GUOMAO GTR-B Winch Drive Reducer
The GUOMAO GTR-B Winch Drive Reducer is a professional heavy-duty planetary drive unit specially designed for winch hoisting, lifting and winding mechanical equipment. Adopting multi-stage planetary deceleration structure, high-strength alloy steel precision forging process and high-rigidity integral sealed housing, this series features ultra-wide speed ratio range, stable low-speed high-torque output, excellent load holding capacity, strong anti-impact performance and reliable overload resistance. Optimized exclusively for core working characteristics such as heavy-load lifting, frequent start-stop, positive and negative winding, and static load holding of winch equipment, it effectively solves common industry pain points of traditional winch reducers, including insufficient lifting torque, poor load stability, easy slipping and low safety factor. With professional hoisting working condition adaptation and long-term heavy-load operational reliability, it serves as the preferred dedicated transmission supporting product for various engineering winches, lifting machinery and winding equipment.

Max. Output Torque: 35 kN·m
2.1 Ultra-Wide Speed Ratio Coverage for Full-Range Lifting Matching
The GTR-B winch drive series covers an ultra-wide speed ratio range of 14 to 1200, perfectly adapting to diversified hoisting demands from high-speed light-load winding to ultra-low-speed heavy-load lifting. It can flexibly realize fast rope winding, stable medium-speed lifting and precise low-speed positioning, fully matching the speed regulation requirements of small, medium and large winch equipment. The ultra-large speed ratio span breaks the limitation of single operating speed of traditional winch reducers, greatly improving the working efficiency and operation flexibility of lifting equipment.
2.2 35kN·m Super High Torque & Excellent Overload Resistance
With a maximum output torque of 35kN·m, the GTR-B reducer provides sufficient and stable torque reserve for heavy-load hoisting operations. Adopting multi-planetary gear simultaneous meshing load-sharing structure, the product realizes uniform force distribution and strong instantaneous overload resistance. Core gears are made of high-quality alloy steel, processed through strict carburizing, quenching and precision grinding, with high surface hardness, outstanding wear resistance and anti-fatigue performance. It can effectively resist instantaneous impact load during heavy-load starting, sudden braking and heavy object suspension, ensuring stable and non-attenuating torque output without slipping or stalling during long-term lifting operation.
2.3 Excellent Static Load Holding & High Safety Performance
Different from ordinary transmission reducers, the GTR-B series is structurally optimized for winch load-holding working conditions. The precise gear meshing self-locking performance and matched stable transmission structure effectively prevent the reverse slipping of the winch during static suspension and heavy-load hovering. It maintains reliable load holding state for a long time, eliminates the hidden danger of heavy object falling caused by transmission failure, and greatly improves the overall operation safety and stability of lifting equipment, fully meeting the strict safety standards of engineering hoisting operations.
2.4 Compact Integrated Structure & High Installation Adaptability
The whole machine adopts a highly integrated planetary compact layout, with small overall volume, light weight and high structural rigidity. It features simple and flexible installation modes, which can be perfectly embedded and matched with various winch drums and lifting hosts, effectively saving equipment installation space and optimizing the overall structural design of winch machinery. The integral thickened housing undergoes professional stress relief treatment to avoid structural deformation under long-term heavy tension and vibration, ensuring long-term structural stability.
2.5 Reliable Sealing & Strong Harsh Environment Adaptability
Equipped with upgraded multi-layer composite sealing structure, the GTR-B winch drive has excellent dust-proof, moisture-proof and oil-leakage-proof performance. It can operate stably for a long time in complex working environments such as outdoor open-air construction sites, dusty workshops and humid industrial sites. The high wear-resistant internal components effectively reduce component wear and failure rate under frequent alternating load operation, with strong industrial durability and long service life.
2.6 Stable Operation & Low Comprehensive Maintenance Cost
Through optimized tooth profile correction and meshing clearance calibration, the gear meshing process is smooth and stable with low vibration and low noise during operation. The whole machine has sensitive speed response and accurate power output, ensuring stable lifting and uniform winding of winch equipment. Adopting standardized modular design with fewer vulnerable parts, it simplifies daily lubrication, inspection and maintenance procedures. The universal installation interface realizes fast assembly and replacement, effectively reducing equipment downtime and long-term comprehensive operation and maintenance costs.
