SYSTEM AND RESOURCES IN HEAVY MACHINERY

To understand what a system is, it can be broken down into three basic components:

Input = Input = Resources = Inputs = Factors
Output = Output = Result = Product

The input is the resources necessary to obtain the output; are the resources necessary to obtain products.

The process is the transformation of the input into output; the transformation of resources into products.

The output is the result of the transformation from input to output; it is the result of the transformation of resources into products; is the product obtained after transformation of the input through the process.

Example:

If you have a plate with potato a la huancaína ready to be consumed.

Is it the input or the output?

It is the output, it is the result.

What were the input ?

The ingredients: potato, evaporated milk, cheese, etc. The labor: the person who is going to prepare it The equipment: the blender, the kitchen, the furniture, etc.

Utensils: dishes, cutlery, etc.

Energy: electric energy, gas for the kitchen

Financing: the money to make the purchases The place: the kitchen, the house or an establishment, etc.

What were the processes ?

One for the preparation of the sauce to the huancaína; another for boiling the potato; etc.

APPLICATION EXERCISES N ° 3

PRODUCTIVITY AND PRODUCTIVITY CONTROL INDICATORS IN HEAVY MACHINERY

Achievement of objectives or goals.

The objective or goal is the end to which someone's actions or desires are directed. It is called objective itself when it is expressed in a general way; goal is called when it is expressed in a specific way, such as when it specifies moment, quantity, time, among others.

Examples:

  1. Marita and Gloria are the secretaries of a company. One day their boss asks them to write a letter, each one, inviting staff from another company to participate in a championship that they are going to organize.

After two moments, Marita and Gloria deliver the requested job to the boss. This makes the review and sees that everything is in accordance.

Were Marita and Gloria effective?

Yes, because they fulfilled the proposed objective.

  1. Students at a study center participate in a marathon. Only two of them reach the goal: Pedro and Rafael.

Were Pedro and Rafael effective? Yes, because they reached the proposed goal before the others.

And the others, what were they? They were ineffective because they did not reach the goal before the others.

  1. Braulio and Jerónimo are two friends who each have S /.1000 to be invested in any business that pays them profit at the end of the month. At the end of the month, each earns profits.

Were they effective? Yes, because they made profits, and that was the proposed objective.

  1. Dimenhydrate and Gravol are pills that are consumed to remove dizziness from drunkenness or any other type, to remove nausea or the desire to vomit, or to avoid snooze. If you take them properly they are effective.

For the dizziness of drunkenness one consumes it after consuming all the alcohol (in the sense of finishing continuing to drink). To get rid of nausea, he consumes it after drinking all the alcohol. To avoid the soroche one consumes it before the trip.

  • Optimization of the means or resources used to achieve an objective. Optimal refers to finding the best way to carry out an activity. Examples: (Based on the effectiveness examples, mentioned above).
  1. The secretaries, Marita and Gloria, were both effective because they handed over the letter and the boss agreed with both. But Marita delivered it in 5 minutes and Gloria in 10 minutes.

Who was more efficient?

Marita, because she delivered it in less time. The resource "time" was optimized.

  1. Pedro and Rafael were effective reaching the goal before everyone else. They both did it at the same time. But Pedro arrived tired, panting and almost like fainting; instead, Rafael arrived well planted, stopped, in very good shape.

Who was more efficient?

Rafael, because he optimized the energy resource or the physical resistance.

  1. The two friends, Braulio and Jerónimo, were effective. But Braulio won S /.1000 and Jerónimo S /.500. Braulio was more efficient, because he earned more; Optimized the investment resource or money invested. Dimenhydrate and Gravol are effective, but Gravol exerts immediate action while Dimenhydrate takes some time. Gravol is more efficient.

EFFECTIVENESS

  • It is the sum of effectiveness and efficiency. Effectiveness cannot be measured by making comparisons such as who is more effective ?, but efficiency can be measured as well as who was more efficient? All the previous examples show cases of effectiveness not However, there were those who were more efficient. There was no ineffectiveness or inefficiency. Effectiveness, according to DRAE, is the ability to achieve the desired or expected effect.

VOLUME MEASURES FOR CONTROLLING THE PRODUCTIVITY OF HEAVY MACHINERY

PHYSICAL MAGNITUDES

Any measurement consists of attributing a numerical value to some property of a body, such as length or area.

These properties, known under the name of physical quantities, can be quantified by comparison with a pattern or with the parts of a pattern.

This pattern is the unit of physical magnitude or quantity that, by convention, has the value 1.

PHYSICAL MAGNITUDES

They are represented by a symbol, which is usually a letter.

Examples of physical quantities are: mass (m), whose unit of measurement in the international system is kilogram (kg); the length (l), which is measured in meters (m); time, which is measured in seconds (s); the speed (v), which is measured in meters divided per second (m / s), etc.

HEAVY MACHINERY

The main quantities that define the earthmoving machinery and by which one model or another is selected for a given job are:

  • Operating weight: weight is the measure of the gravitational force acting on an object. It will be expressed in kilograms (kg).The motor power (HP): is the amount of work done per unit of time. At higher power, the machine will do more work in the same time or, what is the same, a machine with more power than another will need less time to do the same work.

HEAVY MACHINERY

The unit of power that defines the machine will be the kilowatt (kW) or the horsepower (CV). The relationship between the two is:

1 kilowatt (kW) = 1,359 horsepower (CV)

HEAVY MACHINERY

The bucket capacity: will be defined in cubic meters (m3):

1 cubic meter (m3) = 1,000 liters (l)

HEAVY MACHINERY

Other quantities that define the machine and can be found in any catalog are:

  • General dimensions of the machine, which will be expressed in meters (m). Length of the rocker, which will also be expressed in meters (m). Boom dimension, which in this case usually comes expressed in millimeters (mm).

1,000 millimeters (mm) = 1 meter (m)

Depending on the length of the rocker, other variables are defined, such as the maximum digging depth, the maximum reach at ground level, the maximum dumping height and the maximum reach height. All of them are measured in meters (m).

DECIMAL METRIC

In workshops where past machinery equipment is used, volume measurements are used, the unit of which can be m3 or cm3, although the latter is usually preferred.

DECIMAL METRIC

Note.-
The units of volume and capacity allow us to measure the space of the containers.

Volume is the amount of space a body takes up.

The cubic meter (m3) is the international unit of volume.

DECIMAL METRIC

A detailed way to carry out conversions without any mistake is to take into account: a) Equivalence

  1. b) Rule of three

The equivalences for the volume measurements of the decimal metric system are as follows:

EQUIVALENCES

INSTRUMENT MEASURES FOR CONTROLLING THE PRODUCTIVITY OF HEAVY MACHINERY

HOUR METER

A hourmeter is a device that records the number of hours that a motor or equipment, usually electrical or mechanical, has been running since the last time the device was initialized.

The hour meter is activated only when the machine is running, not turned off.

This device is used to control preventive maintenance interventions on equipment.

HOUR METER

EXAMPLE OF RECORDING HOUR METER FOR EQUIPMENT CONTROL

EQUIPMENT CONTROL HOUR METER / MONTHLY

ELEMENTS OF THE HOUR METER CALCULATION

For practical purposes, we will also call the hourmeter hour. Thus we have: a) INITIAL TIME (HI)

Hour marked by the hour meter when the motor or equipment stopped operating at the beginning of the work. b) END TIME (HF)

Hour marked by the hour meter when the engine or equipment stopped operating at the end of the work. c) TOTAL TIME (HT)

Number of hours worked by the engine or equipment during the daily workday. It is also called machine-hour performed on the day.

  1. Find the initial and final hour meter in a developed form from Monday to Saturday of a front loader that works 6.16 h in a common fill quarry, taking into account that on Wednesday it works 5.84 h more. The final hour meter for Monday is 767 h.
  1. Find the initial and final hour meter of a developed form Monday through Wednesday of a backhoe that works in a common fill quarry: 7.25 am on Monday, 7.75 am on Tuesday, 7.57 am on Wednesday; As a reference, the final hour meter for Monday is 586.17 h.

Indicate the hour meters of a B230 L excavator that works in a sand rock quarry for 2.50 hours, increasing its work from the second day by 1.67 hours each day until the tenth day. The initial reference hour meter for the first day is 779 h.

OPERATING COSTS IN HEAVY MACHINERY

FUEL

Peruvian legislation establishes the following for calculating the cost of fuel:

"FUELS

The quantity and price of the fuels consumed will vary with the power, location, type of work and type of machinery to be used. The most exact way to know the value of fuel consumption is to take the data directly from the site. Initial values ​​are used that are provided by the technical manuals of the equipment, which must be compared with the values ​​that are given in the development of the project, which will allow real values ​​of fuel consumption on site. ”

FUEL

A precise way to perform this calculation, based on experts in the use of heavy machinery equipment, is the use of the following formula:

Formula

0.5 lb x hp to brake x FC

7.2 lb / g

Where:

GPH = gallons per hour

Brake HP = hp + 15% hp = 1.15 hp

FC = load factor

FUEL

Note.-
What is the nominal hp and the hp at the brake?

A) nominal hp: It is the net power of the motor when the equipment is parked, without performing any work (minimum power or maximum power) and you only have to take into account the serial number and the model of the heavy machine.

B) hp to the brake: It is the power of the motor increased by 15%, when the equipment begins to carry out its work (maximum power or power with load).

In heavy machinery, you cannot draw power from the compactor rollers, you only draw force. Also: 1 kW = 1.34 hp

FUEL

EXAMPLE:

Calculate the fuel consumption of the Model 247 Off-Road Loader, which travels on rocky land.

SOLUTION: hp = 54 FC = 0.65

0.5 x 1.15 x 54 x 0.65
