Specialist Excavator Modifications for Demanding Projects

First Square Equipment provides bespoke excavator modifications for tunnelling, shaft sinking, demolition and specialist construction projects. From slide cab conversions and counterweight systems to camera upgrades and underground safety packages, we design and build modifications to suit real site conditions and customer requirements.

Our engineering and workshop facilities specialise in bespoke excavator modifications for customers across the UK and worldwide. Every project is built around the machine, the application and the operator’s requirements. Whether you need improved visibility, greater stability, additional safety systems or a complete underground conversion, we can deliver a practical solution.

Excavator Modification Benefits

Why Modify Your Excavator?

Excavator modifications improve machine safety, operator visibility, underground performance and long-term reliability. Every conversion is designed around real working environments, helping customers maximise productivity and reduce downtime.

Slide Cab Conversions

Forward sliding cab systems improve operator visibility and access in tunnelling and shaft sinking applications, helping improve both safety and precision underground.

Counterweight Solutions

Additional counterweight systems improve excavator balance and stability, with underslung, rear overhang, top mounted and vertical slab options available.

Undercarriage Upgrades

Track frames can be widened for improved machine stability, while undercarriage modifications help prevent track loss and improve site performance.

Camera Systems

Wireless heavy-duty camera systems improve operator visibility around the machine, helping monitor the bucket, hazards and working areas more safely.

Control Systems

We work with leading control system providers to supply slew limiters, dig planning, load monitoring, geofencing and advanced machine safety systems.

Fire & Dust Suppression

Additional fire suppression and dust suppression systems help machines meet site requirements and improve safety in enclosed and underground environments.

Built Around Your Requirements

Every excavator conversion starts with understanding how the machine will be used. We work closely with customers to plan slide distances, floor visibility, counterweight requirements, protection systems and operating conditions to create the right solution for the job.

Engineered for Specialist Applications

From tunnelling and shaft sinking to demolition and deep excavation, our modifications are designed for demanding environments where standard factory machines are not enough. Our in-house engineering team ensures every conversion is practical, safe and built to last.

How We Work

Every excavator modification is designed, manufactured and tested to suit the customer’s machine, application and budget. From concept through to installation, we provide complete engineering support.

Customer Consultation

We begin by discussing the project requirements in detail, including working conditions, operator needs, safety priorities and machine limitations.

Supply Only

We can supply major conversion components for customer self-installation, complete with instructions and engineering support where required.

CAD Design

Our in-house designers convert initial ideas into full engineering drawings using the latest CAD software and practical construction site experience.

Supply & Fit

We also offer full turnkey installation in our UK workshops, with testing completed before the machine is returned ready for work.

Workshop Manufacture

Major components are manufactured in-house in our UK workshops using purpose-built fabrication facilities for strength, accuracy and reliability.

Worldwide Support

Our service engineers can travel worldwide to support installation, commissioning and specialist excavator conversions wherever required.
