1.1. The place and role of course in the system of training

The discipline "Constructing Machines" is taught in accordance with the curriculum for bachelors specialty 192 "Civil Engineering".

Constructing Machines are an integral part of the system of machines that provide mechanization of work in civil engineering. Constructing machines facilitate and increase the productivity of workers and increase the efficiency of the operations in civil engineering. The course plays an important role in the formation of an engineer in civil engineering. It is directly related to production. The knowledge gained in the study of the discipline "Constructing Machines" students use in training-laboratory and practical classes, during all types of practices, and then as a specialist, constantly in their work and life.

1.2. The purpose and objectives of the course

The general purpose of the course is to teach students the basics of knowledge about hoisting, conveying, earthworks, concrete and manual machines.

The main purpose of the course - is the study of structures, calculation, design, rules of safe operation of hoisting, conveying, earthworks, concrete and manual machines. Tasks: to teach students to make the calculation schemes, to determine the stability and strength of parts, structures, as well as the structural shapes and sizes of the elements of hoisting, conveying, earthworks, concrete and manual machines.

1.3. Requirements for knowledge and skills acquired in the process of studying the course

As a result of studying the course, the student must know: purpose and classification of machines; classification of systems of machines by types of energy carrier; loads characteristics; productivity of machines; capacity of machines for bulk and piece cargoes; operating modes of mechanisms of hoisting, conveying, earthworks, concrete and manual machines.

As a result of studying the course, the student must be able: to determine the forces in the branches of the flexible traction element and the power of the drive; choose the location of the drive; to carry out the needed calculations for selections the elements of hoisting and conveying machines; to select the working attachment of the earthworks machines; to determine the needed capacity of the concrete machines; to select the the right type of manual machines and properly use them.

1.4. The list of courses, that provide the basis for the course study

The course is taught on the basis of knowledge of fundamental and professionally-oriented disciplines "Mathematics", "Descriptive geometry,"Engineering and computer graphics","Theoretical mechanics","Strength of materials ","Theory of machines and mechanisms","Machine parts".
