Crawler dumper

Types of Crawler Dumpers

Crawler dumper, also known as tracked dumpers, are versatile and robust machines commonly utilized in construction, landscaping, mining, and agricultural sectors. They are designed to transport bulk materials effortlessly, even in challenging terrains where wheeled vehicles may struggle. Understanding the different types of crawler dumpers can aid in selecting the right one for specific business needs.

• High-Swivel Crawler Dumper

  This type of crawler dumper features a high-swivel design that allows it to rotate nearly 360 degrees on its tracks. This functionality significantly reduces the need for extensive job site maneuvering, making it ideal for working in confined areas such as urban construction sites or densely landscaped environments. The high-swivel crawler dumper can efficiently dump materials in any direction without needing precise repositioning, enhancing productivity and operational efficiency.

• Articulated Crawler Dumper

  This crawler dumper is characterized by its articulated joint between the cabin and the dump box. The articulation permits the crawler dumper to pivot in a similar way to a hinge, enhancing its maneuverability, mainly when navigating tight spaces or complex landscapes. Furthermore, articulated crawler dumpers are generally more stable on uneven terrains, minimizing the risk of tipping over, which can be advantageous when operating in rugged or hilly areas.

• Hydraulic Crawler Dumper

  Hydraulic crawler dumpers use hydraulic systems to control critical functions such as lifting the dump box and operating the driving system. The hydraulic system's power and precision make these dumpers suitable for heavy-duty tasks, such as transporting large volumes of materials in mining or large-scale construction. Additionally, hydraulic dumpers often offer smooth and adjustable dump box lifting operations, allowing for accurate and efficient material unloading.

• Mini Crawler Dumper

  Mini crawler dumpers are compact and lightweight versions designed for smaller-scale operations or projects requiring minimal disturbance to the surrounding environment. Despite their size, mini crawler dumpers retain the fundamental features and capabilities of larger models, including tracked driving systems and dump boxes. Their compact design allows them to access narrow paths, gates, and confined work areas, making them ideal for tasks like interior renovations, landscaping, and horticultural operations.

Specification and Maintenance of Crawler Dumpers

The specifications of crawler dump trucks vary depending on the model. Here are the general specifications:

• Carrying Capacity

  The carrying capacity of the crawler dumper is the most important factor to consider when choosing a crawler dumper for a specific task. Select a crawler dumper with a carrying capacity that suits the requirements of the project or business. Crawler dumpers with high carrying capacities are more difficult to transport and have a higher fuel consumption rate. The carrying capacity of the crawler dumper ranges from 0.5 tons to 3.5 tons.

• Engine Power

  Crawler dumpers have different engine powers, depending on the model. The engine power of a crawler dumper ranges from 15 to 55 kW. A crawler dumper with higher engine power can carry more loads but is more expensive and difficult to operate.

• Overall Dimension

  The overall dimension of the crawler dumper includes the length, width, and height of the dumper. A crawler dumper with a smaller overall dimension has a higher maneuverability, making it suitable for small and crowded workspaces. The overall dimension of the crawler dumper is determined by the model. However, the overall dimension of a crawler dumper is approximately 2600-3800 mm in length, 1100-1600 mm in width, and 1400-2000 mm in height.

• Track Width and Length

  The tracks of the crawler dumper allow it to travel on rough terrains and provide stability. The track width and length of the crawler dumper also affect its maneuverability and loading capacity. The tracks of the crawler dumper are approximately 230-400 mm in width and 1000-1700 mm in length.

• Hinge Pin Height

  The hinge pin height is the point where the dumper box pivots during loading and unloading. The hinge pin height is important since it determines how high the box can lift during unloading. The hinge pin height of the crawler dumper is approximately 1200-1800 mm.

• Dumping Angle

  The dumping angle of the crawler dumper is the angle at which the dumper box pivots during unloading. A crawler dumper with a higher dumping angle can unload its load quickly and efficiently. The dumping angle of a crawler dumper is approximately 45-60 degrees.

Maintaining crawler dumpers is important to improve their durability, prevent accidents, and enhance their performance. Here are some general tips on how to maintain a crawler dumper:

• Read the manual and follow the manufacturer's instructions on how to maintain the crawler dumper.
• Change the engine oil and filter regularly, depending on the recommendations of the operating hours or maintenance schedule.
• Check the air filter and clean it regularly to ensure that the engine of the crawler dumper has clean air.
• Check the hydraulic oil level and top it up if necessary. Also, change the hydraulic oil and filter depending on the recommendations of the manufacturer's manual.
• Check the tracks for any signs of wear or damage. Replace the tracks of the crawler dumper if they are worn out or damaged.
• Inspect other parts of the crawler dumper for wear and damage. Replace or repair the parts if necessary.
• Ensure that all the bolts and nuts of the crawler dumper are tight.
• Check the tire pressure and inflate the tires of the crawler dumper if they are not inflated to the recommended level.
• Store the crawler dumper in a dry place to avoid damage to the electronics and reduce the risk of rust.
• Use the crawler dumper for the intended purpose to avoid excessive wear and damage to the machine.

How to choose crawler dumpers

Picking the right crawler dumper requires careful consideration of several factors:

• Carrying Capacity

  The crawler dumper's load capacity should be compatible with the business's transportation requirements. Smaller crawler dumpers, with an operational capacity of around 1.0 tonnes, are appropriate for narrow access or constrained locations. In contrast, bigger models, with a capacity of up to 3.5 tonnes or more, provide enhanced effectiveness in bulk material transportation.

• Engine Power

  Consider the crawler dumper's engine power in relation to the anticipated terrain's difficulty. More powerful engines are necessary for traversing steep inclines or rough terrain, ensuring consistent performance without compromising efficiency.

• Track Width and Length

  Crawler dumpers have different track dimensions that influence their stability and ground effect. Models with broader and longer tracks provide superior stability and lower ground pressure, making them appropriate for marshy or fragile terrain. Conversely, narrower tracks are advantageous in locations requiring agility and tight turning capabilities.

• Loading and Unloading Efficiency

  The crawler dumper's design features, such as the type of dumping mechanism (e.g., front, rear, or side), loading and unloading speed, and overall efficiency, should be considered. Features such as high lift height and fast cycle times can significantly reduce loading and unloading time, enhancing overall operational efficiency.

• Operator Comfort and Safety

  When selecting a crawler dumper, consider the features that enhance operator safety and comfort. Features like ergonomic seats, adequate visibility, and safety measures such as rollover protection structures (ROPS) are essential. An attentive and comfortable operator contributes to productivity and ensures safe operation of the equipment.

• Maintenance and Serviceability

  Evaluate the crawler dumper's maintenance needs, such as the accessibility of key components, the frequency of routine maintenance tasks, and the availability of spare parts. Choosing models with easy serviceability can minimize downtime and lower overall equipment maintenance costs.

• Fuel Efficiency

  In an era where environmental awareness is crucial, fuel efficiency plays an important role. Compare the fuel consumption rates of different crawler dumper models. More fuel-efficient machines not only reduce operating costs but also minimize the carbon footprint, making them environmentally friendly.
