Dump truck and its productivity count

Yesterday we have known and calculated the productivity capacity of excavator per hour (you can read it here), then today I will continue the calculation of dump truck production capacity per hour. Given the usual excavation work, soil or material will be poured into the dump truck for disposal in certain areas.
For example, at a trench excavation job in the middle of the city, the rest of the excavation should not be left in the work area, so it should be discarded. Similarly, at the location of the land that will be placed on a particular area, you must surely calculate how many m3 of soil dump that you can produce per hour by using several units of a dump truck so you can save time and cost.
If you do not have calculations on the production capacity of dump trucks per hour then you will find excavators/wheel loaders who have to stop working because there is no dump truck to be filled, or it could be a dump truck stalled due to lack of excavator production capacity. You have made the job incur losses
, where you have to pay per hour of labor and not offset the production capacity
In construction work, any detailed calculation will determine whether the job is successful or not, since almost all of this work is related to time, the sooner the job is done, the more likely you are to profit.
Should we know more closely about the dump truck, hopefully useful.

Previously a dump truck was a drag wagon pulled by a horse, had an open-box bed and a hinge. This exhaust system originally worked because of the force of gravity and still very manual, the technique is very simple, that directly drop the tub down then the cargo will also fall out too.
In the 19th century, dump trucks were thought to have handled agricultural sectors in western Europe but still used manual technical, then continued to develop until World War I, until finally, the dump truck evolved as we know it today, using hydraulic and steam engines.[source]
A type of truck that can be modified as a dump truck is very famous and once triumphed in Aceh is Toyota DA or better known as Toyota crocodile, this type of vehicle entered Indonesia in the 1960s and can still be found until now in several oil and gas mining companies in Aceh.
Currently, the dump truck is growing, in accordance with technological developments and needs. Not infrequently almost every area has a special workshop to create a dump truck that allows us to choose a quality dump truck and as needed.

The working order of dump trucks on construction works is.
- Dump trucks loaded into base camp using wheel loader or excavator.
- Dump trucks transporting material to the work site and materials in a ramp with graders.
- Dump trucks back to base camp to fill material back.
How to calculate the production capacity of a dump truck?
As an example, we will calculate the dump truck's productivity capacity per hour using a dump truck with a capacity of 3.5 tons, and 8.25 km distance from the base camp, so what is the production capacity of dump trucks per hour?
ANSWER
| Information | Code | Coefficient | Unit |
|---|---|---|---|
| Mileage | L | 8.25 | Km |
| Solid Content Weight | Bip | 1.81 | - |
| Weight of material volume | Bil | 1.51 | ton/m3 |
| Production Capacity/Hours (Wheel loader / excavator) | Q1 | 141.10 | m3 |
| Capacity Bak dump truck | V | 3.50 | tons |
| Efficiency factor | Fa | 0.83 | - |
| Average speed with payload | v1 | 40.00 | km/hour |
| Average velocity is uncharged | v2 | 50.00 | km/hour |
| Cycle time | - | - | - |
| - Material filling time = (V x 60) / (Q1 x Bil) | T1 | 0.99 | Minute |
| - Payload travel time is = (L : v1) x60 minutes | T2 | 12.38 | Minute |
| - Unconditional travel time = (L : v2) x60 minutes | 9.90 | Minute | |
| - Others (pouring material, etc.) | T4 | 2.00 | Minute |
| Total cycle time | Ts2 | 25.26 | minute |
| Production Capacity/hour (Dump truck) = (V x Fa x 60) / (Ts2 x Bip) | Q2 | 3.81 | m3 |
So according to the count can be assumed dump truck productivity with a capacity of a 3.5-ton tub and 8.25 km distance is 3.81 m3/hour.
Productivity capacity is also strongly affected by field conditions, material density, material availability, base camp distance to work site, dump truck conditions and other external factors. By knowing the production capacity of dump trucks per hour then you can calculate the units needed to complete your work.
The dump truck is a vehicle with an open-box bed that can transport material, a modern dump truck using hydraulics to lift the open-box bed for material to fall so it does not require additional power to pour the material.
By calculating the production capacity of dump trucks per hour, then you can save time and cost so that your construction work can be completed on time.
Dump trucks have long been used by humans to facilitate construction work, such as transporting materials at work sites or others.
This calculation is only an example and can be used by anyone, this calculation is in accordance with a technical analysis and can be developed in accordance with the needs of a field.
This is the only thing I can write on this occasion, over all the mistakes and lack of unintentional writing as a servant of God, I apologize.

Complete writings. Very giving information!
thank you
Very useful information about Dump truck and its productivity count thanks @kharrazi
Hopefully useful for us, thanks for stopping @bangjuh
Dump Truck is the initial capital of transportation, its very efficient means of transportation for work. the more of unit or bigger capacity of the cargo it can speed up a development of infrastructure.
nice post @kharrazi, im so interest for your post. steem on..
thanks for your time
steem on :)
