Rigorous Quality Control
Every DADH brake undergoes comprehensive factory acceptance testing (FAT) to ensure reliable performance in lifting and slewing mechanisms:
Pressure & Leakage Testing – 100% of units are subjected to static and dynamic hydraulic holding tests at 1.5 times maximum operating pressure to verify zero fluid leakage.
Braking Torque Validation – Dynamic tests ensure stable clamping force across operating temperatures from -20°C to +50°C.
Material Traceability – Critical load-bearing components and premium imported seals are fully traceable; material test reports (MTRs) available upon request.
Certified Quality – All DADH brakes are manufactured under ISO 9001 quality management standards and comply with relevant CE and industry safety certifications, ensuring international compliance and reliability for OEM and industrial applications.
