    Hägglunds Mellansel hydraulics lab: drive system insights for bulk mine handling

    Hägglunds Mellansel hydraulics lab: drive system insights for bulk mine handling

    First reported on International Mining – News

    30 Second Briefing

    Hägglunds, part of Bosch Rexroth, has opened a new hydraulics laboratory in Mellansel, Sweden to develop and test its hydraulic direct drive systems used on large apron feeders, bucketwheel reclaimers and conveyors. The lab focuses on integrated systems comprising a hydraulic motor, flexibly placed drive unit and dedicated control and monitoring system, allowing optimisation of torque control and start-up behaviour under high-load, low-speed conditions typical in bulk materials handling. For mine operators and designers, the facility should accelerate validation of drive configurations for retrofit and greenfield projects, particularly where variable-speed, stall-resistant drives are critical.

    Technical Brief

    • Laboratory test rigs are tailored to mining-scale applications such as large apron feeders and bucketwheel reclaimers.
    • Integrated control and monitoring hardware is installed to capture drive response under controlled load cases.
    • Physical separation of hydraulic motor and drive unit can be trialled to optimise layout around existing plant.
    • Test campaigns can reproduce low-speed, high-torque duty cycles typical of bulk materials handling equipment.

    Our Take

    Within the 897 Mining stories in our database, Sweden appears far less frequently than major mining hubs, so Hägglunds’ Mellansel hydraulics laboratory stands out as one of relatively few Nordic-based infrastructure items supporting global mine equipment supply chains.

    Hägglunds and Bosch Rexroth feature mainly in our ‘Product’ tag coverage as drive and hydraulics suppliers to large mills, conveyors and apron feeders, so an expanded test facility in Sweden likely underpins higher-torque, low-speed solutions for heavy-duty mining applications rather than mine-site construction per se.

    Among the 1,719 tag-matched ‘Projects’ and ‘Product’ pieces, most new labs and test centres are located close to major mining regions; siting this hydraulics laboratory in Mellansel suggests Bosch Rexroth is keeping R&D and high-end testing in a controlled European environment while serving equipment OEMs that export into harsher mining jurisdictions.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
