"Crawler Scissors lift, Rough Terrain Man Lift Advantages, Applications, and Technical Features"
Tracked models are still very common in the field of construction machinery. The most familiar one is the excavator. Thanks to its flexible two-tracks, the excavator can easily work on muddy ground and has a strong ability to overcome obstacles. Compared with Wheeled equipment has better passing ability on poor road surfaces. Since the development of aerial work platforms, all kinds of equipment have emerged, and crawler scissors have been mentioned more in today's application scenarios. This has also created opportunities in the Crawler Aerial Work Platforms market. Of course, more and more models will be invented in different scenarios, such as aerial work platform equipment used in the track, and aerial work platforms will be seen in most aerial work scenes in the future. Today, crawler aerial work platforms have a chat.
Why Use crawler scissor lift/ rough terrain man lift
What's so special about crawler scissors? Why use track scissors? What are the application scenarios of crawler scissors? With this question in mind, let's discuss it. The crawler scissors have a special movement mode. The power wheel runs with the driven wheel, and finally transmits the power to the track, which is pressed over and over to complete the walking action. The movement process of tracked scissors is not as flexible as that of wheeled scissors, and it looks a bit clumsy, and it needs destructive rotation to complete the steering, but because of this track structure, it has the ability that wheeled scissors do not have. , when encountering unhardened and uneven roads, slight potholes, and muddy places, wheeled scissors are often helpless and powerless at this time, and they cannot move when entering. Tracked scissors work under such working conditions. , Relying on the large attachment area of the track and the strong ability to overcome obstacles, it can't be more proud in this application scenario. When the ground is not under construction, multi-point high-altitude operations are required. Diesel off-road scissors and arm-type off-road aerial work platforms are expensive, and the models are large in size, which makes it difficult to work in narrow spaces. It solves the embarrassment of wheeled scissors and off-road boom trucks and achieves a balance between the working environment and cost performance. It can not only complete the task calmly but also save a fortune.
Similarities and differences between crawler scissors and wheeled scissors
The crawler scissors stand out on the walking mechanism with two crawlers and strong ground adhesion. We compare the wheeled aerial work platform with the indoor non-marking tire aerial work platform and the outdoor off-road tire aerial work platform. Ordinary conventional aerial work platforms in the industry are basically indoor non-marking tire scissors platforms. Wheeled scissors have the basic properties of vehicles, including power wheels, steering wheels, and driven wheels. The walking movement depends on the rotation of the wheels. Reducer driven, hydraulically driven, steering with hydraulic steering, differential steering and other forms. The movement mode of off-road scissors is also the same as that of ordinary scissor platforms. The main difference is that the chassis is higher and the tires have stronger grip, which is suitable for outdoor operations.
The crawler scissors are now also tending to be perfect in size. The crawler scissor platforms of various heights can be compared with ordinary scissors. The height can be from 4 meters to 14 meters, and the wheelbase can also have different sizes. The walking mode of the crawler is quite special. The power also has hydraulic power and electric driving force. The walking relies on the movement of the two crawlers in the same direction, and the steering relies on the opposite direction or differential movement of the crawlers, which is more destructive to the ground. However, compared with excavator tracks, they are much less destructive. Scissor tracks are mostly rubber tracks, which are relatively friendly to the ground, and track widths are also different. Currently, there is no complete and uniform size, and the market is constantly exploring. However, with the popularization and application of crawler scissors in trial production and reform, more excellent products will also be launched.
Power drive form of crawler scissors
The driving form of crawler scissors is basically designed with reference to the power form of ordinary scissors. There are also hydraulic drive and electric drive. The hydraulic drive track uses a pump motor oil pump to provide power for the traveling mechanism and lifting system. The crawler belt is matched with a walking motor and a pump motor. The walking motor drives forward with two crawlers, and the lifting depends on the pump motor to provide power. Compared with hydraulic drive, electric drive track is more mainstream at present. In the current era of electrification, electric drive force is also the main theme of the environment. At present, the electric drive crawler is in contact with brushless DC motors, brushed DC motors and AC motors. In terms of power drive, the power performance of these motors and the matching and coordination of the body need to be highly compatible to avoid small horse-drawn carts or large vehicles. The phenomenon of big horses and small carts.
The action control process of crawler scissors lifts
The control method of the crawler scissors is no different from that of ordinary scissors in terms of lifting. Each company will also design the hydraulic and mechanical structures on the original basis, so there is no difference in the logical control of the lifting action. The main action control lies in walking, that is, how to make the crawlers move forward, backward, and turn flexibly. Friends who have driven excavators or crawler equipment know that the two crawlers are generally controlled separately and can be adjusted for speed. It’s okay to say that the forward and backward movements of the two tracks can be synchronized by operating the handle to move forward and backward, but for the steering action, there are some tricks in it. The steering is generally the differential speed of the left and right tracks or the reverse action of the tracks. There is a key here. Originally, the handle on the ordinary scissor truck was single-axis, and it was impossible to achieve precise speed control when turning. If there is a handle on the steering shaft, it can perfectly realize the control of the steering action. Controlling the steering speed is like walking, which is the performance of the car. After a certain level has been raised, some differentiated distinctions can be made. In general, the walking motion control of the crawler is still achieved by the speed adjustment of the crawler.
