Features and benefits
Features and benefits


Compact, modular and mobile for underground spaces
Purpose‑built units designed to navigate tight drives and declines ensure safe, efficient explosive delivery in confined underground environments.


Suited to mechanised, automated and hands‑on mining
Flexible operating modes allow seamless integration with your existing fleet — from manual charging to fully mechanised and automated workflows.


Accurate loading across a wide range of densities
Precision control of energy and product density ensures consistent, repeatable charging that supports better blast outcomes and downstream productivity.


Rapid setup and relocation with multi‑hose capability
Fast deployment and the ability to charge multiple faces or headings enables higher utilisation and reduced downtime between blasts.


Proven safety performance underground
Decades of in‑mine application and robust safety systems help reduce manual handling, minimise exposure to hazards and maintain licence‑to‑operate standards.


Enhances productivity and reduces operational delays
Reliable, independent delivery systems keep development and production advancing, helping mines hit schedules while lowering rework and blasting costs.

Understanding Orica's underground delivery systems
What’s the difference between Orica’s Mobile Chargers and Modular Loaders? Mobile Chargers are self‑contained, highly mobile units designed to efficiently charge full rings or development drives. Modular Loaders are compact, transportable units set up at the face, ideal for sites where equipment uses ITs or where more flexible deployment is needed.
What applications are the Mobile Chargers suited for? Mobile Chargers, such as the MaxiCharger™, are ideal for underground development, production blasting, and civil construction applications. They excel where mechanisation and mobility improve productivity.
What is the Hypercharge total loading service?Hypercharge™ is Orica’s fully supported charging service that pairs advanced equipment like the MaxiCharger™ with specialist expertise, supply reliability and operational optimisation to deliver total loading efficiency.
Can the MaxiCharger™ deliver different emulsion densities? Yes. The MaxiCharger™ can deliver a range of densities and provides full control during charging to accurately match blast design requirements.
Who operates the Modular Loaders? Systems like the MaxiLoader™ are designed to be operated by your existing team, with Orica support as required.
When is the MiniLoader™ the best choice? The MiniLoader™ is ideal for modest-volume applications where a compact, flexible system is needed, such as development blasting and smaller-scale construction work.
What makes the BudLoader™ unique? The BudLoader™ is purpose‑built for shaft construction. Its circular shape and single lift point make hoisting fast and efficient, and its independently controlled multi‑hose system improves loading rates during shaft sinking or civil projects.
Can these systems be adapted for different carriers or site conditions? Yes. Loader units can be installed on a variety of mine carriers or customised for specialised operating environments.
