Excavating Machinery For Various Applications

Moving earth is the only way to make room for construction, waste deposits, traffic, laying pipelines and other necessary infrastructure. The machineries used today are far more reliable, precise and fast compared to primitive tools used by our ancestors. We’ll be looking at what they are, how they function and why different machines are required for different jobs.

Dredge

A dredge is used in shallow waters, not on land. Aside from being a machine, it also refers to the operation or method of excavation. It removes underwater sediments and earth to keep waterways free for traffic.

Dredges are sometimes used to replenish sand on beaches, lost due to erosion. The drag bucket attached to the end scoops material from under water and transports it to a different location. The same machine is also used in fishing to search for clams and crabs in which case it’s known as a fishing dredge, the frame of which is covered with a chain mesh.

Backhoe loader

Backhoe loaders are used on land. They consist of two main mechanisms fitted to the front and rear, the loader and the backhoe. These machines are extremely versatile so much so that they’re often the only piece of heavy machinery used on construction sites. The loader, attached to the front, acts like a giant dustpan, scooping earth and other materials for transportation or to clear land. The backhoe on the rear is the actual excavator, capable of digging, lifting and moving materials with the help of an articulated arm or boom.

Despite being able to perform a range of jobs, backhoe loaders are relatively small. This makes them very useful for sites where space is at a premium and more than one job needs to be performed.

Trencher

For laying pipes and cables, trenchers are used to excavate the earth. They range in size from small portable models to large tracked machines. The digging mechanism is one of two types, a rockwheel or a digging chain. The first is a large toothed wheel effective for breaking up hard, compact earth or soft, loose dirt. It’s cheaper than a digging chain which is driven around a boom and is suitable for digging through very hard earth or to dig narrow trenches.

Excavator

Excavators are large heavy machines consisting of a bucket mounted on the end of a boom and a cab riding on tracks or wheels. The platform on which the cab sits rotates to provide more mobility and maneuverability. The boom and bucket resemble those found on backhoe loaders but the arm is usually longer and not articulated and if it is, generally moves only up and down.

Like backhoe loaders, excavators are very versatile and can perform a range of jobs. They may be used as trenchers, in demolition, heavy lifting, pile driving and, of course, excavating.

Skidder

Skidders are used in the logging industry to pull out cut trees for milling. Land is also cleared in the process either for construction or to make pathways. Two types of mechanisms are used in skidding, grapple buckets and cables. Machines with grapple buckets substitute winches to lift and transport timber while cable skidders use a winch to pull timber towards the skidder. It involves more work on the part of the operator and is more time-consuming. These factors have reduced their popularity in favor of grapple skidders.

From installing new pipelines, disposing off the wastes to laying groundwork for a new construction project, several earth moving machineries are used. For quality GTH earthmoving excavations, visit this site.
