What key performance parameters should be considered when choosing hydraulic excavators for coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. needs to consider the following key performance parameters when selecting hydraulic excavators for coal mines. When choosing hydraulic excavators for coal mines, the following key performance parameters need to be considered:

1、 Engine power

The engine power determines the operational capability and efficiency of hydraulic excavators used in coal mines. Generally speaking, the higher the engine power, the stronger the working ability of hydraulic excavators used in coal mines, and they can complete larger scale projects. In the high-intensity working environment of coal mines, choosing a powerful engine can ensure the stability and durability of hydraulic excavators used in coal mines during operation.

2、 Bucket capacity

The bucket capacity refers to the capacity of the hydraulic excavator bucket used in coal mines, which directly determines the excavation capacity and loading efficiency of the hydraulic excavator used in coal mines. The larger the bucket capacity, the greater the amount of soil excavated and loaded by hydraulic excavators in coal mines, thereby improving construction efficiency. However, a large bucket capacity can also increase the weight and volume of hydraulic excavators used in coal mines, which is not conducive to operating in narrow or complex terrain. Therefore, when choosing hydraulic excavators for coal mines, the bucket capacity size should be reasonably selected based on the actual situation of the construction site and the demand for earthwork volume.

3、 Operating weight

The operating weight refers to the weight of the hydraulic excavator used in coal mines, including the weight of the body, engine, bucket and other components. The greater the operating weight, the stronger the stability and load-bearing capacity of hydraulic excavators used in coal mines, which can better adapt to various complex construction environments. However, excessive operating weight can also increase the transportation cost and energy consumption of hydraulic excavators used in coal mines. Haoyun Heavy Industry reminds that it is necessary to control the operating weight of hydraulic excavators used in coal mines as much as possible while meeting construction requirements.

4、 Walking speed

The walking speed determines the movement speed of the excavator on the construction site, which is of great significance for improving work efficiency. In coal mining operations, it is necessary to choose a hydraulic excavator with a suitable walking speed according to the size of the work site and the requirements of the operation.

5、 Rotation speed

The turning speed affects the flexibility and efficiency of hydraulic excavators used in coal mines during operation. The faster the rotation speed, the more flexible the excavator is during operation, and it can complete excavation, loading and other actions more quickly.

5、 Dig deep

The excavation depth determines the soil depth that hydraulic excavators can excavate in coal mines, which is crucial for completing excavation tasks at specific depths. In coal mining, it is necessary to select a suitable hydraulic excavator for coal mining based on the depth of the coal seam and mining requirements.

6、 Hydraulic system

The hydraulic system is the core of hydraulic excavators used in coal mines, and its performance directly affects the work efficiency and reliability of hydraulic excavators used in coal mines. It is necessary to consider the flow rate and pressure of the hydraulic pump, the stroke and thrust of the hydraulic cylinder, as well as the sealing performance and heat dissipation performance of the hydraulic system.

7、 Operating comfort

The operational comfort of hydraulic excavators used in coal mines is also an important factor in their selection. Haoyun Heavy Industry coal mine hydraulic excavators are usually equipped with user-friendly operating systems and comfortable cabins, which can reduce operator fatigue and improve work efficiency.

8、 Maintenance cost and service life

Maintenance and upkeep costs are also one of the factors to consider when choosing hydraulic excavators for coal mines. There may be differences in maintenance costs for hydraulic excavators used in coal mines of different brands and models, which need to be selected based on their own economic strength and usage needs. At the same time, it is necessary to consider the service life of hydraulic excavators used in coal mines and choose equipment that is reliable in quality and durable.
