Key Functions 
Motion Conversion: Converts rotary motion to linear reciprocating motion (and vice versa), powering core truck systems like engines, lift pumps and air compressors for stable operation.
Performance Optimization: Fine-tunes drive belt/chain tension and adjusts valve timing to boost engine power output and reduce fuel consumption.
Vibration Reduction & Balance: Precision dynamic balancing design offsets inertial vibration of engines and transmission systems, minimizing component wear and lowering operation noise.
Special Equipment Drive: Drives dedicated truck attachments, such as dump truck lifting mechanisms and refrigerated truck compressors, ensuring accurate action control under varying loads.

Core Features
Heavy-Duty Material & Craftsmanship:Made of high-strength alloy steel, quenched and tempered for superior impact resistance and wear resistance, ideal for harsh road conditions.
High-Precision Manufacturing: Strictly controlled eccentricity, chrome-plated and precision-ground shaft necks, paired with high-pressure lubrication systems to reduce friction and extend service life.
Reliable Installation & Maintenance: Keyway/flange positioning prevents slippage during operation; preset inspection benchmarks allow easy wear measurement, cutting down maintenance time and costs.
Versatile Compatibility: Redundant structural design adapts to both light-load and heavy-load scenarios, suitable for stock replacement or modification of various trucks, dumpers and special-purpose vehicles.
