1. Product Description
The grab crane wheel-side universal drive shaft assembly is a core driving component for grab cranes used in ports, docks, and ship loading/unloading scenarios. Specifically designed for multi-grab cooperative operations, it efficiently transmits power to the traveling wheel set while accommodating the dynamic stability requirements of frequent steering, sudden load changes, and complex terrain. Its high-torque, impact-resistant features and compact structure ensure precise control and continuous operation during heavy-load grabbing, rapid movement, and multi-angle adjustments, making it a key component for enhancing loading/unloading efficiency and safety.
2. Product Features
(1) Heavy-Duty Anti-Torsion Design
Forged from high-strength alloy steel and precision-ground with surface hardening treatment, it boasts a tensile strength of ≥1,200 MPa and a dynamic torque capacity of 30,000 N·m, suitable for full-load impact conditions.
(2) Multi-DOF Universal Drive
Equipped with a double universal joint structure, supporting a ±45° deflection angle to adapt to uneven tracks and dynamic wheel displacement caused by grab load swings.
(3) All-Weather Sealing Protection
Features a multi-lip redundant sealing system (rubber lip seal + dust cover) with IP68 protection, resistant to seawater corrosion, salt spray erosion, and dust ingress. Internally lubricated with long-lasting water-resistant grease, operable in temperatures from -45°C to 120°C.
(4) Dynamic Balance Optimization
Lightweight design combined with dynamic balance calibration (residual unbalance ≤5 g·mm) reduces high-speed vibration, with noise controlled at ≤70 dB(A), extending bearing service life.

4.Applications
(1) Container Handling: Adapts to high-frequency start-stop cycles, heavy-load impacts, and multi-grab cooperative operations.
(2) Bulk Cargo Grab Operations: Resists dust pollution and vibration shocks during the loading/unloading of coal, ore, and other bulk materials.
(3) Shipyard Maintenance: Corrosion-resistant design for long-term use in humid marine environments.
(4) Multi-Crane Coordination: Enables precise synchronous control for collaborative handling of oversized cargo.
5. Customization: OEM customization supported.
6.Product Advantages
(1) Impact-Resistant Redundant Design: Reinforced spline shaft and flange connection structure withstands shock loads from sudden grab unloading.
(2) Quick Maintenance Compatibility: Modular assembly design allows online lubrication without disassembly, with replacement time ≤45 minutes.
(3) Multi-Condition Adaptability: Customizable versions available, including low-temperature-resistant models (-40°C to +120°C).
