Crawler Aerial Work Platforms: A Growing Trend In The Construction Industry
The construction industry has witnessed a surge in the use of crawler aerial work platforms, particularly crawler scissor lifts. These tracked machines provide an excellent alternative to traditional wheeled equipment and offer several advantages in various application scenarios. This article explores the reasons behind this growing trend and the key features of crawler scissor lifts.
Crawler scissor lifts boast a unique movement mode, thanks to their track system. Although not as maneuverable as wheeled scissor lifts, their track structure equips them with capabilities beyond those of their wheeled counterparts. On uneven or unhardened surfaces, muddy areas, and potholes, wheeled scissor lifts often struggle. However, crawler scissor lifts thrive in these situations due to their large attachment area and impressive obstacle-overcoming ability.
Balancing Work Environment and Cost-Performance
In construction scenarios where the ground is not under construction and multiple high-altitude operations are needed, traditional diesel off-road scissor lifts and arm-type off-road aerial work platforms can be expensive and cumbersome. Crawler scissor lifts bridge the gap between wheeled scissor lifts and off-road boom trucks, offering a balanced solution that can complete tasks effectively while saving costs.
Comparing Crawler and Wheeled Scissor Lifts
Crawler scissor lifts feature two prominent tracks on their walking mechanism, providing strong ground adhesion ability. Wheeled aerial work platforms, on the other hand, come in indoor non-marking tire scissor platforms and outdoor off-road tire platforms. Off-road scissor lifts share similarities with ordinary scissor platforms, but they have a higher chassis and stronger tire grip for outdoor operations.
Crawler scissor lifts are becoming more diverse in size, with various heights (4 to 14 meters) and wheelbase options available. Despite their relatively higher ground destructiveness compared to wheeled lifts, scissor tracks typically use rubber tracks, which are more ground-friendly.
Power Drive Options for Crawler Scissor Lifts
Crawler scissor lifts employ power drive systems similar to those found in conventional scissor lifts, with hydraulic and electric drives available. Electric drives, currently more mainstream, can be equipped with brushless DC motors, brushed DC motors, or AC motors. To ensure optimal performance, the compatibility between these motors and the crawler lift body is crucial.
Control Processes in Crawler Scissor Lifts
The control methods for crawler scissor lifts' lifting actions are comparable to those of ordinary scissor lifts. The primary distinction lies in the walking action, specifically in the forward, backward, and turning movements of the tracks. For accurate steering control, a handle on the steering axis is a key feature. Crawler walking motion control is typically achieved through speed adjustment of the tracks.
The increasing diversity of aerial work platforms has invigorated the market and contributed to the growth of the construction industry. The rising popularity of crawler aerial work platforms, such as crawler scissor lifts, demonstrates their potential for becoming an industry staple in the future.
