Crawler type stacker is a device that uses rubber or steel tracks as walking devices to flip, crush, and mix materials through high-speed rotating rollers (equipped with flipping knives). It represents more advanced and heavier technology than wheeled vehicles.

　　1、 Main advantages and characteristics

　　1. Strong terrain adaptability and stability

　　Grounding ratio is low: The track disperses the weight of the machine over a larger contact area, allowing it to walk steadily even on soft, damp, and uneven material piles, with very little slipping or sinking.

　　Strong climbing ability: able to adapt to fermentation tanks or sites with a certain slope, and operate more reliably.

　　2. Excellent flipping efficiency and effectiveness

　　Strong power: usually equipped with high-power diesel engines or motors, with high driving torque, capable of handling materials with high viscosity, high moisture content, and high packing density (such as sludge, livestock manure, etc.).

　　Thoroughly flipping: The flipping drum is wide and the blades are dense, which can lift, disperse, and mix the materials evenly. The oxygen contact surface is large, and the fermentation is more complete.

　　Tempering function: During the flipping process, it can effectively break up clumps, evaporate water, reduce material density, and create optimal conditions for microbial activity.

　　3. Large processing capacity and continuous operation capability

　　Large working width: usually 3-6 meters, or even wider.

　　Adjustable walking speed: The forward and flipping speed can be adjusted according to the material status, achieving efficient continuous operation. The daily processing capacity of a single machine can reach thousands of cubic meters.

　　4. High degree of automation and intelligence

　　Cockpit operation: Usually equipped with a comfortable cab, centralized control, and good visibility.

　　Optional automation system: such as automatic navigation (along the fermentation tank track or GPS), remote monitoring, data acquisition (temperature, oxygen consumption, etc.), to achieve intelligent management.

　　5. Durable and sturdy, suitable for heavy-duty working conditions

　　Sturdy structure: specially designed for high-strength and highly corrosive working environments.

　　Key component strengthening: The flipping blade, bearings, and transmission system are wear-resistant, corrosion-resistant, and have a long service life.

　　2、 Limitations or characteristics that need to be considered

　　1. High initial investment cost

　　Due to its complex structure and powerful functions, the purchase price is much higher than that of wheeled turners and simple chain plate turners.

　　2. There are certain requirements for the venue

　　Although it has strong adaptability to terrain, the optimal working environment is a standard concrete fermentation tank. When working on open ground without grooves, its high efficiency advantage may not be fully realized.

　　The turning radius is relatively large, and sufficient turning space needs to be reserved.

　　3. Relatively complex maintenance

　　The crawler walking mechanism needs to be regularly inspected for tension and wear, and the maintenance cost is slightly higher than that of the wheel type.

　　Complex hydraulic and transmission systems require professional maintenance.

　　4. Poor mobility and transferability

　　The body is large and heavy, making it difficult to be easily towed and transferred by trucks like wheeled equipment. Usually requires fixed installation in different fermentation workshops or transportation using large flatbed trucks.

　　3、 Main application scenarios

　　Large scale municipal sludge treatment: treating sludge generated by urban sewage treatment plants.

　　Resource utilization of manure from large-scale breeding farms: processing manure from livestock and poultry such as cattle, pigs, and chickens.

　　Organic fertilizer standardized production plant: producing commercial organic fertilizers or bio organic fertilizers.

　　Garbage treatment plant: deals with organic waste such as kitchen waste and garden waste.

　　A brief comparison with wheeled stacker

Crawler type stacker is a high-end equipment designed for heavy-duty, continuous, and large-scale industrial aerobic fermentation engineering. Its core features are strong passability, excellent flipping quality, and huge processing capacity, making it very suitable for large-scale organic waste treatment projects with sufficient funds and long-term stable operation plans. When making a selection, it is necessary to comprehensively consider the project scale, material characteristics, investment budget, and site conditions.
