Organization and operation of the fleet of construction vehicles

Comprehensive mechanization - a method of complete mechanization of the construction industry.

With a large number of operations, the use of machines is more productive (efficient).

The main indicators for assessing the mechanization of construction and installation work and the equipment of QS mechanization deadlines are:

a) indicator of the mechanization of work:

- the level of mechanization is kmeh = (Vmeh / V) * 100

- the level of complex mechanization kkmekh = (Vkmekh / Vmeh) * 100

b) indicators of mechanical equipment - characterize the equipment of construction and installation organizations with mechanization terms and are defined as an indicator of the mechanical structure of construction or mechanical labor:

MS = (See (t.rub.) / Sotst) * 100;

Cm - the book value of the means of mechanization;

Sots - the volume of construction and installation work carried out in-house.

Mc = Cm / np;

Cm - the book value of machines and mechanisms;

np - the average number of workers.

- Power supply:

ES = N0 / V;

N0 is the total power of the engines of construction machines;

V - the annual volume of construction and installation work in mln. Rubles, performed in-house.

This = N0 / n.

Organizational forms of operation of the park of construction vehicles

1. Construction machines are on the balance of SU, SMU. The maintenance and operation of machines is managed by the service of the chief mechanic of management. At the request of superintendents machines are displayed on the site. According to the number of used cars / hour, confirmed interchangeable reports and established accounting prices, the cost of machinery and mechanisms is included in the cost of construction of the respective facilities. ("-" many difficulties)

2. Construction machines and equipment are on the balance of specialized departments that perform certain types of construction and installation works on a subcontract basis in a mechanized way. Machines and crews in this case are part of the mechanized sections, and the performance of the planned tasks by the section entirely depends on their work. The cost of maintaining these or other machines entirely belongs to the cost of work performed by the site. The calculation between the contractor and such an organization is made, as with the other sub, when the whole object or part of the work is completed (according to interest).

This procedure stimulates the selection and use of rational technology, respect for them and intensive exploitation. This form is most effective, but its scope is limited to certain types of fully mechanized work in conditions where there are sufficient amounts of work for a long period.

Currently, the 3rd and 4th forms are replaced by leasing - specialization in leasing of the same type machines.

Leasing companies enable construction companies to make long-term use of construction equipment for the production of certain types of work, accompanying them with technical repair and maintenance services, which allows the construction company to get rid of the need to create or develop an operational base and have all construction vehicles in their fleet. works
