick steel plates onto the cutting bed. These massive slabs – destined to become structural components for LIDI's 1250t gate shear – are undergoing precision plasma cutting. Sparks cascade as computer-guided torches trace complex contours with 0.5mm tolerance, transforming raw material into load-bearing side frames.

Engineering at Scale
Each 6×3 meter plate requires three hours of uninterrupted cutting, with infrared sensors continuously monitoring thermal deformation. "The 1250t capacity demands absolute precision in every component," notes workshop supervisor Mr. Zhang, pointing to freshly cut sections awaiting ultrasonic testing. Nearby, forklifts transport finished parts to the pre-assembly area, where they'll undergo surface grinding.

Next Steps
With all major components expected to complete machining by the end of October, the project remains on schedule for November delivery. The final assembly will integrate LDMC's proprietary hydraulic system, capable of generating 12,500 kN cutting force – equivalent to lifting 1,250 metric tons. Production updates will continue as the shear progresses through quality validation phases.
