The construction industry has long relied on traditional manual methods for basic tasks such as digging trenches. While manual labor gets the job done, it is inefficient and poses risks to worker safety. A new machine called the Trencher is aiming to change all that by automating one of the most physically demanding parts of any construction project - digging trenches.
What is a Trencher?
A trencher is a piece of construction equipment designed to cut narrow trenches, usually for installing underground infrastructure such as pipes or cables. Trenchers come in many different varieties depending on their intended use, but they all work using the same basic principle. At its most basic level, a trencher consists of a cutting wheel or chain located at the front of the machine. As the machine moves forward, the cutting wheel digs into the ground, slicing a narrow trench. Augers inside the trench push loose dirt to the side so the trench remains clear for installation work.
Advantages of a Trencher Over Manual Labor
Safety
Manually digging trenches is backbreaking work that poses many safety hazards. Workers are exposed to risks such as falls, strained muscles, and injuries from hand tools. Trencher remove human workers from these dangerous situations. The machine does all the heavy lifting and dangerous cutting automatically from an enclosed cab, protecting the operator.
Speed and Efficiency
Trenchers can dig trenches significantly faster than humans with shovels. A single operator running a small walk-behind model can dig around 100 feet of trench per hour. Larger ride-on trenchers can cover 500 feet or more in an hour. This speed allows construction projects to stay on schedule. Fewer man hours are needed as well, cutting labor costs.
Consistency
Manually dug trenches often vary in depth, width and quality of cut. Trenchers ensure a precise and consistent trench is produced to required specifications every time. Precise trenches allow for smoother infrastructure installation work down the line.
Adaptable Designs for Any Job
Trenchers come in a wide range of sizes and configurations to suit any trenching application. Walk-behind models work well for residential jobs while large ride-on versions take on commercial and civil projects. Specialized versions allow trenching in hard soils and through roots or other obstacles. Operators simply choose the right tool for each unique digging challenge.
Types of Trenchers
Walk-Behind Trenchers
Small portable trenchers weighing 30-100 pounds that a single operator guides by hand. Ideal for digging utility lines in landscaped yards or tight spaces where larger machines won't fit. Produce trenches from 6-24 inches wide and 1-3 feet deep.
Ride-On Trenchers
Larger self-propelled machines that operators sit or stand behind to drive down a trench line. Weights range from 500 to over 10,000 pounds and power from diesel engines or hydraulics. Trench widths of 1-5 feet and depths of 3-8 feet. Often used for installing utility main lines.
Pipebursting/Rehabilitation Trenchers
Specialized trenchers used to break up old pipes in place during municipal pipe replacement projects. They allow for pipe replacement or insertion of new pipes without extensive digging. Reduces disruption to landscaping, traffic, and infrastructure.
The Future of Trenching
As construction demands increase to build infrastructure like pipelines, roadworks and communications networks, trenchers will become indispensable tools to help get projects completed efficiently. Their benefits of safety, speed and quality have made them a standard part of any serious contractor’s equipment lineup. Technology will also continue to develop trenchers. Advances like guidance systems, remote monitoring, and robotic features could automate trenching even further and take jobsites of the future to new frontiers of productivity and worker protection.
