Applications
Self-propelled articulating arm climbing car
The articulated arm aerial work vehicle is a lifting device used for aerial work. It can cross obstacles and perform aerial work. When the platform is lifted to any position, it can be operated while walking. It has a compact structure and flexible steering. Narrow passages and crowded work areas.
Concrete pump truck
Concrete is the most commonly used building material. In order to transport concrete quickly and effortlessly in a specific area, we choose to use a concrete pump truck. By rotating the swivel arm of the concrete pump truck, the nozzle of the concrete pump is aligned with the desired position to complete the delivery of concrete. The slewing bearing plays a vital role in this process. When developing and designing the slewing bearing, special attention was paid to ensuring its accuracy and robustness for conditions on construction sites around the world, reliable high tipping moments to ensure stable pump operation.
