Advantages and disadvantages of belt excavator and wheel excavator

Advantages and disadvantages of belt excavator and wheel excavator:

1、 The wheeled excavator is easy to move. It is mainly used for small projects in cities. Do not work in a very soft place. The wheel type generally works on the cement ground and lawn without damaging the pavement track, which is a tool of the project and will crush the pavement. The use of wheeled excavator is not as extensive as that of crawler excavator. The use of wheeled excavator is affected by the environment and has certain limitations. It can only do a little work. Crawler excavator can basically adapt to any work and environment.

2、 Crawler excavator can not drive on the highway, but can work in muddy places without trapping. Its machinery is also large and its efficiency is higher than that of wheeled excavator. Crawler hydraulic excavators are different, but also related.

Crawler mechanism is widely used in construction machinery, tractors and other field vehicles. The traveling conditions are bad, so the traveling mechanism is required to have sufficient strength and stiffness, as well as good traveling and steering capacity. The track is in contact with the ground, and the drive wheel is not in contact with the ground.

When the motor drives the drive wheel to rotate, the drive wheel, under the action of the drive torque of the reducer, continuously rolls up the track from the rear through the meshing between the gear teeth on the drive wheel and the track chain. The grounded part of the track gives the ground a backward force, and the ground correspondingly gives the track a forward reaction force, which is the driving force to push the machine forward.

When the driving force is sufficient to overcome the travel resistance, the roller rolls forward on the upper surface of the track, thus driving the machine forward. The front and rear tracks of the crawler running mechanism of the whole machine can turn independently, so that the turning radius is smaller.

The crawler traveling device is composed of four wheels (driving wheel, roller, guide wheel, towing wheel and crawler), tensioning device, buffer spring and traveling mechanism

The relationship is:

1. Crawler type hydraulic excavator includes backhoe crawler type hydraulic excavator and front shovel crawler type hydraulic excavator;

2. Backhoe excavator includes backhoe crawler hydraulic excavator and backhoe wheel excavator.

In the construction of the project, there is no need to use the wheels of the wheel excavator, and there is a special transport vehicle. If you are walking on the site, to be honest, the crawler excavator is better for Xiaobian.

The advantages of crawler excavator mainly focus on the undercarriage parts:

Advantages.

Disadvantages: Relatively speaking, the investment is larger than that of wheel type. In addition, the mobility is not good. The maximum design speed is only 5-7KM/H, and the long-distance movement depends on the truck. Wheel excavator: advantages: small investment, fast action speed, generally 40-50KM/h.

Disadvantages: The scope of use is narrow, and most of them are road administration or municipal projects. They cannot enter mines or muddy areas, and their climbing ability is poor. Therefore, most excavator customers now choose crawler based excavator.
