What are the principles that should be followed in the selection of construction machinery?

1. Construction machinery and equipment can only be selected among the existing or possible mechanical equipment.

Although a certain kind of mechanical equipment may theoretically be beneficial to the shortening of the construction period and the saving of manpower, if it is not available, it cannot be used as an alternative.

2. The type of machinery and equipment should be considered from the construction conditions.

Construction conditions refer to the geology, topography, engineering quantity and construction progress of the construction site, especially the engineering quantity and construction progress, which is an important basis for the reasonable selection of machinery and equipment.

Generally speaking, in order to ensure the progress of construction and improve economic benefits.

The large amount of work should be advanced and high-efficiency large-scale machinery and equipment; If the engineering quantity is small, applicable small and medium-sized machinery and equipment should be used.

3. Whether the cost of loss and operation of fixed assets and operation cost should be considered.

4. It is necessary to consider the reasonable combination of various mechanical equipment.

On the one hand, it refers to the mutual adaptation of the main engine and auxiliary machinery and equipment in the number and production capacity; On the other hand, it refers to the combination of various mechanical equipment on the operation line.

5. It is necessary to consider the overall situation, not only considering this project, but also considering the use of machinery and equipment for other projects on the same site.

1) Select the machine according to the content of the operation;

2) select machinery according to the distance and road conditions;

3) select construction machinery according to soil quality;

4) select construction machinery according to meteorological conditions;

5) Select construction machinery according to the quantity of work.

It is economical and reasonable, and it can meet the needs of construction and production.

This depends on the method of nuclear concession of the Min Min.

It is common to have a series of tower cranes, mixers, material hoists, etc., as well as various construction vehicles.

18. The amount of things in your mind is related to your future future. If you want to master the eternal, then you must control the present.

Usage: Cost Performance, Repair & Spare Parts, Service.
