Wheel Excavator for Sale in HAMAC
Wheel excavator is an excavator with high mobility, usually equipped with four large wheels, and is an excavating machine that relies on tires as walking parts. It can drive and turn on a relatively flat surface with fast walking speed without damaging the road surface and can travel far. The distance can be changed automatically, and various operating devices can be quickly replaced. It has the distinctive characteristics of maneuverability, flexibility and high efficiency. Wheel excavators can excavate and move materials in airports, ports, oil fields, mines, urban and rural construction, farmland water conservancy, and rapid repairs.
What Are Advantages of Wheel Excavators
Flexibility. Wheeled type excavators are generally more maneuverable than crawler excavators and are able to move quickly around construction sites. They are generally better suited for use in places that require frequent movement, such as cities and suburbs.
Drive fast. Wheeled excavators drive better on hard surfaces and get to construction sites faster.
Less damage to the ground. Compared with crawler excavators, the weight distribution of wheel excavators is more uniform. So when constructing on the construction site, the ground pressure of wheel excavators will be smaller and the damage to the ground will be relatively small.
Lower energy consumption. Especially when driving on hard roads. Therefore, wheeled excavators can save energy and operating costs more. Maintenance is simple. Since the structure of the wheeled excavator is relatively simple, maintenance is also easier.
Excellent Performance of Hydraulic Wheel Excavators
- The technical performance is improved, and the variety of working devices is expanded. Compared with the mechanical excavator of the same level, the single-bucket hydraulic excavator has approximately double the digging force.
- Easy to operate and more flexible. The manual hydraulic valve is used for easy operation. It can reduce labor intensity of the driver. In addition, the cab and the machine shed are completely separated, the noise is reduced, the vision is good, the vibration is reduced, and the working conditions of the driver are improved.
- The transmission performance is improved, and the work is stable, safe and reliable. After the hydraulic transmission is adopted, the speed can be adjusted steplessly and the speed adjustment range is large. A lower stable speed can be obtained, the movement inertia of the hydraulic components is small and it can be reversed at high speed.
- The structure is simplified, the wearing parts are reduced, and the overall weight is light. The hydraulic excavator of the same level can reduce the total weight by 30~40% compared with the mechanical excavator.
- Hydraulic components are easy to achieve standardization, serialization and generalization. It is convenient to organize specialized production, further improve product quality and reduce cost.
- The mechanism layout is reasonable and compact. Since the hydraulic components are connected by oil pipes, the mutual position of the various mechanism components is not limited by the influence of the transmission relationship. And the layout can be more flexible, reasonable and compact.
- Easy to automate. It is convenient to combine with electricity and pneumatic to form an automatic control and remote control system.

The Structure of Wheeled Excavator
The common excavator structure includes power unit, working device, slewing mechanism, steering mechanism, transmission mechanism, walking mechanism and auxiliary facilities. From the appearance, the excavator consists of three parts, the working device, the upper turntable, and the walking mechanism.
The working device is hinged to the front end of the slewing platform through pivot pins.
The slewing platform is connected with the lower mechanism through a slewing bearing.
The engine is placed on the slewing platform behind.
The cab is placed on the left front of the slewing platform.
The front end of the lower mechanism is equipped with a bulldozing blade.

The Differences Between Wheeled Type Excavator And Crawler Excavator
The structure is different. Wheeled excavators use four wheels to drive, while crawler excavators use crawlers to drive. Wheeled excavators are relatively light and easy to drive on relatively flat ground, while crawler excavators are more suitable for driving on uneven ground.
Travel speeds are different. Wheel excavators travel relatively fast, while crawler excavators travel slower. Wheeled excavators are easier and faster to move between construction sites. But when working, crawler excavators usually have better stability and balance. The scope of application is different. Wheeled excavators are suitable for foundation construction and earthwork operations on relatively flat roads and sites. The crawler excavator is suitable for mining, construction and complex terrain excavation operations.
The cost is different. In general, wheeled excavators are less expensive and easier to maintain than crawler excavators. But the working efficiency is low under unfavorable terrain conditions, while the crawler excavator has better operating performance and efficiency under difficult terrain conditions, but the cost is higher.
Wheel Excavator Operation Skills and Safety Precautions
Maintain a level and stable position. When loading, the body should be in a horizontal and stable position, otherwise it is difficult to accurately control the rotary unloading, thereby prolonging the operation cycle time.
Keep a proper distance. Keep a proper distance between the body and the truck to prevent the tail of the body from colliding with the truck when turning 180 degrees.
Control the rotation angle. Try to carry out left-turn loading as much as possible, so that the field of view is wide and the work efficiency is high. At the same time, it is necessary to correctly grasp the rotation angle to reduce the time for turning.
First load the sand and then place the large stones. When loading the car, first load the sand and then place the large stones, which can reduce the impact on the car.
Know how compact the soil is. When working in soft soil, you should understand the compactness of the soil, pay attention to limiting the digging range of the bucket, and prevent accidents such as landslides and landslides and deep settlement of the vehicle body.
Wheel Excavator Operation Skills and Safety Precautions
Strict quality control. Structural parts are produced independently, and the quality control of the whole process. The finite element analysis is carried out for the stressed parts, and all the key welds have been tested by non-destructive testing.
The performance of the equipment is stable, the vehicle body is durable, the operating room is enlarged, and the working environment is more humanized. The seat has a two-way adjustment function, which is suitable for both work and rest.
