An excavator, be it a crawler excavator or a wheeled excavator, consists of the power unit, working device, slewing mechanism, manipulation mechanism, transmission mechanism, walking mechanism, auxiliary facilities, etc. Its types can be simply divided into mini, full-sized, and large-sized, and operating weight (mass), engine power, and bucket capacity are widely considered the most important parameters you should keep your eyes on when buying them.

Brand new excavators for sale usually cost somewhere between $80,000 and $500,000. With the competition in the global excavator market, the price war between brands will also be intensifying. Resultantly, an extremely important step has been taken for the formation and development of the excavator industry.

FAQs

1. What is the power system of an excavator?
The excavator converts the chemical energy of diesel oil into mechanical energy through a diesel engine, and then converts the mechanical energy into hydraulic energy by a hydraulic plunger pump, and then distributes the hydraulic energy to each actuator through the hydraulic system (hydraulic cylinder, rotary motor and reducer, travel motor and reducer). Finally, the hydraulic energy is converted into mechanical energy by each actuator to realize the motion of the working device, the rotary motion of the rotary platform, and the walking motion of the whole machine.

2. What are the working features of the excavator bucket?
The working feature of the excavator bucket is forward travel. The bucket is forced to cut soil from the bottom to the top, the digging force is large, and the production efficiency is high. It is suitable for excavating the first to third types of soil with a moisture content of not more than 27%, and cooperates with the dump truck to complete the entire excavation and transportation operation. In addition, it can also excavate large dry foundation pits and mounds.

3. What is the difference between gradeability and lifting capacity of an excavator?
Gradeability refers to the ability to climb, descend, or stop on a firm, level slope. Lift capacity refers to the lesser of the rated stable lift capacity or the rated hydraulic lift capacity. The two are important elements that constitute the basic performance of the excavator, and are also important parameters affecting the performance of the excavator.

4. Common excavator attachments and their uses
Statistically, there are more than 20 kinds of excavator attachments, and the common ones are the following 7 kinds: breaker, hydraulic shear, vibratory ram, quick joint, ripper, and wood grabber. The breaker is mainly used for mining and demolition of concrete; the hydraulic shear is mainly used for the demolition of buildings; the vibratory ram is mainly used for water conservancy slope protection and the construction of high-speed and railway slopes; The rippers are mainly used for weathering stone construction; the wood grabber is for grabbing wood and bamboo. After a redesign, it can be used for grabbing stones and scrap steel.
