Our Suction Excavator machines enhance safety, significantly reducing the risk of incidents and injuries for excavation teams. They also contribute to a reduction in the number of on-site operators required, enabling safer spacing practices during work. Furthermore, these machines are instrumental in preventing service strikes, minimising potential damage to underground utilities and infrastructure.’


At Hercules, we use our FORS Silver Standard Suction Excavators for faster, safer and more efficient work processes. Our highly-skilled operatives use these excavators which are designed to reduce noise and disruption, maintaining a pleasant environment for both employees and the public. Our collection of 30 Suction Excavators can be used for a range of industrial projects, from water treatment to railways and increase productivity by ten times or more.


Hercules suction excavator operators are a testament to our unwavering commitment to safety and operational excellence. They are not just operators; they are highly skilled professionals who have undergone rigorous training to meet and exceed the highest industry standards. Equipped with in-depth knowledge of excavation techniques, our operators utilise our cutting-edge equipment with precision and care, ensuring that every task is executed with the utmost skill and efficiency. Our operator training programme is comprehensive, with a strong focus on Continual Professional Development, ensuring that they stay at the forefront of industry developments, safety protocols and best practice.

Efficient use of manpower

Suction Excavators are skillfully manoeuvred by a self-contained team comprising 1-2 highly trained operators. These individuals are highly trained to standards like CPCS–A78 and EUSR, making Herules operators the best around.

Less risk of project delays

Eliminating utility and cable strikes is of utmost importance. Suction Excavators are designed and proven to drastically reduce the risk of this happening, therefore minimising any potential injuries and also costs due to delays.

Cost effective

Suction Excavators are safer, quicker and a much more efficient use of resources than the utilisation of a workforce with multiple trades using traditional plant and equipment, which can be expensive and slow.

Protecting the environment

We choose Suction Excavators for cleaner, eco-friendly work sites, in line with Supply Chain Sustainability School commitments, adhering to purchasing standards and investing in top German technology.

Performance comparison

Here is how suction excavation measures up in varying soil types and against digging with hand tools. Suction excavation’s effectiveness can be assessed across a spectrum of soil conditions, making it a versatile solution for a wide range of excavation tasks.

    Our Clients


    “Firstly, thank you for arranging the Vac Ex yesterday at short notice, as I know this was a challenge logistically. I just wanted to let you know the vac ex & driver were absolutely superb! I have recently banned a provider from my sites due to inefficiency and your guy yesterday was a breath of fresh air. He arrived on site early and didn't ask "what time are we finishing", and the vac ex was still going strong after 4pm! The comment from site was "the driver made that boom dance". The Hercules Operator was very productive with difficult excavations. Happy to have the driver / Hercules back on my sites.
