For the Same 15 - ton Capacity, How Much Can a Wheeled Excavator Save Compared to a Crawler Excavator?
In the field of construction machinery and equipment, both 15 - ton - class wheeled excavators and crawler excavators are widely used. Although both possess strong operational capabilities, there are cost differences in various aspects. It's worth delving into exactly how much a wheeled excavator can save compared to a crawler excavator.
Purchase Cost
Generally, wheeled excavators have a certain advantage in purchase cost. The traveling mechanism of a wheeled excavator is relatively simple and does not require the complex and expensive crawler system like that of a crawler excavator. For the same 15 - ton class, the market price of a wheeled excavator is usually 10% - 20% lower than that of a crawler excavator. Taking common brands in the market as an example, the price of a new 15 - ton crawler excavator may range from 800,000 to 1,000,000 yuan, while the price of a wheeled excavator is approximately between 650,000 and 800,000 yuan. Purchasing a wheeled excavator can save around 150,000 to 200,000 yuan.
Transfer Cost
One of the greatest advantages of a wheeled excavator lies in its convenient transfer, which can save a significant amount of transfer costs. When a crawler excavator needs to be transferred, it has to be transported by a flatbed trailer. The trailer cost varies according to the transportation distance. For short - distance transportation (within 50 kilometers), it may cost 2,000 - 3,000 yuan, and for long - distance transportation (over 200 kilometers), it may be as high as 5,000 - 10,000 yuan or even more. However, a wheeled excavator can move on its own. During transfer, it only consumes fuel and incurs a small amount of labor costs. Calculated based on a fuel consumption of 40 liters per 100 kilometers and a diesel price of 7 yuan per liter, the fuel cost for a 200 - kilometer transfer is only about 560 yuan. Compared with a crawler excavator, a long - distance transfer can save several thousand yuan.
Maintenance Cost
The tracks of a crawler excavator wear out relatively quickly when operating in complex terrains. The cost of replacing a set of tracks is approximately 20,000 - 30,000 yuan, and the service cycle is relatively short, perhaps only 1 - 2 years. Although the tires of a wheeled excavator also experience wear, the replacement cost is relatively lower. The cost of replacing a set of tires is about 10,000 - 15,000 yuan, and the service cycle is relatively longer. At the same time, the traveling system of a crawler excavator is complex in structure, resulting in high maintenance difficulty and cost. In contrast, a wheeled excavator is relatively simple in this regard, and the maintenance cost is also reduced. Roughly estimated, in terms of maintenance costs, a wheeled excavator can save 10,000 - 20,000 yuan per year compared to a crawler excavator.
In conclusion, for the same 15 - ton capacity, wheeled excavators have obvious advantages over crawler excavators in terms of purchase, transfer, and maintenance costs. Over the long term, wheeled excavators can save considerable costs for construction operations.
