Flexible Double Universal Joint Drive Shaft Telescopic Boom Forklift Drive Shaft
1. Product Overview:
The double universal joint drive shaft for telescopic boom forklifts is a core power transmission component specially designed for telescopic boom forklifts (such as aerial work forklifts and multi-functional loading and unloading equipment). It is suitable for working scenarios that require frequent telescoping and lifting, deflection at multiple angles, and high-precision positioning. It adopts a double cross-axis universal joint structure, combined with high-strength materials and dynamic compensation technology. It can stably transmit power to the drive wheels or hydraulic actuators during the telescoping of the boom, the steering of the vehicle body, and the handling of loads. It can accurately compensate for the shaft system deviations caused by the deformation of the boom and the displacement of the chassis, ensuring the continuity and stability of power transmission, and improving the control precision and operation efficiency of the equipment.
2. Product Features:
High-precision Power Transmission: The nominal torque range is 1500 N·m to 17500 N·m, and the instantaneous impact torque bearing capacity reaches 200% of the nominal value, which is suitable for the needs of precise loading and unloading and aerial positioning.
Large-angle Compensation Ability: The dual universal joints work in 联动 to compensate for the deflection of multiple degrees of freedom such as the telescoping of the boom (longitudinal ±25°) and the steering of the vehicle body (transverse ±15°), ensuring uninterrupted power transmission.
Lightweight and Efficient: Through structural optimization and the design of composite materials, the inertia of the equipment is reduced, and the response speed and energy efficiency of the telescopic boom are improved.
Long Life and Maintenance-free: Pre-filled with long-lasting high-temperature resistant lubricating grease (-45℃~120℃), and the sealing system supports 1000 hours of maintenance-free operation.
Compatibility with Intelligent Monitoring: Vibration sensors or temperature monitoring modules can be optionally equipped to provide real-time feedback on the health status of the drive shaft and prevent unexpected shutdowns.
3. Product Advantages:
Precise and Reliable: The optimized design of the phase angle ensures a transmission efficiency of ≥97%, reducing energy loss and system heating.
Ultra-strong Durability: Passed 300,000 fatigue tests and a 100-hour salt spray test, and the service life is increased by 40% compared with traditional products.
Quick Maintenance: The modular structure supports the independent replacement of bearings and seals, reducing the maintenance time by 50%.
Certification and Compliance: Complies with ISO 9001, CE certification, and industry standards for logistics equipment (such as ISO 3691).
