The Hyundai HL780-9 is a 30-tonne wheel loader designed to anchor high-volume operations in large-scale quarries, industrial stockpiles, and bulk handling facilities. Built to manage substantial payloads with a standard 5.1 m³ bucket, this machine focuses on maintaining a steady rhythm in demanding environments where cycle speed and structural stability are essential.
By balancing a 3,700 mm wheelbase with precise weight distribution, it provides a grounded platform for high-reach loading and heavy carrying, ensuring that large volumes of material move efficiently without compromising machine balance or operator confidence.
Performance is driven by the Cummins QSM11 engine, delivering 257 kW of net power through a fully automatic transmission that adapts to changing resistance. To ensure consistent penetration into dense stockpiles, the drivetrain features a hydraulic front differential lock and a conventional rear differential, maintaining traction on loose or uneven surfaces.
This setup allows the loader to maintain momentum during the dig phase, reducing tyre slip and drivetrain strain. Operators can further refine performance using three engine modes—Power, Standard, and Economy—matching the machine’s output to the specific density of the material being handled to manage fuel consumption effectively.
The HL780-9 utilizes a load-sensing hydraulic system with a variable displacement piston pump, which directs power only when required. This reduces heat build-up and ensures that steering and loading functions remain responsive even under maximum load. The integrated load-weighing system allows operators to monitor bucket weights in real-time, ensuring every cycle is optimized for maximum productivity.
To maximize time on the job site, the machine features ground-level access to all primary service points—including filters and fluid sight gauges—complemented by wide-opening engine side panels that simplify routine inspections and technical servicing.
The HL780-9 is engineered as a functional workspace that supports high-volume productivity by focusing on ergonomics and streamlined maintenance:
