Series SE/PE Slewing Drive
SE/PE series slewing drives are commonly used in engineering machinery and construction equipment for rotating equipment such as excavators, cranes, rotary drilling rigs, etc. These drives are powered by hydraulic or electric systems to achieve the rotary motion of the equipment. SE series slewing drives generally feature high torque, high load-bearing capacity and stability to meet the needs of heavy machinery.
This system provides a high reduction ratio and is suitable for applications requiring high torque and low speed rotation, such as lifting equipment. It provides high precision and helps stabilize rotation and position control. In addition, the worm drive usually does not reverse rotation when it stops rotating and is self-locking, which can be used to prevent the load from sliding or rotating. Widely used in industrial and mechanical applications.
The SE/PE Series is a rugged, enclosed worm gear rotary drive that is compact and suitable for applications where space is limited and speeds are less than 1 RPM. The helical shape of worms and worm gears provides high transmission accuracy, making them useful in applications requiring stable rotation and position control.
Main Features:
- The design form of worm gear has high static load capacity
- Accuracy and clearance can be customized
- 14 product specifications
- Standard sealing and grease filling
- Suitable for harsh environmental conditions such as dust
- Support customized processing
- Main applications: photovoltaic solar energy, aerial work platforms, truck cranes, marine cranes
SE/PE series slewing drives play an important role in aerial work vehicles. They provide a more flexible working environment and wider operating range by rotating equipment. The following are some specific application examples of slewing drives on aerial work vehicles:
- Body rotation: The bodies of some aerial work vehicles are also equipped with a slewing drive system, which can realize the rotation of the entire vehicle. This allows the work vehicle to cover a wider work area without moving, improving efficiency.
- Precise Positioning: The slew drive allows the operator to make very precise positioning adjustments at height. This is important for jobs that require a high degree of precision, such as repair, installation or construction tasks.
In summary, slew drives add mobility and flexibility to aerial work vehicles, allowing operators to complete a variety of aerial work tasks more safely and efficiently.
