Both wheeled and crawler excavators are very popular excavating equipment in construction projects, but many customers do not know what kind of excavators are suitable for their own situation. The following will introduce the advantages and disadvantages of the two in detail to help machine owners and friends according to the working conditions Choose the most suitable equipment, so that your engineering work can achieve twice the result with half the effort.
wheeled excavator
The walking mechanism of wheeled excavators is tires. Under normal circumstances, you can choose the standard vacuum rubber tires. However, in high temperature environments, solid tires have better performance and can cope with harsher working environments.
wheeled excavator
Advantages: flexible maneuvering, convenient transition, low cost, low fuel consumption, fast walking speed, little damage to the ground surface, rubber tires also have shock absorption and buffering functions;
Disadvantages: poor passing performance, poor load-bearing capacity, and poor stability (but it can be equipped with eight-character outriggers to improve stability);
Applicable working conditions: hard pavement, such as cement floor, road, lawn.
crawler excavator
The walking mechanism of crawler excavators is crawler, and there are also two types of chassis: rubber and steel crawler. The rubber crawler chassis can carry a 10-ton fuselage, with low noise and little damage to the ground surface. The steel crawler chassis can carry a larger load. Large crawler excavators are basically equipped with a steel crawler chassis.
crawler excavator
Advantages: strong off-road ability, strong passing ability, strong load-bearing capacity, strong climbing ability, good stability and durability;
Disadvantages: relatively bulky, difficult to control, slow walking speed, high cost, high fuel consumption, fast wear of parts, and great damage to the ground surface;
Applicable working conditions: soft and wet ground, such as mud, mud, swamp.
comprehensive comparison
After the above analysis of the advantages and disadvantages of wheeled excavators and crawler excavators, the comparison of important parameters as shown in the figure below can be obtained. Friends of the machine owners can comprehensively consider according to their own working conditions and choose the most suitable equipment.
How to judge which model is suitable for you?
two criteria:
1. Look at funds
Usually, the investment of crawler excavators is higher than that of wheeled excavators. Of course, funds are only one aspect of model selection, and the most critical factor is the ability to improve work efficiency.
2. Look at the project
a. Look at the road conditions of the project, if the road conditions are better, choose the wheel type, and if you pursue off-road, choose the track;
b. Depending on the transition frequency of the project, most of the transitions are wheeled, and fixed sites are acceptable;
c. Depending on the size of the project, whether the time is limited or not, if the project is large and the time is tight, choose the crawler; if the project is average and the time is loose, choose the wheel type.
