Self-propelled wheeled platforms are mainly used in the construction industry, or used in high-altitude operations in open centers such as workshops and external walls. Some models of self-propelled wheeled platforms use floating axles or telescopic bridges to adapt to uneven air and enhance stability.

Self-propelled wheeled platforms are generally driven by fuel-fuelled engines. In recent years, many hybrid or pure electric platforms have emerged.

There are electric drive and hydraulic drive for walking, but hydraulic drive is the majority. The hydraulic drive is popular because of its large drive torque and strong air compliance. The hydraulic drive directly selects a built-in travel reducer integrated with a hydraulic plunger motor and a reducer, and has two speeds, fast and slow, to meet the requirements of the vehicle in different environments. The walking mechanism has a self-braking function when driving on a slope, and it is also equipped with a clutch installation, which can be towed when there is a problem. The steering mechanism adopts a linkage steering mechanism driven by a hydraulic oil cylinder.

The characteristic of the straight-arm wheeled aerial work platform is that the telescopic boom is directly completed by the telescopic structure to reach the predetermined height quickly. At present, the tallest straight-arm wheeled aerial work platform reaches 58 meters. Compared with the self-propelled wheeled platform, the ascent speed is faster, and it can work while walking and work in congested areas without space constraints. It has good stability, safety and reliability, and easy operation. Compared with the straight-arm wheeled aerial work platform, the crank arm wheeled aerial work platform is characterized by the ability to complete overpass operations. This application is indispensable in various aerial work.
