Aodovo Machinery manufactures high-quality tensioning devices customized for various rotary drilling rigs, compatible with mainstream models of Bauer, CAT chassis, Soilmec, Jintai, Sunward, SANY, CSR, Yutong and other brands. As a key component of the rotary drilling rig's track system, the tensioning device automatically adjusts track tension through the cooperation of hydraulic cylinder and spring components, preventing track chain slack, deviation and derailment, and ensuring smooth track operation. Made of high-strength alloy steel and processed with precision machining and sealing treatment, our products can effectively resist mud and dust intrusion under high-load and high-impact pile foundation construction conditions, extend the service life of the cylinder and spring, and ensure stable and reliable equipment walking.

Product Features
1
High-strength Material: The cylinder barrel, piston rod and spring components are made of high-quality alloy steel and quenched and tempered, featuring high strength and good toughness, which can effectively resist construction site impact and wear, and are not easily deformed or broken under long-term use.
2
Precision Sealed Structure: Adopts multi-channel imported oil seals and dust rings to effectively prevent mud and dust from entering the cylinder, avoiding hydraulic oil leakage, extending cylinder service life and adapting to harsh working conditions.
3
OEM-level Precision Compatibility: Produced in strict accordance with original size standards, the mounting holes, cylinder stroke and spring elasticity are completely matched with the equipment chassis. The automatic tensioning effect is stable, no additional modification is required, and they can be directly replaced and installed.
4
Optimized Structural Design: Adopts a composite structure of hydraulic cylinder + spring with adjustable tension, which can automatically compensate for track chain wear and slack, reduce track chain impact load, minimize track chain and undercarriage parts wear, and extend the service life of the entire walking system.
