1.5 ton mini excavator: revealing its outstanding technical parameters

[DIG-DOG]

In today's diverse engineering construction scenarios, 1.5-ton mini excavators have gradually emerged with their compactness, flexibility and powerful performance. Behind this, a series of outstanding technical parameters support its efficient operation. Next, let's take a closer look at the impressive technical parameters of the "1.5-ton mini excavator".

1. Power system parameters: the core of high efficiency and stability

Engine power: 1.5-ton mini excavators are usually equipped with high-performance engines with a power of about 10-15 kilowatts. For example, a well-known brand of 1.5-ton mini excavator is equipped with a diesel engine rated at 12 kilowatts. This power output may seem small, but it can provide ample power for excavation operations while ensuring stable operation of the equipment. When excavating earthwork at a small construction site, such an engine power is enough to drive the excavator's working device to quickly and powerfully cut into the soil and complete the excavation task. Compared with similar but lower-power equipment, it can significantly improve excavation efficiency and shorten the construction period.

Torque output: In addition to power, the engine's torque output is also critical. Generally speaking, the engine of a 1.5-ton mini excavator can output a large torque in the low speed range, and the common torque value is 60-80 Nm. This high torque characteristic allows the excavator to easily cope with hard soil or heavy-load excavation. When digging tree pits in an orchard, encountering situations where tree roots are entangled and the soil is relatively compact, the powerful torque can ensure that the excavator bucket breaks the soil smoothly without being stuck due to insufficient power, ensuring the continuity and efficiency of the operation.

2. Working device parameters: guarantee of precise operation

Digging force: The digging force of a 1.5-ton mini excavator is an important indicator to measure its operating capacity. Usually, its digging force of the digging arm can reach 8-12 kN, and the digging force of the bucket is about 10-15 kN. Taking a popular model as an example, its bucket digging force reaches 13 kN, which means that it can easily dig all kinds of ordinary soils, and even some slightly weathered rocks can be effectively crushed and excavated. In the small-scale pipeline laying project of municipal engineering, it is necessary to quickly dig out a groove that meets the specifications. The digging force can enable the excavator to quickly complete the digging task, and the wall of the excavated groove is neat, without too much subsequent finishing, which greatly improves the quality and progress of the project.

Digging radius and depth: In the working device parameters, the digging radius and depth directly affect the operating range of the excavator. Generally, the maximum digging radius of a 1.5-ton mini excavator can reach 4-5 meters, and the maximum digging depth is between 2-3 meters. For example, in the construction process of a small landscape pond, a pond of a specific size needs to be dug. A mini excavator with such digging radius and depth parameters can accurately dig out the shape and depth of the pond that meets the design requirements within a limited construction site, meeting the strict requirements of landscape engineering for the accuracy and range of excavation operations.

3. Walking system parameters: the key to flexible movement

Walking speed: The 1.5-ton mini excavator has a flexible walking speed adjustment function. Its walking speed is generally between 2-4 kilometers per hour, divided into high and low speed gears. In a flat construction site, switching to high gear allows the excavator to move quickly to the work site, saving time; in narrow spaces or work scenarios that require precise positioning, low gear can provide stable and slow movement, allowing operators to accurately control the position of the excavator. In indoor decoration and demolition projects, narrow spaces require the excavator to move slowly and accurately. At this time, the walking speed of the low gear can well meet this demand and avoid unnecessary damage to the surrounding structures.

Track ground pressure ratio: Since 1.5-ton mini excavators often need to operate under different ground conditions, the track ground pressure ratio becomes an important parameter. The track ground pressure ratio of this type of excavator is usually controlled at 20-30 kPa. The low ground pressure ratio allows the excavator to travel stably on soft ground, such as sand and wetlands, and is not easy to sink. When performing soil improvement operations in agricultural greenhouses, the soft soil cannot withstand large pressures, and the 1.5-ton mini excavator can shuttle freely in the greenhouse with its suitable track ground pressure ratio, successfully complete excavation and plowing, and protect the ground structure in the greenhouse.

Fourth, hydraulic system parameters: support for efficient transmission

Hydraulic pump flow: The hydraulic system of the 1.5-ton mini excavator is the key to its efficient operation. The hydraulic pump flow is generally 20-30 liters/minute, which can provide stable and sufficient hydraulic power for the working device and the travel system. When the excavator performs rapid excavation, sufficient hydraulic pump flow can ensure that the bucket rises and falls quickly and rotates, increasing the excavation frequency. In small earthwork projects, high-frequency excavation actions can speed up the transportation of earthwork and cooperate with subsequent transport vehicles to achieve efficient earthwork operation processes.

System working pressure: The working pressure of the hydraulic system is also an important factor affecting the performance of the excavator. The system working pressure of a 1.5-ton mini excavator is usually between 16 and 20 MPa. The higher working pressure enables the hydraulic system to output powerful power to drive the working device to complete high-intensity excavation operations. When facing hard frozen soil or relatively solid construction waste, the system working pressure can ensure that the bucket has enough power for crushing and excavation, showing the strong adaptability of the 1.5-ton mini excavator under complex working conditions.

The 1.5-ton mini excavator achieves efficient, precise and flexible operation performance through its outstanding technical parameters in power system, working device, travel system and hydraulic system. Whether in small construction sites, municipal engineering, agriculture, gardening and other fields, these technical parameters make it an indispensable and effective equipment, providing solid technical support for various engineering construction.
