Engineering machinery is machinery designed to perform engineering operations. Construction machinery is designed to perform construction operations. Certain construction machines perform a series of operations in sequence to achieve a final objective. Depending on their function, construction machinery can be classified into the following basic groups: excavating, roading, drilling, pile-driving, reinforcement, roofing, and finishing machinery, machinery for working with concrete, and machinery for carrying out preparatory work. Browse through this category for various engineering and construction machinery available in Zambian stores.
Dragline Excavator. Bulldozers. Graders. Wheel Tractor Scraper.
Different types of heavy equipment commonly used in the construction are as follows:
Excavators - Excavators are important and widely used equipment in construction industry. Their general purpose is to excavation but other than that they are also used for many purposes like heavy lifting, demolition, river dredging, cutting of trees etc.
Backhoe - Backhoe is another widely used equipment which is suitable for multiple purposes. The name itself telling that the hoe arrangement is provided on the back side of vehicle while loading bucket is provided in the front.
Dragline Excavator - Dragline excavator is another heavy equipment used in construction which is generally used for larger depth excavations. It consists a long length boom and digging bucket is suspended from the top of the boom using cable.
Bulldozers - Bulldozers are another type of soil excavating equipment which are used to remove the topsoil layer up to particular depth. The removal of soil is done by the sharp edged wide metal plate provided at its front
Graders - Graders also called as motor graders are another type of equipment used in construction especially for the construction of roads. It is mainly used to level the soil surface
Wheel Tractor Scraper - Wheel Tractor Scrapers are earth moving equipment used to provide flatten soil surface through scrapping. Front part contains wheeled tractor vehicle and rear part contain a scrapping arrangement such as horizontal front blade, conveyor belt and soil collecting hopper.
Trenchers - Trenchers or Trenching machines are used to excavate trenches in soil. These trenches are generally used for pipeline laying, cable laying, drainage purposes etc.
Loaders - Loaders are used in construction site to load the material onto dumpers, trucks etc. The materials may be excavated soil, demolition waste, raw materials, etc. A loader contain large sized bucket at its front with shorter moving arm.
Tower Cranes - Tower cranes are fixed cranes which are used for hoisting purposes in construction of tall structures. Heavy materials like pre-stressed concrete blocks, steel trusses, frames etc. can be easily lifted to required height using this type of equipment.
Pavers - Paver or Asphalt paver is pavement laying equipment which is used in road construction. Paver contains a feeding bucket in which asphalt is continuously loaded by the dump truck and paver distributes the asphalt evenly on the road
Compactors - Compactors or Rollers are used to compact the material or earth surface. Different types of compactors are available for different compacting purposes. Smooth wheel rollers are used for compacting shallow layers of soil or asphalt etc. sheep-foot rollers are used for deep compaction purposes.surface with slight compaction.
Telehandlers - Telehandlers are hoisting equipment used in construction to lift heavy materials up to required height or to provide construction platform for workers at greater heights etc. It contains a long telescopic boom which can be raised or lowered or forwarded.
