Caterpillar type is strong and easy to climb. The wheels are mobile and can do frequent walking work. There is stronger than the wheel track
Crawler excavator is widely used in the market, and wheeled excavator is mainly used in small municipal engineering
This is mainly focused on the chassisCaterpillar: advantage: the ground area, so in the mud, wetlands and other easy to get into a good place, because the excavator itself weight, so that the excavator can go more widely, another crawler is a metal products, qualified in the mines or bad conditions can also place, off-road ability the production of low cost, small investment.Disadvantages: another is mobility is not good, the highest design speed of only 5-7KM/H, long distance dependent mobile vehicleWheeled: advantages: small investment, quick action, the average speed can reach 40-50KM/HDisadvantages: narrow range of use, mostly road or city works, can not enter the mines or muddy areas, poor climbing capacity, high production costs, large investmentSo now most of the excavators are tracked
