Heavy Duty Multi Plate Pintle Chain

Product Description

Our Multi-Plate Pin Chains are designed for heavy-duty lifting and conveying applications where high tensile strength and excellent fatigue resistance are required. Featuring multiple stacked plates connected by high-strength pins, these chains provide superior load-carrying capacity and reliable performance under demanding working conditions.

Key Features & Benefits

1.Multi-Plate Construction:

• Features multiple, parallel steel side plates on each link. This dramatically increases the chain's cross-sectional area at the most critical stress points, distributing the load more evenly and providing vastly higher tensile strength and fatigue resistance compared to single-plate designs.

2.Heavy-Duty Solid Pin & Bushing System:

• Utilizes large-diameter, precision-ground solid pins or case-hardened pins that rotate within specially designed steel bushings. This configuration provides an extended bearing surface, significantly reducing bearing pressure and resulting in exceptional wear life and minimal elongation under sustained heavy loads.

3.Optimized for High Torque / Low Speed:

• The design philosophy centers on transmitting massive torque at low to moderate speeds. Its inherent strength makes it ideal for applications where shock loads, high static loads, or abrasive environments are primary concerns, rather than high rotational velocity.

4.Enhanced Rigidity & Stability:

• The multi-plate structure provides exceptional lateral and torsional rigidity. This ensures stable engagement with large sprockets, minimizes whip and vibration, and maintains precise alignment in long-center-distance drives.

5.Customizable Configurations:

• Available in various plate widths, pin diameters, and materials (e.g., carbon steel, alloy steel, stainless steel). Can be supplied with standard or hardened components, and with attachments welded or bolted to the side plates for specific conveying duties.

Scope of Application

• Marine & Offshore: Main propulsion drives, winch drives, and capstans on workboats and large vessels.
• Heavy Industrial: Drives for large ball mills, kilns, crushers, and drag conveyors in mining, cement, and aggregate industries.
• Material Handling: Bucket elevators, heavy-duty slat conveyors, and scraper conveyors handling bulk materials like ore, rock, and gravel.
• Specialized Machinery: Drives for large presses, extrusion machines, and forestry equipment.

Close cooperation with factories

We maintain deep, long-term partnerships with the factory around 20 years. The factory has strong mechanical and automated production capabilities which ensure stable quality and performance of the products.

Quality control

The factory's rigorous quality control process includes material spectroscopy analysis, in-process inspections, and final checks with Magnetic Particle Testing (MPT) to ensure every bucket is free from defects and meets our high standards. The details control process as below,

1. Incoming raw materials undergo random sampling and analysis using a microscope to ensure the chemical composition meets production requirements.

2. During the production process, QC staff conduct timely sampling to ensure products are defect-free and handle any abnormal quality issues that may arise.

3. The final step involves using a magnetic particle flaw detector on metal parts to detect hidden cracks or defects.

4. All finished metal parts are proportionally sampled and sent to the laboratory for mechanical performance tests, size measurement, and 100% manual surface quality inspection.
