Core Features
Precise Control and Transmission: Transmits handle displacement or torque to control scraper tilt/lifting, ripper movement, etc., with a control response error ≤ ±1mm, ensuring operational accuracy.
Flexible Transmission Adaptability: Can bend around obstacles such as the chassis and pipelines, adapting to transmission between non-coaxial components, simplifying mechanical layout and reducing installation space requirements.
Buffering and Vibration Reduction: Mitigates impact loads on the actuators during operation, reducing vibration transmission to the control end, improving operating comfort and protecting control components.
Long-Distance Stable Transmission: Adapts to the long-distance operation requirements of graders, with a transmission efficiency ≥98%, no significant power/signal attenuation, ensuring continuous operational stability.
Product superiority
Original Factory Precise Fit: The inner core stroke and connector specifications are 100% compatible with GD series actuators, ensuring smooth operation without jamming or loosening after installation.
High Flexibility and Fatigue Resistance:The multi-layered alternating steel wire winding structure increases torsional and tensile strength by 40%, preventing plastic deformation after repeated bending and making it suitable for high-frequency operating conditions.
Wear and Weather Resistant: The outer tube is oil-resistant and aging-resistant (-40℃ to 80℃), and the inner core surface is lubricated, reducing the coefficient of friction by 50% and extending service life.
Low Loss and High-Efficiency Transmission: Precise control of the gap between the inner core and outer tube ensures power/signal loss ≤2% during transmission, guaranteeing accurate execution of control commands.
Convenient Maintenance: Modular connector design eliminates the need to disassemble the entire machine for replacement, shortening the replacement cycle by 50% and reducing downtime maintenance costs.
Application scenarios and installation tips
Applicable Working Conditions: Suitable for conventional and continuous operation scenarios such as highway subgrade leveling, municipal maintenance, and port site grading. Especially suitable for complex operation requirements involving high-frequency blade adjustment and heavy-duty lifting of the ripper.
Installation Points: Before installation, check that the inner core is free of bends and the outer sleeve is undamaged; fix the outer sleeve according to the original factory routing, avoiding sharp bends (bending radius ≥ 150mm); tighten the joints to the specified torque to prevent loosening; after installation, perform a no-load test operation 3-5 times to confirm smooth operation without jamming before putting it into use.
Selection and Replacement Suggestions
Prioritize original equipment manufacturer (OEM) parts or parts that meet Komatsu's control/transmission standards to avoid inferior parts that may cause control delays or flexible shaft breakage due to insufficient material or precision, affecting work efficiency and safety.
If the inner core shows broken wires, the outer tube is damaged, or there is jamming or slow response in operation, it is recommended to replace the flexible shaft assembly immediately and check the fit between the connector and the actuator.
