In mining, downtime is costly. Every hour lost impacts yield, productivity, and profitability. That’s why Prestolite Electric designs heavy-duty alternators and starter motors engineered to thrive in the harshest mining environments.
Standard-fit equipment often struggles once auxiliary loads are added, leading to premature failures. Prestolite solves this with high-output systems that deliver reliable performance well beyond OEM expectations.
The SRE275-24JB & PAD Mount 275A brushless alternators excel under extreme temperatures (-40°C to 125°C). Equipped with heat and dust-resistant seals, they provide isolated ground protection against stray voltage and remote-sense technology to extend battery life. Operators also benefit from superior charging at engine idle — essential for machines that spend long hours off duty cycle.
Equally impressive, is the M128R 12kW starter motor that combines soft-start technology with lightweight design (just 17.5kg vs competitors 50MT at 34kg). Built to last up to three times longer, it reduces ring gear wear and performs reliably in wet clutch applications.
Prestolite’s legacy spans more than a century, supplying 40+ OEMs worldwide including Caterpillar, Cummins, Komatsu, MTU, and Hitachi.
In Southern Africa, Shelhurst ComponentsPty Ltd is the master importer of Prestolite Electric and ensures ready access to this world-class range, keeping fleets moving and downtime to a minimum.
