Types of Heavy Machines for Site Excavation

Types of Heavy Machines for Site Excavation

Winning a construction contract is only the first step toward getting a piece of the profits in the sector nowadays. Several elements might go wrong and affect your profits even after delivering what you promised and adding a happy client to your portfolio. Among these are the machines you will use on your site. Some things in construction can be handled manually, and yet equipment hire costs might set you back a few thousand dollars.

The prudent choice for maximizing your profits might be buying secondhand diggers for sale, among other equipment, provided they are in optimal condition. While several dealers now sell used machines, get yours from a reputable provider so that you are sure the equipment is not stolen and the dealer is upfront on any issues the machine might have.

One crucial undertaking on construction sites is excavation. This is generally the first thing you will do to make the site ready for your project. To handle this task, the following are the heavy machines you can use.

Forward Loaders

These comprise a crawler tractor or tired pneumatic section at their front with a mounted wide bucket that moves in a vertical plane. Excavation using the forward loader is done by driving your machine forward with the bucket in the material you want to excavate. After this, the bucket us turned and lifted; therefore, holding and excavating your site. Loaders are often used for the excavation of material at a short distance below ground level.

Dragline Excavators

All excavators are, of course, meant for site excavation, but dragline excavators are the most popular. These are operated using cranes and similar machines with long booms. Excavation using a dragline excavator is achieved through pulling a bucket that is hanged on a cable towards the direction of your machine. Dragline excavators are suitable for the excavation of loose and soft materials at levels slightly above or beneath the machine’s tracks. They also suffice for underwater excavation.


These consist of a bucket attached to the tip of an articulated boom on a crawler tractor or tired pneumatic unit. The bucket arm, bucket, and boom are typically controlled using hydraulic rams. During excavation, the operator digs in an arc toward the machine from a small distance above its position before lifting and dumping the material into another vehicle or area. The maximum excavation depth of a backhoe is related to its boom’s length, though most machines have depth ranges of 2.6 to 6m.


These are tractors with front pusher blades that can be lowered and raised using hydraulic rams. Different blade attachments can be set at specific angles while moving the tractor section of the machine forward to excavate the site. Dozers can move excavated materials over a short distance, remove weak rocks, trim earthworks, and act as pushers for boosting the scraping power of other machines.

When investing in a machine, it is important to know the one that will deliver the highest returns for your construction. The machines discussed above are just some of the most versatile ones. They should be among your first options when considering the purchase of heavy equipment for your construction project or company.
