Construction Equipments and their various usages



The site managers and construction planners should have clear ideas on the features of the leading construction equipments which are extensively utilized in various construction projects. The on-site productivity mainly depends on the amount of time needed and effort which can be significantly affected by the improper selection of type and size of construction equipments.


Excavation and Loading: One family of construction machines intended for excavation is generally categorized as a crane-shovel.


The crane-shovel consists of three most important components:


. A carrier or mounting which offers mobility and stability for the machine.
. A revolving deck or turntable which includes the power and control units.
. An attachment located forepart that provides the special functions in an operation.


The crawler mounting is specifically useful for crawling over comparatively rugged surfaces at a construction site. Other types of mounting range from truck mounting and wheel mounting offering superior mobility amid job sites, but superior surfaces are needed for functioning efficiently. The revolving deck contains a cab to accommodate the person responsible for operating the mounting and/or the revolving deck. Here in figure 2, the types of front end attachments might contain a crane with hook, claim shell, dragline, backhoe, shovel and piledriver.


Typical Machines in the Crane-Shovel Family: Here a tractor contains a crawler mounting and a non-revolving cab. If an earth moving blade is connected to the forepart of a tractor, the assembly is termed as a bulldozer. If a bucket is connected to its forepart, the assembly is called as a loader or bucket loader. There exist various types of loaders which caterer to most competently deal with materials containing diverse weights and moisture contents.

Scrapers refer to multiple-units of tractor-truck and blade-bucket groups with different combinations to allow the loading and hauling of earthwork. Most important types of scrapers consist of single engine two-axle or three axle scrapers, twin-engine all-wheel-drive scrapers, elevating scrapers, and push-pull scrapers. Every type contains dissimilar characteristics of rolling resistance, maneuverability stability, and speed in operation.
