The best middle class bulldozer. The choice of professionals

A bulldozer is an earth-moving machine capable of moving independently and efficiently excavating soil or other rocks. The equipment has a simple configuration. The main part is a tractor or tractor, combining a powerful chassis and a cabin with controls. The working unit of the bulldozer is represented by a curved profile blade located outside the main structure. High productivity, the ability to move large volumes of rock and the ability to perform various types of tasks have ensured the demand for this equipment in many areas.

Areas of use

Today, bulldozers are actively used in road construction, construction, mining and other enterprises. The ability of equipment to cut, dig and move soil, rocks and other bulk materials is also used to mechanize such types of work as:

• leveling of territories and cleaning of gentle slopes;
• removal of fertile soil during construction site preparation;
• creation of shallow channels;
• arrangement of embankments;
• cleaning the bases for the foundations of structures;
• development of soil on slopes;
• filling trenches and other depressions;
• clearing the mining area;
• clearing large areas of debris, stones, snow, etc.

Information in tabular form

To make it easier to compare offers from different brands when choosing a bulldozer, it is recommended to create a table, an approximate view of which is given below. Everyone will be able to supplement it with information that they deem necessary.

In modern conditions of private ownership, business owners play a decisive role in the acquisition of equipment. Unfortunately, they often do not listen to the opinions of experts and follow the path of purchasing more budget machines, without studying all the consequences of purchasing cheap, but not always high-quality equipment.

Types of bulldozers

By appointment. This criterion determines the possibility of using bulldozers for certain types of work. The technique is:

• general purpose – designed for earthmoving, planning and construction tasks;
• specialized - such bulldozers are used in underground or underwater mining.

According to the type of climate control. This feature indicates the ability to operate machines in certain climatic zones. Bulldozers may have a non-standard design:

• with adaptation for work in low temperature conditions (up to -50 degrees);
• with adaptation to the tropical climate (temperatures up to +45 degrees and increased precipitation).

On the chassis. The type of chassis determines the ability to move equipment on different types of surfaces. A modern bulldozer may have the following movable base:

• tracked – effective for use in off-road conditions;

• wheeled – Suitable for frequent travel on public roads.

By dump type. The shield, the main working part of a bulldozer, can have different designs and mobility. Depending on the model, the equipment is equipped with the following types of dumps:

• non-rotating – installed perpendicularly and moves up/down;
• rotary – mounted at an angle in a horizontal or vertical plane;
• universal - consists of two halves, makes turns in different directions.

According to the lifting drive mechanism. This feature determines the maneuverability of the working body of the bulldozer (turning, lowering, skewing, tilting). The lifting mechanism can be:

• hydraulic – consists of hydraulic cylinders;
• electromechanical – has a combined configuration;
• mechanical - includes a winch and a system of rope blocks.
