SY375 Mining Bucket — The Ultimate Earth-Moving Tool for Extreme Conditions

Product Overview
The SY375 Mining Bucket is a heavy-duty attachment engineered specifically for 37-40 ton class large mining excavators (compatible with mainstream models like theSY375H, E 390,  PC400, etc.). Built with a pioneering design philosophy and premium materials, it is purpose-built for the most severe operating environments such as ore extraction and heavy rock excavation. It is designed to deliver exceptional durability, maximum uptime, and superior digging efficiency, making it the ultimate equipment choice for mining customers aiming to reduce costs and boost productivity.

Core Design Philosophy: Built to Endure
We understand that mining operations push equipment to its limits. The SY375 Bucket moves beyond standard designs, incorporating principles of reinforcement, wear resistance, and high efficiency into every detail, ensuring it remains robust through relentless cycles of impact, abrasion, and stress.

1. Key Features & Benefits

A. Extreme Wear Resistance, Extended Lifespan

• Material Innovation: Critical stress areas (base plate, side cutters, tooth adapters) are constructed from imported Hardox 500 wear-resistant steel, offering 4-5 times the abrasion resistance of standard steel with excellent impact toughness.

• Comprehensive Protection:

  • Reinforced Floor: A thickened base plate paired with a bolt-on main wear strip creates a double-layer defense.

  • Dual Side Protection: Equipped with side wear plates and integrated box-type side guards to effectively resist material scour and protect the bucket's core structure.

  • Robust Adapters: Forged alloy steel tooth adapters compatible with major brand teeth (e.g., CAT, ESI). They ensure secure fitment and allow for easy replacement when worn.

B. Optimized Structure for Maximum Force

• Engineered Profile: The bucket profile is optimized using Computational Fluid Dynamics (CFD) simulation. Its smooth curvature reduces loading resistance, increases fill factor, and improves payload per cycle.

• Box-Section Reinforcement: The main body utilizes a multi-chamber box beam design, enhancing overall torsional and bending strength while optimizing weight, enabling it to handle off-center loads with ease.

• Stress-Dispersing Design: All reinforcement ribs and weld layouts are engineered using Finite Element Analysis (FEA) to eliminate stress concentration points, preventing cracks at their source.

C. Efficient Material Release

• Strategic Grid Pattern: Features a calculated heavy-duty ridged grid on the floor for rapid separation of fines from rock when handling fragmented material, significantly improving truck loading quality and efficiency.

• Optional Configuration: A solid plate floor version is available for fine-grained or clay material applications.

D. Easy Maintenance, Lower Total Cost of Ownership (TCO)

• Modular Wear Parts: All wear plates, side cutters, and main edges are bolt-on, eliminating the need for in-field welding and allowing for fast replacement directly on the machine, minimizing downtime.

• Integrated Lifting Points: Designed with safety lifting lugs for easy transportation, installation, and handling.

• Extended Service Life: Superior durability translates to fewer replacement intervals and repair costs, significantly reducing long-term Total Cost of Ownership.

2. Technical Specifications (Example)

• Compatible Machines: 37-40 Ton Class Large Excavators
