GUOMAO GTR-T Walking Drive Reducer
The GUOMAO GTR-T Walking Drive Reducer is a professional planetary track drive unit specially developed for mobile walking machinery and engineering crawler equipment. Adopting multi-stage planetary reduction structure, high-strength alloy steel gear forging and integral high-rigidity sealed housing design, this series featuresultra-wide speed ratio range, low-speed high-torque output, strong impact resistance, compact outer ring rotation structure and excellent environmental adaptability. Specially optimized for frequent start-stop, forward and reverse walking, bumpy road condition impact and continuous variable-load operation of mobile engineering equipment, it effectively solves common problems of traditional walking drives such as insufficient starting torque, poor impact resistance, easy water and dust ingress and short service life. With professional walking mechanism matching performance and reliable off-road working condition durability, it has become the core dedicated transmission supporting product for various crawler-type engineering and mobile equipment.
Power (kW): 0.18–90kW
Speed Ratio: 14–1200
Max. Output Torque: 35 kN·m
2.1 Ultra-Wide Speed Ratio Coverage for Full-Speed Walking Adaptation
The GTR-T walking drive series has an ultra-wide speed ratio range from 14 to 1200, covering low-speed heavy-torque climbing and high-speed flat walking working conditions. It can realize flexible switching of fast traveling, slow crawling, precise positioning and heavy-load starting, fully meeting the diversified walking speed regulation requirements of small, medium and large mobile crawler equipment. The ultra-large speed ratio span avoids the limitation of single walking speed of traditional walking reducers, greatly improving equipment maneuverability and site adaptability.
2.2 35kN·m High Starting Torque & Strong Overload Impact Resistance
With a maximum output torque of 35kN·m, the GTR-T reducer provides super strong starting torque reserve for heavy-load walking equipment. Adopting multi-planetary gear simultaneous meshing load-sharing structure, it features uniform force bearing and strong instantaneous overload resistance. Core gears are made of high-strength alloy steel through carburizing, quenching and precision grinding, with high hardness and excellent anti-fatigue performance. It can effectively resist impact load generated by bumpy road surfaces, slope climbing, sudden start-stop and steering walking, ensuring stable and powerful output without slipping or stalling during heavy-load walking.
2.3 Special Outer Rotation Compact Structure & High Integration
Different from fixed-shaft ordinary reducers, the GTR-T series adopts outer ring rotation walking drive structure, featuring compact overall volume, ultra-thin body and high integration. It can be directly installed inside the crawler wheel hub, saving external installation space and optimizing the overall mechanical structure of walking equipment. The integrated high-rigidity housing effectively resists external extrusion and collision deformation, ensuring structural stability during long-term off-road walking operation.
2.4 Excellent Sealing Performance & Super Harsh Environment Adaptability
Aiming at the complex working conditions of mud, water splashing, dust and gravel impact of engineering walking equipment, the GTR-T series adopts upgraded multi-layer heavy-duty sealing structure and professional waterproof and dustproof design. It effectively prevents mud, rainwater, dust and sundries from entering the interior, avoiding gear wear, oil leakage and transmission failure caused by harsh environment. It can operate stably for a long time in outdoor open-air, muddy, wet and dusty construction sites, with extremely low failure rate and strong field durability.
2.5 Low-Speed Stable Operation & Precise Walking Control
Through optimized gear tooth profile correction and meshing clearance matching, the whole machine runs smoothly with low vibration and low noise. It has sensitive speed response and stable torque output, effectively solving the problems of jitter, offset and unstable walking of traditional walking reducers during low-speed crawling and precise steering. It ensures straight walking and accurate positioning of mobile equipment, improving construction accuracy and operation stability.
2.6 Strong Versatility & Low Field Maintenance Cost
The GTR-T walking drive supports diversified matching with hydraulic motors and electric motors, with universal standard installation interface and strong interchangeability. It is widely compatible with various crawler walking equipment, convenient for on-site assembly, replacement and maintenance. The internal structure is durable with few vulnerable parts, which greatly reduces daily maintenance frequency and later comprehensive operation cost, with outstanding field applicability and cost performance.
