Both wheeled and crawler excavators are very popular excavation equipment in construction projects, the following is a detailed introduction to the advantages and disadvantages of both, to help you choose the most suitable equipment according to the working conditions, so that their engineering operations to achieve twice the result with half the effort.
1.Wheeled excavators
The walking mechanism of wheel excavators is tires, in general, choose the standard configuration of vacuum rubber tires can be, but in the high temperature environment, solid tires better performance, can cope with the harsher working environment
Advantages: mobile and flexible, convenient transfer, low cost, low fuel consumption, fast walking speed, little damage to the ground, rubber tires and shock-absorbing cushioning function.
Disadvantages: poor passing performance, poor load-bearing capacity, poor stability (but can be equipped with eight legs to improve stability).
Applicable working conditions: hard surface, such as concrete, highway, lawn
2.Crawler excavator
The running mechanism of crawler excavator is crawler, and there are two kinds of chassis: rubber and steel crawler. The rubber track chassis can carry 10 tons of body weight, low noise and little damage to the ground, while the steel track chassis has a greater load weight, and large crawler excavators are basically equipped with steel track chassis.
Advantages: strong off-road ability, strong passing ability, strong load-bearing capacity, strong climbing ability, good stability and durability.
Disadvantages: relatively bulky, bad handling, slow walking speed, high cost, high fuel consumption, rapid wear and tear of parts, damage to the surface.
Applicable working conditions: soft and wet ground, such as mud, mud, swamp
How to determine which model is suitable for you?
Two criteria.
1. Purchase budget
Usually crawler excavator investment is higher than wheeled excavator, of course, capital is only one aspect of choosing the model, can improve efficiency is the most critical factor.
2. Engineering working conditions
a. Look at the road conditions of the project, the road conditions are better to choose wheeled, the pursuit of off-road crawler.
b. Look at the frequency of the project transfer, transfer more choice of wheeled, fixed sites are available.
c. Look at the size of the project, time limit or not, the project volume is large, time is tight, choose crawler; general project volume, time is loose choose wheeled.
