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).
