The difference between a conventional excavator and a zero swing excavator

Choosing an excavator that fits your project can be a daunting task with so many different types of excavators available in the market. The best way to make your choice more straightforward is to know what kind of excavation you need in your project. For example, an excavator suitable for bulk excavation may not be feasible for small excavation work during road repair. Different types of excavators require different skill sets to operate them effectively. So, let’s explore two of the most common configurations of excavators available in the market. This guide will help you in assessing your project requirements.

Zero Swing vs. Conventional Swing excavators

Zero swing and conventional swing excavators are two of the most common configurations available. These machines are available either to buy or rent from an excavator hire service. types are based on how the upper body of the excavator extends beyond the undercarriage width.

These excavators are different in terms of operation and their functioning.

Zero tail-swing excavator

Zero swing excavator hire machinery is very versatile and can do just as much work as a traditional or conventional swing excavator. In fact, in some scenarios, they outperform conventional swing excavators. Zero-turn excavators are a type where the upper body can rotate within the machine’s undercarriage width without extending beyond.  

Zero-turn excavators are very versatile and are ideal for residential projects that do not have as much space as larger projects. They can dig down to almost any level while being in tight spaces or corners. They are ideal for working close to buildings, fences, and other obstructions. When working to repair roads or highways, the operator can use them on one lane with minimal traffic disruption.

Due to reduced tail radius, zero swing excavators are likely to have lower-rated operating capacities than conventional swing designs. Plus, they are likely to pitch more than the traditional type when applied with heavy attachments or loads.

Now that you know the pros and cons of zero tail-swing excavators, you’re better able to pick one for your project. If you’re working in confined spaces where you may need to operate the machine through 90-degree corners, zero tail-swing is a good choice. Similarly, if you’re working for projects where pedestrian or traffic is a significant concern, choose a zero tail-swing excavator to avoid accidents or mishaps during operating time.

Conventional Tail-swing Excavators

Conventional tail-swing excavators have extended upper structures to achieve maximum digging performance and long-reach compared to reduced or zero tail-swing configurations.

As a result of the long tail swing radius, this machine offers excellent leverage factor that translates into higher outputs in dig depth and weight carrying capacities. Such a configuration allows for a more significant counterweight effect that provides the machine with greater leverage.

Conventional tail swing offers longer operating dimensions making them more productive and comfortable.

This type of excavator may not be feasible in confined spaces or areas where the machine is required to rotate through sharp corners or turns. So, if you’re looking to work in such sites, your ability will likely be restricted, and you may have to adjust the size accordingly to fit in the machine.

The bottom line

You have to assess your site conditions and the operating capacity you require for the job, depending on the deadlines and scope of work. A wrong decision during the planning stages may result in long-term detrimental impacts on your project performance and output.

You need to keep in mind the price and the budget you have agreed to. Compare the prices of both types of excavators and be sure to select a reliable seller and a reputable brand. It is recommended to obtain quotes from different dealers to assess the cost and make your decision accordingly.
