Forging Bucket Teeth Bucket Teeth for Excavator 6Y3552A Replacement Parts

Highlights of the 17th China (Beijing) International Construction Machinery Exhibition (BICES 2025) ‌ - collaborative innovation throughout the entire industrial chain: Accelerated domestic substitution ‌

1. Breakthrough in core component technology ‌

Hengli Hydraulics ‌ : showcased the world 's largest displacement electronically controlled hydraulic pump (500ml/r), with a pressure tolerance of up to 50MPa, breaking the monopoly of Bosch Rexroth and being suitable for 400-ton class excavators.

Weichai power ‌ : released a hydrogen fuel cell (120kW) specifically for construction machinery, with no degradation during cold start at -30℃ and a lifespan exceeding 20,000 hours.

Kawasaki precision ‌ : showcasing precision electro-hydraulic proportional valves, with a response time of less than 5ms and an accuracy error of ±0.1%.

2. Integrated innovation by whole machine manufacturers ‌

Zoomlion ‌ : 10 new "green manufacturing" products, including a 62-meter hybrid pump truck (with a 45% reduction in fuel consumption) and a pure electric off-road crane (ZTC1000BEV).

CRRC Heavy Industry ‌ : An overall solution for intelligent tunnel construction, integrating tunnel boring machines (with a diameter of 12m), intelligent lining trolleys, and unmanned muck removal systems, has increased construction efficiency by three times.

Large-scale milestone ‌ : Sany SY2600E hydraulic excavator (with a self-weight of 400 tons) demonstrates heavy-load mining operations on-site, with a bucket capacity of 22 cubic meters.
