Product Description

Industry standard heavy duty diggers for hire

The best plant equipment on the market available to you.

Our 21T CAT 320F tracked diggers / excavators for hire are heavy duty, industrial pieces of plant equipment. They have been designed to provide powerful, efficient, fuel effective performance for a range of industrial excavation applications.

Tough and robust design

Capable of performing in harsh site environments

These CAT 320F 21T diggers / excavators are built to the highest standards, using robust and reliable materials and components. Featuring tough upper mainframes, lower frames and track-roller frames, with robotically welded booms, these diggers have been manufactured for maximum strength and durability. Greased track chains reduce friction between pins and bushings to significantly increase undercarriage life and protect from harsh site conditions, whilst reducing track noise when travelling. These CAT diggers also have high-pressure fuel pumps and fuel injectors which contribute to their overall durability and reliability. The robust, heavy duty design of these 21 tonne tracked diggers / excavators gives them the capability to carry out a range of large excavation jobs on site - including digging foundations and trenches, installing underground utilities, and moving huge amounts of sand, earth, debris and other materials.

Attachments to suit your job

Dig, dump, demolish and more.

We have a range of different digger / excavator accessories available for hire alongside our 21 tonne tracked diggers. These accessories allow you to complete a number of different jobs on site with the excavator. We can supply buckets with teeth for digging and excavating land, as well as buckets with flat blade edges, for scooping and dumping material. We also have demolition peckers available, which can be used for breaking up concrete, brick and tarmac. Simply speak to our hire team via telephone or online live chat about your individual requirements and we will be able to supply you with the buckets and other excavator attachments that you need.

From 1st April 2022, our suppliers will only fuel machines with white diesel. This is due to new government guidelines.

If you, as the hirer, refuel any equipment while it is in your possession, it must be with WHITE DIESEL.


If you return a machine refuelled with rebated diesel, suppliers will have to remove and dispose of the fuel. They must also flush the tank and supply lines before they can refuel them. The process is chargeable, with no exceptions.
