TERMS OF REFERENCE FOR THE DESIGN

Compiled on the basis of GOST 15.001-88.

1. Name and scope of application.

Name: development of a working for washing road barriers based on KAMAZ-6520.

Field of application: cleaning of road barriers in the summer from dust, dirt, plaque, etc.

Brief description: an improved version of the frame and brush installed on KAMAZ – 6520.

2. Basis for development.

The need to modernize the equipment for washing road barriers in the summer from various kinds of pollution.

3.Purpose and purpose of development.

Increasing the working area of the brush and improving the frame, respectively, improving the functional qualities of the equipment for washing road barriers.

4.Sources of development.

G.L. Karaban. Machines for urban economy. M.: Mashinostroenie. 1988. 270 s.
I.P. Borodachev. Handbook of the designer of road machines. M.: Mashinostroenie. 1965. 724 s.

Assignment from the Department of IGS

5. Technical requirements.

The main purpose is the removal of various kinds of garbage on the road surface;

Type of control - with the help of levers, mechanical;

Drive type – hydraulic;

Tank capacity, l – 14000

Distribution width, m – up to 2,2

Interval of change in the width of distribution, m – 0,2

Specific rate of bottling, l/s - from 0.3 to 3

Maximum engine power, kW – 116

Weight without load, kg not more than – 10350

Number of hydraulic control cylinders, pcs – 2;

Basic Vehicle – KAMAZ 6520

Brush diameter – 1060.

6. Ergonomic performance

The control of technical devices installed on the base machine must be smooth, the operator's console must comply with modern interior standards, the handles of the remote control must be streamlined.

7.Security requirements

Hydraulic hoses and hoses must be sealed, adapters must be free from defects, the hydraulic system must be in good condition, the operator and personnel must work in a protective helmet and work suit.

8. Economic indicators

Payback of equipment for washing road barriers - about one year with standardized use for its intended purpose
