What is the speed of second – hand track – type excavators? Second-hand Track-type Excavator
As a supplier of second – hand track – type excavators, I often encounter customers who are concerned about the speed of these machines. The speed of a second – hand track – type excavator is a multi – faceted parameter that involves both traveling speed and working speed, and it is crucial for projects, affecting work efficiency and cost – effectiveness.
Traveling Speed
The traveling speed of a second – hand track – type excavator mainly refers to the speed at which the excavator moves from one point to another on the construction site or between different work areas. Generally, the traveling speed of track – type excavators varies depending on the model and power configuration.
For small – sized second – hand track – type excavators (usually with an operating weight of less than 10 tons), their traveling speed is relatively lower. On average, the maximum traveling speed can reach about 2 – 5 kilometers per hour. These small excavators are often used in narrow construction sites or for tasks that require high flexibility, such as indoor demolition or small – scale landscaping projects. The relatively low traveling speed is also in line with their working scenarios, as they usually do not need to move long distances at high speed.
Medium – sized second – hand track – type excavators (with an operating weight between 10 – 30 tons) have a more balanced traveling speed. Their maximum traveling speed typically ranges from 3 – 6 kilometers per hour. These excavators are widely used in general construction projects, such as building foundations, road construction, and earth – moving work. The speed allows them to move efficiently within the construction site while still maintaining stability.
Large – sized second – hand track – type excavators (with an operating weight over 30 tons) usually have a maximum traveling speed of about 4 – 7 kilometers per hour. Although these large machines are bulky, their high – power engines and advanced track systems enable them to move relatively smoothly on the construction site. However, due to their large size and heavy weight, they still need to move at a moderate speed to ensure safety.
It should be noted that the actual traveling speed of a second – hand excavator may be affected by many factors. For example, the condition of the tracks is very important. Worn – out tracks can reduce the traction force, resulting in slower traveling speed. The terrain of the construction site also has a significant impact. On soft soil, sandy ground, or uneven terrain, the traveling speed will be much lower than on flat and hard surfaces. Moreover, the performance of the engine and the hydraulic system of the second – hand excavator can also affect its traveling speed. If the engine power is insufficient or the hydraulic system has problems, the traveling speed will decrease.
Working Speed
The working speed of a second – hand track – type excavator is mainly reflected in the action speed of its working devices, such as the boom, arm, and bucket. This speed is measured by the time it takes for these components to complete a series of standard actions, such as digging, lifting, and unloading.
The boom lift – up speed is an important indicator of the working speed. A fast boom lift – up speed means that the excavator can quickly lift the dug materials to a high position, which is very important for transferring materials to trucks or for high – altitude construction work. For different models of second – hand track – type excavators, the boom lift – up time can range from a few seconds to more than ten seconds. Small – sized excavators usually have a relatively faster boom lift – up speed because their lighter weight allows the hydraulic system to drive the boom more easily.
The arm extension and retraction speed also affects the working efficiency. A fast arm movement can quickly adjust the digging position, reducing the time required for each digging cycle. In general, modern second – hand track – type excavators are designed to have a relatively high arm movement speed to meet the needs of high – efficiency construction.
The bucket rotation speed is another factor that affects the working speed. A high – speed bucket rotation can quickly change the direction of the bucket, which is very useful for precise digging and material placement. Second – hand excavators with advanced hydraulic control systems usually have a smooth and fast bucket rotation function.
Similar to the traveling speed, the working speed of a second – hand excavator can be influenced by various factors. The hydraulic system is the key to the working speed. A well – maintained hydraulic system with sufficient oil pressure and flow can ensure the normal operation of the working devices at a high speed. The wear of the valves and cylinders in the hydraulic system will reduce the working speed. In addition, the operator’s skills also play an important role. A skilled operator can use the excavator’s functions to the fullest, optimizing the working process and improving the overall working speed.
Why Speed Matters
The speed of second – hand track – type excavators is of great significance for construction projects. In terms of efficiency, higher traveling and working speeds can reduce the time required to complete a project. For example, in a large – scale earth – moving project, a fast – moving excavator can quickly transfer between different digging areas, and a high – speed working excavator can complete each digging cycle in a shorter time, thus speeding up the overall progress of the project.
From a cost – effectiveness perspective, an excavator with appropriate speed can save labor and fuel costs. If an excavator has a slow speed, more time and labor will be required to complete the same amount of work. Moreover, a machine that operates at an appropriate speed is usually more fuel – efficient, as it does not need to consume excessive energy to maintain slow – paced operations.
Assessing the Speed of Second – Hand Excavators
When I help customers select second – hand track – type excavators, I stress the importance of assessing the speed of the machines. Firstly, we need to check the technical documentation of the excavator. The data in the documentation, such as the maximum traveling speed and the standard working cycle time, can provide a basic reference. However, it should be noted that the actual speed may deviate from the values in the documentation due to the wear and tear of the machine.
Secondly, on – site testing is essential. We conduct on – site tests of the traveling speed on different terrains to evaluate the actual performance of the excavator. During the working speed test, we observe the movement of the boom, arm, and bucket to check if they can operate smoothly and quickly. We also pay attention to the response time of the control system. A fast – responding control system can ensure that the operator’s commands are executed in a timely manner, improving the overall working speed.
Making the Right Choice
As a second – hand track – type excavator supplier, I understand that different construction projects have different requirements for the speed of excavators. For urgent projects that require high – speed operation, customers may need to choose excavators with relatively high traveling and working speeds. However, for some projects with limited space or high – precision requirements, the focus may be more on the flexibility and controllability of the excavator rather than the absolute speed.
When customers are considering purchasing a second – hand track – type excavator, they should not only focus on the speed but also consider other factors such as the overall condition of the machine, the after – sales service, and the price. A machine with high speed but poor overall condition may bring more maintenance problems in the future, which will affect the normal progress of the project.
In conclusion, the speed of second – hand track – type excavators is an important parameter that needs to be carefully considered. Whether it is the traveling speed or the working speed, they both have a direct impact on the efficiency and cost – effectiveness of construction projects.
