Hydraulic cylinder

I. Basic Product Information
Product Name: Side Discharge Hydraulic Cylinder for Semi-Trailers
Material: High-strength steel
Specifications: 4TG120×750
Application Scope: Dump trucks, side-unloading semi-trailers, baling presses, mining equipment, industrial equipment, etc.
II. Main Features and Advantages
1. Sturdy main structure, long service life
Manufactured from integrated machined steel. It features impact resistance and fatigue resistance, free of deformation under long-term heavy loads, suitable for high-intensity working conditions.
2. Automatic welding technology to prevent leakage
Oil ports are welded by automatic equipment. Weld seams are uniform, free of pores and slag inclusions. It maintains stable tightness during long-term high-pressure operation and frequent lifting, with zero leakage risk.
Upgraded sealing system ensures smooth and reliable operation
The full set of sealing rings and dust seals resists uneven loads, impacts and dust intrusion. It prevents oil leakage and component wear, delivers smooth lifting without jerks or jamming, and reduces failure risks.
4.High-precision machining, smooth cylinder movement
Key components are machined by CNC equipment, delivering high coaxiality and ultra-small clearances between cylinder stages. The structure resists bending under lateral loads, enabling smooth lifting and lowering with low friction resistance.
Multi-stage structure with wide compatibility
3–6 stage models are available. Long working stroke with compact mounting space. Suitable for side and rear tipping of semi-trailers and dump trucks, featuring high efficiency and easy installation.
5. Sufficient structural margin for safe operation
It is equipped with sufficient load capacity and structural safety margin, operates stably under long-term high pressure, and cuts down operational risks.
