One of the main differences between the buildings of the modern world and the buildings that were built in the past is their strength against various incidents. This applies not only to buildings but to all types of human structures. Although various reasons affect this progress, without a doubt, one of the main reasons is the use of earthmoving machines and equipment.
The first step in the construction of buildings, roads, various facilities and all structures in general is excavation. Excavation itself is a specialized science that requires advanced machinery and equipment in addition to up-to-date knowledge. In fact, excavation is the preparation of the ground for the foundation of the structure.
✔️ Types of excavation machinery and equipment
The main purpose of excavation is to prepare a strong and at the same time completely flat ground that can bear the weight of the structure well and does not suffer from settlement. To achieve such a goal, engineers and experts use earthmoving machines and equipment.
Each of these equipments and machines are specially designed for specialized work, and using all of them together and for different parts of the project can produce the best and highest quality possible results. In the following, we will introduce some of the most famous earthmoving machines and equipment:
✔️ Bill and Mini Bill
Excavator is one of the necessary earthmoving equipment, which has different dimensions and sizes and is divided into two types: wheeled and chain. The wheeled type of excavator is designed to work on hard and solid ground and has a higher movement speed. In contrast to the chain type of excavator, it is designed to work on soft, loose and unstable ground. In fact, choosing the type of excavator depends on the dimensions of the land where the project is to be built.
Excavator performs two main tasks of digging and harvesting soil as well as loading in projects. This machine has the ability to rotate 360 degrees; This feature has made the excavator more efficient in projects with little working space. It is possible to install a hydraulic hammer (picor) to destroy and break hard surfaces on mechanical shovels and mini excavators.
Lower and mini loader
Immediately after the start of excavation operations, a large amount of soil, stone, sand (construction debris) accumulates at the project site, which must be thrown away or transferred to another place. Usually, this work is done by earthmoving machines and equipment that are special for carrying loads. Loaders and mini loaders are used to transport and transfer waste into transport vehicles. In fact, the loader is specially designed for this task and with the help of its large bucket, it can transfer a large amount of waste into the trucks.
It should be noted that the loaders also have two types of wheels and chains and they exist in different sizes. The wheeled type of loader is used for smooth and hard ground and the crawler type is used for loose and uneven ground.
✔️ Beck
Another earthmoving machine and equipment is Bekho. This machine, which is also known as "back shovel", is actually a multi-purpose machine that has wide applications in earthmoving operations. According to the type of operation of the backhoe, it is considered a very economical option.
The shovel in the back of this machine is responsible for digging and transferring various materials, and with the help of the loader in the front of this machine, you can perform unloading, loading and lifting of materials and waste.
✔️ Bulldozer
The most appropriate option in cases where a lot of force is needed to push different materials forward is a bulldozer. The bulldozer has a long and straight steel blade, whose height from the ground can be adjusted by the operator.
In addition to pushing materials, bulldozers can also be used to scrape and cut soft materials on the project surface. Considering that while cutting, it is also possible to move different materials by bulldozer, we can expect that the speed of work progress will be very high.
✔️ Roller
In the final stages of excavation and when the engineers have reached the final level of the project land, it is the turn of one of the most famous earthmoving machines and equipment. The compactor or roller, by compressing the soil surface and smoothing it at the same time, is one of the necessary equipments in earthmoving operations.
Rollers are also divided into different types. For example, smooth metal wheel rollers, goat leg rollers, and pneumatic rubber wheel rollers are the three main types of rollers that, depending on the type of ground, engineers decide which type of roller to use.
✔️ Grader
Another earthmoving machinery and equipment that is usually used in the final stages of the work is a grader. The grader is a powerful machine with a large size, which has an angled blade three to four meters long at its bottom. This blade can be fully adjusted by the operator in terms of angle, height and degree of placement.
The grader is specially designed for leveling and correcting the slope of different parts of the project by trimming the surface. It can also be used to mix sand and spread loose materials. One of the jobs in which you can always see the grader is road construction and excavation.
✔️ Script
If we were to somehow combine all the earthmoving machines and equipment we have mentioned so far and create a new machine, the result would definitely be a scraper. Scraper is a complete and perfect combination of loading and unloading machines.
This machine is one of the most cost-effective and efficient earthmoving machines and equipment that can simultaneously and automatically scrape the ground, drag materials, unload materials and spread them, and then reload them to carry the next load. It can be said that Scraper is an all-in-one machine that can have a great impact on the rapid progress of the project.
