DEFINITION
The condition of the project land is sometimes still land that must be prepared before the land begins to be processed. If there are still shrubs or trees on the land, land clearing can be done using a dozer. To remove the top layer of soil, a scraper can be used. As for the formation of the land surface so that it is flat, in addition to a dozer, a motor grader can also be used.
- material lifting equipment, Transportation of loose material with relatively long distances, heavy equipment used in the form of belts, trucks, and wagons. These tools require other tools to help load the material into them. In addition to these heavy equipment, cranes are included in the category of material transport equipment because this tool can transport material vertically and then move it horizontally, but at a relatively small distance.
- material transfer tool, Heavy equipment included in this category is heavy equipment that is not normally used as a means of transportation but is used to move materials from one heavy equipment to another. Loaders and dozers are material transfer tools.
- compactor, If an area is filled with landfill, it is necessary to compact the land. Compaction is also carried out for road construction, be it dirt roads or roads with flexible or rigid pavements. Heavy equipment included as compactors are tamping rollers, pneumatic-tired rollers, tandem rollers, and others.
- processing tools, This tool is used to change natural rocks and minerals into a desired shape and size. The results of this tool, for example, are graded rock, cement, concrete, and asphalt. Heavy equipment included in this category is a crusher. Tools that can mix the above materials are also categorized into material processing tools such as concrete batch plants and asphalt mixing plants. Crusher Concrate Batch Plant Asphalt Mixing Plant
- final placement tool, Heavy equipment is classified in this category because its function is to place the material in the specified place. In this place or location the material is spread evenly and compacted according to the specified specifications. Heavy equipment included in this category are concrete spreaders, asphalt pavers, motor graders, and compactors.
- Excavator, What is meant by digging equipment here is heavy equipment whose function is to dig soil, both downwards and sideways. The excavated soil is usually stockpiled around it, it can also be loaded into a dump truck to be transported to another place. This type of tool is also known as an excavator. Some of the heavy equipment used to dig soil and rock. Heavy equipment included in this category are front shovels, backhoes, draglines, and clamshells.
heavy equipment operational classification
Heavy equipment, in operation, can be moved from one place to another, both movable and immovable or static. Thus the classification of heavy equipment based on its movement can be divided as follows.
- tool with drive, The propulsion tool is part of the heavy equipment that translates the results of the machine into work. The shape of the propulsion device is a crawler or centipede wheel and rubber tires. While the belt is a driving tool on the conveyor belt.
- static tool, Heavy equipment included in this classification are tower cranes, batching plants for both concrete and asphalt, and crusher plants.
Selection and Determination of Construction Work Equipment
The selection of heavy equipment is carried out at the planning stage, where the type, number, capacity of heavy equipment are the determining factors. Not all types of heavy equipment can be used for every construction project, therefore the selection of the right heavy equipment is very necessary. If an error occurs in the selection of heavy equipment, there will be delays in implementation, project costs that swell, and results that are not in accordance with the plan. In the selection of heavy equipment, there are several factors that must be considered so that errors in equipment selection can be avoided.
- Functions to be performed Heavy equipment is grouped according to its function such as digging, transporting, leveling surfaces, and others. Thus, the selection of heavy equipment must really pay attention to what type of work will be carried out
- Machine capacity. The selection of heavy equipment is based on the total volume or weight of the material to be transported or worked. The capacity of the selected tool must be appropriate so that the work can be completed at the specified time.
- The mode of operation of the machine is selected based on the direction (horizontal or vertical) and the distance of movement, speed, frequency of movement, and others.
- Limitation of the method used. Restrictions that affect the selection of heavy equipment include traffic regulations, costs, and unloading. In addition, the construction method used by the data makes the selection of tools subject to change.
- Economy. In addition to investment costs or equipment rental costs, operating and maintenance costs are an important factor in the selection of heavy equipment.
- Types of Projects There are several types of projects that generally use heavy equipment. These projects include building projects, ports, roads, bridges, irrigation, forest clearing, dams, and so on.
- Project location. The location of the project is also another important thing to consider in the selection of heavy equipment. For example, a project site in the highlands requires different heavy equipment and vice versa.
- Soil type and bearing capacity The type of soil at the project site and the type of material to be worked on can affect the heavy equipment to be used. Soil can be solid, loose, hard, or soft
- Field conditions, conditions with difficult terrain and relatively good terrain are other factors that influence the selection of heavy equipment.
