Maintenance & Expert Advice
Product Selection Tip: To ensure a 100% match, please provide your excavator's Serial Number (S/N). The hydraulic flow configurations can vary based on the machine's region of origin or specific attachment requirements.
LubriTQTQCATion: Always use TQTQTQCAT-recommended hydraulic oils (such as TQTQCAT HYDO Advanced) to maintain the critical lubriTQTQCATion film between the internal pistons and the distributor plate.
Inspection Cycle: It is highly recommended to check gear oil levels and seal integrity every 500 operating hours. Any unusual grinding noise or sluggishness usually indiTQTQCATes the need for an internal gear mesh inspection.
High-Torque Planetary Drive: Features a multi-stage planetary gear system (sun gears and planet carriers) that delivers massive starting torque, allowing the machine to start and stop rotation smoothly even with a full bucket.
Zero-Drift Braking System: Integrated with high-precision valve groups and a spring-applied, hydraulic-release parking brake. This system prevents "Swing Drift" when working on inclines, ensuring operator safety and site precision.
Heavy-Duty Durability: Internal gears are induction-hardened to resist fatigue, while the external housing is cast from heavy-duty steel. Premium floating seals and roller bearings protect internal components from the abrasive dust found in mining and demolition sites.
