Customization Double U Joint Driveshaft High Strength For Truck Mounted Crane

1. Product Overview:
The double universal joint drive shaft for truck-mounted cranes is a core component specifically designed for the power transmission system of wheeled cranes. It is suitable for the high-torque and multi-angle power transmission requirements in both the vehicle driving and lifting operation modes. It adopts a double-cardan universal joint structure, combined with high-strength materials and dynamic compensation technology. It can stably transmit power in complex working conditions such as driving on rough roads, telescoping the boom, and slewing operations. It can accurately compensate for the shafting deviations caused by the deformation of the vehicle frame, the lifting of the outriggers, and the deflection of the boom, ensuring the driving safety and the reliability of the lifting operation.

2. Product Features:
Dual-mode Adaptability: It takes into account the transmission requirements of vehicle driving (high speed and low torque) and lifting operation (low speed and high torque), and supports seamless switching.
Large-angle Compensation: The two universal joints work together to compensate for the multi-directional angular deviations (radial ±15mm, axial ±8°) caused by the pitching and slewing of the boom and the tilting of the vehicle body.
Impact Resistance: The instantaneous impact torque bearing capacity reaches 300% of the rated value, which is suitable for extreme working conditions such as heavy-duty hoisting and emergency braking.
Lightweight Design: Through structural optimization and the use of composite materials, it reduces the weight by 20% to 25% compared with the traditional shaft, improving the fuel economy and mobility of the crane.

3. Product Advantages:
High Reliability: Passed 100,000 fatigue tests and bench impact tests, meeting the standard of QC/T 29117 "Technical Conditions for Truck-mounted Cranes".
Precise Transmission: The optimized design of the phase angle, with a transmission efficiency of ≥98%, reduces energy loss and system heating.
Long Service Life and Maintenance: The permanently lubricated bearings and replaceable seals extend the maintenance cycle to 1000 hours.
Certification Compatibility: It complies with ISO 9001 and CE certifications, and the GB/T 26408 special certification for construction machinery can be optionally configured.

4. Technical Parameters:

Maximum Instantaneous Impact Torque 16000 N.m
Operating Temperature -45℃ - +120℃
Weight Optimization 20% - 25% weight reduction compared with the traditional design

5. Application Scenarios:
It is suitable for various mechanical vehicles such as the driving system of wheeled cranes, the power transmission of lifting operations, emergency rescue equipment, and special modified vehicles.

6. Customization Requirements:
Modular Design: It supports customization of length, interface, and material, and can quickly adapt to the requirements of different devices.
