- Long-term sealing performance: High-quality seals and multi-channel combined seals (O-rings + dust rings) are used to prevent hydraulic oil leakage and contaminant intrusion. Acid and alkali resistant seals can be selected for special working conditions.
- Widely applicable: Suitable for various models of crawler excavators, such as PC60-7, PC120, PC200-6, PC200-7, PC300-6, PC300-7, etc.
- Working pressure: The rated working pressure is usually 10MPa, and the maximum allowable pressure can reach 16MPa.
- Working temperature: The designed temperature resistance range is -25℃ to +120℃.
- Spring parameters: Taking PC120 tightening cylinder as an example, the spring free height is 507mm, the installation height is 390mm, and the load weight is 78500N.m.
- Comprehensive after-sales service: 2-year warranty on core components, video technical support, online support, spare parts, and on-site maintenance services are available.
- Customizable and reliable: Mechanical test reports and video factory inspections ensure the quality and reliability of the products to meet specific requirements.
