Excavators for your construction project

The excavator is an important part of the construction process especially during the earlier periods of base laying in large construction projects. Like observed in an earlier article, the site conditions are very important when selecting the type of excavator to apply in a given project. The buckets of excavators can be changed, an aspect that makes them applicable in different ways including as hydraulic jack hammers and pile drivers. The excavator comes in varying sizes based on the length of the boom, bucket size, speed of operation, and length of arm. For each excavator, the production cycle can be used to gauge its performance. The production cycle is defined by the time taken by the excavator to fill the bucket with the load from the source, to swing, to dump, to return back to the source, and then to dig again. Thus, an increase in the operation speed would lead to an increase in the completion of a cycle. In most construction sites, excavators are used for digging soils and rocks, and for loading trucks used for dumping. It is important to know when to apply a given type of excavator in a construction project in order to ensure cost effectiveness, time saving, and efficiency of the excavator.Excavator1

Crawler Excavator

A crawler excavator is basically used for deep digging in the mining and construction industries. It is made of heavy material including iron or steel. The engine power in this type of excavator is high with the horse power strength ranging between 130 and 170 HP. The crawler excavator has a weight of between 40,000 and 60,000 pounds depending on the model or make. This type of excavator is the most efficient as it has an operating efficiency of 2000 rpm, a feature that allows them to dig up to 20 feet deep. Crawler excavators are mainly suited for sites that do not have linear landscapes, or those that the landscapes are rugged, requiring the escalator to climb steep terrains or move deep into the ground during excavation. Weather conditions may also affect excavator efficiency, especially during rainy seasons. Nevertheless, crawler excavators are efficient as compared to other excavators when working through rainy seasons as the chains have a better grip in the mud allowing them to navigate easily within a site of construction and complete the designated tasks without much delays. The chain-based locomotion system of these excavators allows them to move through any terrain without much difficulty, thus providing for increased efficiency in such conditions as compared to other excavators.

Wheeled Excavators

The only difference between this type of excavators and the crawler excavators is that this type of excavators move on wheels. The machines also weigh less as compared to the crawler excavators and have a lower horse power. This machines are best suited for sites that do not have rugged terrains as the wheels may make it difficult for them to navigate through some terrains and weathers such as rainy weathers. It is important to note that this type of excavators still provide for efficiency in applications that they are suited for and should not be deemed inefficient with a simple comparison to crawler excavators.

Long Reach Excavators

This can be either wheeled or crawler excavators, with a long arm than the rest of excavators used for other purposes in construction. This type of excavator is mainly applied in the destruction activities such as building demolition as it has the ability to reach the top of the building and to crumple the structures methodically.
