National Tracked Dumper Hire: Leading the Way with Morooka MST-4000VDRs

Since its inception nearly nine years ago, National Tracked Dumper Hire Ltd (NTD) has become a dominant force in the UK’s construction and heavy equipment industry. Through continuous investment, NTD boasts one of the most extensive ranges of tracked dumpers available for hire across the UK.

Pioneering the UK Market with Modern Tracked Dumpers

NTD has been pivotal in reintroducing modern 360˚ rotating tracked dumpers to the UK market. Recently, NTD expanded its fleet with two new 25-tonne Morooka MST-4000VDRs, the largest in the manufacturer’s range and the first of their kind in the UK. These dumpers, capable of a 20,000kg payload, are unmatched in their class. Powered by a Stage V Caterpillar 9.3B engine producing 420HP, the MST-4000VDR offers exceptional performance on demanding job sites.

Exceptional Performance and Environmental Sensitivity

Equipped with 850mm wide rubber tracks, the MST-4000VDR exerts just 11.8 psi of ground pressure when fully loaded, minimizing environmental impact. For context, an average human exerts 16 psi. This low ground pressure allows the MST-4000VDR to perform effectively in challenging conditions without causing significant ground damage.

Cost-Effective and Efficient

One Morooka MST-4000VDR can replace two smaller dumpers, requiring only one operator, thus reducing fuel consumption, emissions, and transport costs. “These are the largest rotating tracked dumpers globally, and we are the first in the UK to offer this model,” says Jim Booth from NTD, which operates from six locations nationwide.

Advanced Safety Features

The Morooka MST-4000VDR comes with a high level of standard safety features, including a factory-fitted 360-degree camera system. NTD has further enhanced safety with HFR (Human Form Recognition) visibility aid systems, providing operators with an additional layer of safety through ‘third eye’ alerts. Moreover, conventional mirrors have been replaced with dual camera monitors, improving visibility and eliminating blind spots.

Partnership with Cautrac

These advanced Morooka dumpers were acquired from Cautrac, the exclusive importer and distributor for Morooka in the UK and Ireland. Over the years, Morooka has significantly improved operator comfort and visibility with ROPS cabins and joystick controls, enhancing the overall operating experience.

Field Testing on Major Projects

After a recent visit to the Morooka factory in Japan, NTD Directors Richard Maclean and Jim Booth, along with Cautrac’s Managing Director Craig Taylor, quickly saw the value in adding the MST-4000VDRs to their fleet. These dumpers were immediately deployed on Gloucestershire’s £460 million A417 ‘Missing Link’ upgrade, where they have proven their capability in demanding conditions.

Nigel Weaver, Kier Works Manager for the A417 scheme, highlights the dumpers’ benefits: “These dumpers have been a godsend. Their low ground pressure and 360-degree rotation make them ideal for confined sites and environmentally sensitive areas, significantly reducing site damage and reinstatement costs.”

Innovative Design and Efficiency

Powered by a Cat C9.3B Stage V engine, the MST-4000VDR features high-strength Bridgestone rubber tracks and a reinforced undercarriage for exceptional stability and durability. The ROPS/FOPS cab offers greater comfort and safety, with an electric control travel lever for intuitive operation. Eco mode and the “Auto Decel” function further enhance fuel efficiency and reduce emissions.

Morooka has also made daily maintenance easier with efficient inspection arrangements and a front grille with a large opening for accessibility.

Growing Fleet and Nationwide Support

Since 2015, NTD’s fleet has grown substantially. With over 50 units, including the new MST-4000VDRs, NTD provides the UK’s most comprehensive tracked dumper depot network and field service team, ensuring top-tier support for customers nationwide.
