Q & A
What is the primary purpose of excavators in the construction industry?
-Excavators are primarily used for excavation, but they also serve various other purposes such as heavy lifting, demolition, river dredging, cutting of trees, and more.
What is unique about the design of an excavator's arm and cabin?
-Excavators have a long arm with a digging bucket at the end and a cabin for the machine operator. The cabin can rotate up to 360 degrees, which enhances the ease of operation.
In what forms are excavators available for construction work?
-Excavators are available in both wheeled and tracked forms of vehicles, catering to different terrain and project requirements.
What is a backhoe and what does it consist of?
-A backhoe is a versatile piece of construction equipment with an arrangement provided on the backside of the vehicle. It features a digging bucket at the rear and a loading bucket at the front, suitable for excavating trenches and loading/unloading materials.
What is the main function of a dragline excavator in construction?
-A dragline excavator is used for larger depth excavations and consists of a long boom with a digging bucket suspended from the top using a cable. It is utilized for port construction, underwater excavations, sediment removal, and more.
How do bulldozers assist in soil excavation?
-Bulldozers are used to remove the topsoil layer up to a particular depth using a sharp-edged wide metal plate at the front, which can be lowered and raised using hydraulic pistons.
What is the role of motor graders in road construction?
-Motor graders, also known as graders, are used to level the soil surface. They contain a horizontal blade between the front and rear wheels, which is lowered into the ground while working, and are also used for removing snow or dirt from roads.
What is the purpose of tractor scrapers in earth-moving operations?
-Tractor scrapers are used to provide a flattened soil surface through scrapping. They consist of a wheeled tractor vehicle at the front and a scrapping arrangement at the rear, which collects excavated soil in a hopper for transportation to a dump yard.
What are trenchers used for and what types are available?
-Trenchers are used to excavate trenches for pipeline laying, cable laying, and drainage purposes. They are available in two types: chain trenchers, which have a digging chain around a fixed long arm, and wheel trenchers, which have a metal wheel with digging teeth for excavating hard soil layers.
What is the purpose of loaders in a construction site?
-Loaders are used to load materials such as excavated soil, demolition waste, or raw materials onto dump trucks or other transport vehicles. They have a large bucket at the front with a shorter moving arm and can be either tracked or wheeled.
How do tower cranes contribute to the construction of tall structures?
-Tower cranes are fixed cranes used for hoisting heavy materials like pre-stressed concrete blocks and steel trusses to required heights in tall structure construction. They consist of a mast, a jib, a counter jib with a counterweight, and an operator cabin for control.
What is the function of a paver in road construction?
-A paver, or asphalt paver, is used to lay pavement. It contains a feeding bucket for continuous asphalt loading by dump trucks and distributes the asphalt evenly on the road surface with slight compaction, requiring a roller for perfect compaction afterward.
What are compactors used for and what types are available?
-Compactors, or rollers, are used to compact materials or the earth's surface. Types include smooth wheel rollers for compacting shallow layers of soil or asphalt, sheepfoot rollers for deep compaction, and pneumatic tired rollers for compacting fine-grain soils and asphalt layers.
What is the role of telehandlers in construction?
-Telehandlers are hoisting equipment used to lift heavy materials to required heights or provide a construction platform for workers at greater heights. They have a long telescopic boom with attachments like forklifts, buckets, or cabin lifting jibs based on job requirements.
What is a feller buncher and how is it used in construction?
-A feller buncher is tree-cutting heavy equipment used to remove large trees in construction fields. It cuts the tree and gathers all the cut-down trees in one place, making it easier for loaders and dump trucks to handle.
What are dump trucks used for in construction sites?
-Dump trucks are used to carry materials in large quantities from one site to another or to the dump yard. Off-road dump trucks are commonly used in big construction sites, featuring large wheels and a huge space for materials, allowing them to operate in any ground conditions.
What is the purpose of pile boring equipment in construction?
-Pile boring equipment is used to make bore holes in the construction site for the installation of precast piles.
How is pile driving equipment used in construction?
-Pile driving equipment is used in pile foundation construction to lift the pile, hold it in the proper position, and drive it into the ground to the required depth, either hydraulically or by dropping.
