Today, the scale of construction is increasing at an incredible speed. This speaks not only of the appearance of new buildings and structures, but also of the need for a large amount of building materials and equipment. Among the equipment used in this industry, the most popular is the wheeled excavator. With its help it is possible to carry out excavation work, as well as operations for unloading, loading and moving soil. Of course, a wheeled excavator is somewhat inferior to its caterpillar counterpart, but for work in urban conditions it will be indispensable. Because it does an excellent job of small earthmoving work and its wheels make it easy to move around the jobsite.

Wheel excavator structure

This earthmoving technique is made in the form of a frame, which has a pneumatic wheel running device. The turntable is also located here. The platform usually has the ability to make a full turn. Due to this feature of the turntable, the device will stand still, and the bucket will be able to rotate in any direction. For greater stability during loading, special outriggers are provided, which are called outriggers. Also, due to the presence of outriggers, the excavator will not slip while loading its bucket.

The weight of such excavators does not exceed 25 tons. Thanks to this, it can easily move in urban areas, while it will not harm the road surface. Also, unlike tracked models, this type of construction equipment can reach speeds of up to 30 km / h.

It should be noted that this technique can be supplemented with various suspended equipment. Then, if necessary, you can change its functionality, which will help significantly save money. But even with additional elements, it retains its original purpose and at the same time can be used in parallel as earth moving equipment.

Excavator types

First of all, this technique should be distinguished by its purpose and operating conditions. During construction, generic models are usually used. They are of medium size, quite productive, easily move from one object to another. For operation in mines, small models are used, this makes it possible to easily move in a confined space. There are also models for use in quarrying, these usually have a large bucket to increase the volume of excavated and submerged soil or rock.

The next parameter by which these earth-moving devices differ is the principle of operation. The most common option is the cyclical technique. Here the device has one bucket. The cycle consists of the following actions: loading, delivery to the place of unloading and subsequent unloading.After that, the cycle is repeated. There are also models with several buckets, here the principle of operation is continuous. The excavator has a rotor mechanism, with its help, several buckets rotate, thereby increasing work productivity.

Also, cyclic excavators, in turn, are divided into several groups, depending on the additional equipment. For work with soil that is above the prior art, models with a straight shovel are used. Such a shovel easily copes with any type of rock and efficiently copes with the task of loading and unloading. If it is necessary to carry out work where the soil is below the state of the art, models with a backhoe are used. Such models dig the soil in the direction of the excavator, they are mainly used for digging trenches or foundation pits. Working at great depths requires a model with great maneuverability. This is a dragline excavator, which is a device with a bucket placed on a rope that is suspended from the boom. For digging pits, underwater operation and loading, grab excavators are used. If the object is on an inclined surface, then models with telescopic equipment are used here. With their help, you can easily level the territory.

Also, this version of earthmoving equipment may differ in the type of engine used. There are two options here: diesel and electric excavators. Diesel engines have a fairly high fuel consumption, but this pays off in their agility, mobility and performance. Electrical options are used in cases where the technique does not need to move from object to object.

Principle of operation

This equipment is controlled from the cab by an operator who has special rights. The cab has a seat for the operator and a control panel. Since there is a lot of noise during the process, the cab is soundproofed. The control panel contains devices with the help of which there is control over the work process and safety. The wheeled excavator uses a hydraulic system, which makes it easy to operate.

So, the operator using the panel can perform the following operations:

  • Collect soil with a bucket;
  • Translate it to the required distance;
  • Unload the soil to the desired location.

It should also be borne in mind that this type of equipment can work both with the ground and with hard rocks. The equipment can be on the same level with the working platform, and above or below the platform.

Criterias of choice

First of all, before buying, you should decide on the purpose for which a wheeled excavator will be needed. If the purchase is made by an organization, then in this case, most likely, a wider range of requirements for the work will be presented. When buying a private person for employment, the range of work performed will be significantly narrowed.

Having decided on the goals that will be performed using this technique, you can move on to the size and power of the machine. The higher the weight of a given device, the more power it will have, but, therefore, the cost will also be higher. Keep in mind that a too bulky option will be inconvenient to work in urban areas. It doesn't matter whether it's a construction site or road work. Typically, these options are used in quarries. But too small a model may not cope with the tasks. Equally important is how far the extended boom can reach. If the working site is significantly different from the level of the equipment, then there is a risk that the bucket may not reach the required place. Usually this parameter is indicated in the device passport.

Also, do not forget to inquire about the engine power. Of course, the larger the machine, the higher the power will be. But still, among vehicles of the same size, choose the option with a more powerful engine.Thanks to this parameter, the speed and productivity of the services performed will be increased, and so it will be possible to take up work in difficult conditions.

Since most models run on diesel fuel, they therefore pollute the environment with exhaust gases. Make sure the option you select meets the regulations in your country or region.

Having decided on the technical characteristics, one should not forget about the convenience of using the equipment. Since the work performed can take more than one hour of time, the operator must have a comfortable seat. Control levers should be comfortable so that you do not have to apply a lot of force for each operation. The work performed can be quite noisy, for this the cabin must be sufficiently soundproofed.
