Hydraulic excavators are commonly used now, and hydraulic excavators are divided into wheel type and crawler type. Here is a comparison between crawler excavators and hydraulic excavators:
1. Hydraulic excavator
Hydraulic excavators use a hydraulic system that uses high-pressure fluid to drive cylinders to get work done. It has the following advantages:
1. Capable of precise positioning and control: The hydraulic system can finely adjust the flow and pressure to control the movement of the actuator, with precision and controllability.
2. Be able to work quickly: the hydraulic system has the characteristics of quick response, so that the excavator can work quickly.
3. Strong adaptability: The hydraulic excavator can use different attachments according to different work needs to meet various needs.
4. Simple maintenance: The maintenance of the hydraulic system is relatively simple.
2. Crawler Excavator
A crawler excavator is a construction machine that uses sprockets, crawlers, engines, and hydraulic control systems to realize excavation and walking. Its main advantages are as follows:
1. Able to drive on uneven terrain: Since the crawler excavator uses crawler belts to walk, it can drive on uneven or even weak terrain, and has a wider scope of application.
2. Can bear the load: the crawler excavator adopts sprockets, which have a large supporting area and can bear heavier working loads.
3. Can carry out a wide range of work: the crawler excavator can choose different working devices according to the actual situation, and can carry out a wide range of work.
4. Strong impact resistance: During the excavation process, the crawler excavator can well resist the impact force, can work under complex conditions, and has higher reliability.
3. Crawler excavators and hydraulic excavators are two common construction machinery and equipment, and they both have unique advantages and characteristics. Here is a comparison between them:
exercise method
Crawler excavators use crawlers as the way of movement, which has better stability and carrying capacity, and is suitable for working on uneven terrain. Hydraulic excavators use wheels or crawlers as a means of movement, which is more suitable for working on flat ground.
work efficiency
Hydraulic excavators can achieve more efficient operations due to the use of hydraulic systems. They can move and rotate quickly, improving work efficiency. Crawler excavators are more suitable for large earthworks due to their stability and carrying capacity.
scope of application
Hydraulic excavators are usually used in occasions that require frequent movement, such as urban construction and road construction. The crawler excavator is suitable for occasions requiring large-scale earthworks such as mines, water conservancy, and agriculture.
maintenance cost
Hydraulic excavators generally require more frequent maintenance and servicing because of their hydraulic systems. The crawler excavator is relatively low maintenance cost due to its simple structure.
Environmental adaptability
Track excavators perform better on muddy, rough or steep terrain. Hydraulic excavators, on the other hand, are more suitable for working on flat or slightly sloped terrain.
In general, crawler excavators and hydraulic excavators have their own unique advantages and scope of application. Which device to choose depends on the specific project needs and environment.
3. Comparison between hydraulic excavators and crawler excavators
1. Comparison of working efficiency: The response speed of hydraulic excavators is faster than that of crawler excavators, so when doing some light work, hydraulic excavators will be more efficient. When carrying out larger and heavier work, crawler excavators are naturally more suitable due to their strong load-bearing capacity and impact resistance.
2. Adaptability comparison: Hydraulic excavators can perform various tasks such as loading and unloading and ramming by replacing different attachments, while crawler excavators need to replace matching equipment to replace attachments, so they are relatively inflexible.
3. Economic comparison: the price of hydraulic excavators is relatively higher, while crawler excavators are relatively cheap. However, hydraulic excavators have a larger scope of application and higher work efficiency, and their service life will be longer.
To sum up, hydraulic excavators and crawler excavators have their own advantages and disadvantages. When choosing, it is necessary to make a reasonable choice according to the needs of the work, combined with their respective performance and characteristics.
