Front loaders
Despite the variety of front loaders on the market, most models use a standard hydraulic design. Such a system consists of a pump and a special tank for liquid, communicating through connecting lines. When the loader is operating, the oil in the hydraulic tank is supplied to the distribution valve. If the operator has activated the working equipment, a spool valve opens in the system, which is responsible for moving the corresponding mechanical unit. Oil begins to flow from the control valve into the corresponding hydraulic cylinder, driving the boom or bucket

Dozers
Work Equipment Control: Hydraulic systems control the raising, lowering and tilting of the bulldozer blade, allowing you to perform various jobs on the construction site. Raising and lowering the blade allows the bulldozer to collect or distribute materials on a construction site. This is especially useful when excavating, leveling surfaces or creating slopes. With hydraulic dozer control systems, the operator can efficiently perform a variety of jobsite tasks, improving productivity and job accuracy

Concrete mixers
The hydraulic system of the mixing drum consists of a planetary gearbox with a special support for the mixing drum, a variable displacement axial piston pump, a fixed displacement axial piston motor, a special oil cooler with tank and filter and an additional water pump. The hydraulic system operates in a closed loop like a hydrostatic transmission, and the pump and motor are typically of a swashplate design. With a hydrostatic transmission, the movement of the mixing drum is controlled by a single operator, resulting in smooth, stepless changes in speed and direction

Graders
Grader hydraulics are used to control the various parts and functions of this construction equipment. It allows you to raise and lower the blade (blade), adjust its angle and lateral displacement, control the frame and chassis of the grader, as well as perform other operations. Modern graders are usually equipped with high-tech hydraulic systems that provide precise and efficient control.

Horizontal drilling
Hydraulic systems provide control and control of both the rotation and angle of the drill string, giving the operator complete control of the drilling process. This innovative approach effectively overcomes soil resistance and ensures precise forward guidance of the drill pipe. The operator can easily adjust the inclination angle of the drill pipe in real time using the hydraulic system, which improves drilling accuracy and efficiency. Hydraulically controlled inclination angle reduces setup time and improves drilling productivity. Flexible inclination angle settings improve accuracy and maintain the desired drilling path. All this together creates optimal conditions for successful drilling with high accuracy and reliability. Hydraulic tilt control allows the operator to work more accurately and efficiently, minimizing risk and improving drilling performance.

Pile driving and drilling rigs
For piling rigs, hydraulics are used to transmit force and create enough pressure to force the hammer to strike the pile. Hydraulic systems can control the speed at which the pile sinks, adjust the impact force, and ensure precise positioning of the pile. This allows the installations to drive piles into the ground efficiently and accurately. In the case of drilling rigs, hydraulics also play an important role. It helps drive drilling equipment, control the rotation speed of the drilling rig, the feed of the drilling tool and the pressure on the bottom of the well. Hydraulic systems allow you to effectively drill holes in soil or rock of varying hardness. Thus, hydraulics significantly improve the performance and accuracy of piling and drilling rigs, making them more efficient and easier to use.

Concrete pumps
The hydraulic system plays a key role in transporting concrete to construction sites. It creates and maintains the high pressure required to move concrete through hoses and flanges. This allows the concrete to be distributed efficiently and evenly throughout the site. In addition, the hydraulic system controls the angles of rotation and inclination of the pump fittings. Thanks to this, the direction and distribution of concrete on the construction site can be precisely controlled, which is important for achieving the required accuracy and quality of construction work. The use of a hydraulic system in construction not only provides convenience and efficiency in the process of transporting concrete, but also increases the safety and accuracy of construction tasks.

Scrapers
Hydraulics in scrapers play an important role in various operations and ensure efficient operation of the machine. Here are some applications of hydraulics in scrapers: 1. **Raising and Lowering Bucket:** The hydraulic system allows you to control the raising and lowering of the scraper bucket to pick up and dump soil or materials. 2. **Blade Position Control:** Hydraulic cylinders are used to adjust the angle of the scraper blade, which helps in unloading soil onto the blade. 3. **Steering System Control:** The hydraulic system allows you to control the scraper's steering system for turning and maneuvering on the construction site. 4. **Speed Adjustment:** Hydraulic pumps and motors are used to adjust the speed of the scraper to ensure accurate and efficient operation. 5. **Cushioning:** The hydraulic system can be used to provide shock absorption and smooth out vibrations of the scraper when driving over uneven terrain. Thus, hydraulics play a key role in the functioning of scrapers, providing convenient control, efficient operation and reliability in a variety of construction applications.

Cold planer
The main function of hydraulics in a road milling machine is to control the various movements and actions of the machine. For example, a hydraulic system can be used to raise and lower the cutter to adjust the depth of cut. Hydraulics also control the speed of the cutter along the road, which allows you to precisely control the milling process. 👷♂️ The milling machine operator can control all these functions using special levers, valves and a control panel. The hydraulic system provides smooth and precise control of the machine, which is an important aspect for ensuring high quality pavement milling. 🛠️ Thus, hydraulics in a road milling machine significantly improves the productivity and efficiency of the machine, providing the operator with the necessary control over all processes during operation.
