Valve hydraulic system arrangement.

Hydraulic drive of crane mechanisms is made according to open two-pump hydraulic circuit.

A feature of the crane hydraulic circuit is the use of an adjustable hydraulic motor for driving a cargo winch and the presence of a hydraulic drive for extending the supports beams. These features make it possible to use the crane more efficiently in construction, installation and loading and unloading operations in cramped conditions.

The use of a two-pump circuit and a hydraulic distributor with a special intermediate section in the hydraulic drive allows the following combination of working operations:

- lifting (lowering) of boom without load with rotation of turning part;

- lifting (lowering) of load with telescoping of boom sections;

- lifting (lowering) of boom with lifting (lowering) of cargo;

- boom lifting (lowering) with boom sections telescoping;

- rotation of the rotary part with lifting (lowering) of the load;

Two axial-piston pumps of type 210.26 and 210.10 are used as the working pressure source. A pump of lower capacity is used to drive hydraulic supports and lock the springs of the rear chassis trolley, as well as a group of working mechanisms: rotation of the rotating part; lifting (lowering) and telescoping boom sections.

A higher-capacity pump serves to drive the main winch. The manual pump is designed to bring the crane from the operating to the transport position, in case of failure of the main pumps drive.

The pump drive is designed to transmit torque from the chassis gear box to the crane unit pumps. The drive is carried out by means of a power take-off box mounted directly

together with the transmission of the car.

Controls of the main operations of the crane are located in the cockpit.

Installation of the crane on remote supports and control of the spring locking mechanism is performed from the panel.

Research part.

Task:

Analyze defects occurring on car cranes operating in the Kaluga region. Develop a system for classification and coding of car crane defects.

Detailed classification makes it possible to find the most common defects characteristic of each type of crane. And the analysis of the obtained results makes it possible to develop methods for preventing defects, for diagnosing the crane during its operation.

After the classification, the obtained defects are encoded. Defect coding facilitates the creation of an electronic data bank. The Data Bank allowed for the rational organization, compact storage and rapid use of a variety of information on all the faucets.
