Heavy Duty High Tensile Plate Link Chain

Product Description

Our plate chains (leaf chains) are specially designed for lifting, hoisting, and heavy-duty material handling applications. With high tensile strength, excellent fatigue resistance, and reliable performance, they are widely used in forklifts, stackers, lifting equipment, and industrial machinery.

Key Features & Benefits

1. High Strength & Durability

• Manufactured from premium alloy steel and processed with advanced heat treatment to ensure superior tensile strength and long service life.

2. Compact Structure

• Composed of interlaced plates and pins without rollers, providing a compact design ideal for lifting systems with limited space.

3. Excellent Fatigue Resistance

• Engineered to withstand repeated loading cycles, ensuring stable performance in harsh operating environments.

4. Smooth & Reliable Operation

• Precision-machined plates and pins provide smooth operation and minimal elongation under load.

5. Corrosion Protection

• Surface treated with anti-rust coating for extended durability.

Scope of Application

• The Leaf Chain is essential for any equipment requiring stable, high-tension vertical or horizontal movement:
• Forklift Trucks (Lift Trucks): The primary application, driving the forks up and down on the mast.
• Lifting Equipment: Hydraulic lifts, hoists, and aerial work platforms.
• Material Handling: Conveyors and machinery requiring heavy load balancing or counterweights.

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 controll 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.
