Built for demanding, high-cycle environments, the Dieci DP7000 dumper is engineered to perform across a wide range of mining, tunnelling and infrastructure applications. Compact, powerful and highly manoeuvrable, it delivers serious payload capacity while remaining well suited to sites where space, access and terrain present ongoing challenges. 

With diesel vehicles accounting for 30% to 50% of greenhouse emissions at a mine site, replacing them with a battery-electric fleet is a sure way to drastically reduce overall CO₂ emissions, but how else can mines benefit from this technology?

Leading underground manufacturers Normet believe the answer lies with SmartDrive. This architecture for battery electric vehicles (BEV) was developed in collaboration with customers, building on feedback, predicting future trends, and assessing the limitations of diesel engines, and comes with a wealth of benefits for operators.

Dieci continues to invest in dumper truck design to meet the evolving requirements of modern worksites. Backed by more than 50 years of engineering experience, the focus has been on delivering machines that balance power, durability and operational efficiency. 

Designed with the same Italian engineering philosophy as Dieci’s telehandler range, Dieci dumpers offer robust construction, industry-standard components and straightforward maintenance. Lightweight yet strong, they are built to respond to the real conditions found on mining, tunnelling and construction sites, supporting efficient material movement while minimising downtime. 

The DP7000 is typical of Dieci’s compact, high-capacity dumper approach. With a much smaller footprint than conventional dump trucks and a tight turning circle unmatched in its class, it is particularly effective on sites where larger vehicles are difficult to deploy. 

Despite its compact size, the DP7000 delivers a maximum payload of 12,000 kg with heaped load volumes up to 7.5 cubic metres. Powered by a 93 kW (125 hp) FPT engine, the 6,800 kg machine provides strong torque and controlled performance, even in demanding off-road conditions. 

Measuring just 2,330 mm wide and 3,045 mm high, the DP7000 is well suited to restricted-access environments such as tunnel sites and confined mining operations. Built on the proven Dieci PX off-road chassis, it has demonstrated reliable performance in some of Australia’s harshest operating conditions, making it ideal for mining and industrial material handling.

Operator comfort and safety are integral to the DP7000’s design. The fully enclosed, ROPS–FOPS approved cab features powerful air conditioning, soundproofing and a wide double folding door for easy and safe access. 

A reversible driving seat with synchronized steering allows the operator to face either the cabin or the tray, delivering excellent visibility during loading and tipping operations. Large front and rear windows, work lights and near 360-degree visibility improve awareness in dusty or low-light conditions. 

With selectable steering modes and a compact chassis, the DP7000 is highly manoeuvrable in tight or complex worksites. Its agility, combined with substantial load capacity, helps reduce work cycles and boost overall site productivity. 

A range of localised custom options is available to meet site-specific compliance and operational requirements. The DP7000 can also be fitted with a self-loading shovel, enabling autonomous loading without the need for a support vehicle and further improving efficiency on remote or constrained sites.
