Idlers, rollers and pulleys for high-tension overland conveyors and high-impact loading zones, in continuous operation on mines worldwide.
Years of Engineering
Longest Single Flight Supplied
Idlers, rollers and pulleys designed, manufactured and tested in-house. Optional Sensor Seal condition monitoring sits inside the roller.
Frames and rollers that support the belt at every width and loading. Low-friction 4-stage sealing. CEMA B–G and higher load ratings.
Drive, take-up, tail and bend pulleys that carry full belt tension, each verified by FEA against its actual load case.
A self-powered sensor built into the end seal of a Lorbrand roller, reading temperature, vibration and speed so a failing roller is found before it damages the belt.
Every component follows the same path from drawing to dispatch, whatever the product.
Geometry and materials worked up from your conveyor's load data, with finite element analysis on every pulley design.
Fabrication, machining and certified welding kept in-house, so tolerances are controlled by the people who set them.
TIR and running-torque testing on rollers; magnetic particle, ultrasonic and radiographic inspection of pulley welds, and static balancing of every pulley, dynamic where required.
Corrosion protection, export packaging and secure load restraint, with full inspection records for every pulley.
Lorbrand components run on conveyors in 40+ countries, supported by manufacturing in South Africa and Chile and a network of agents and distributors.
A continuous presence on some of the world's most demanding conveyors, from Radomiro Tomic in 1995 to Cerro Verde in 2025.
2025 · Nzérékoré, Guinea
Rio Tinto / Chalco
Almost 15,000 Lorbrand conveyor idlers carry ore at SimFer's Simandou iron ore mine in Guinea, part of Africa's largest greenfield mine-rail-port project.

2025 · Arequipa, Peru
Freeport-McMoRan
Freeport-McMoRan brought Lorbrand back to Cerro Verde for the 2025 IPCC expansion, thirty years after the first roller supply, with idlers and pulleys for conveyors that take over part of the pit's diesel truck haulage.

2025 · Antofagasta, Chile
Antofagasta Minerals
Belt feeders for Centinela's new 95,000 t/d concentrator left South Africa fully assembled and test-run, with Lorbrand idlers and pulleys already fitted, and travelled to Chile as abnormal loads.

2020 · Pilbara, Australia
Rio Tinto Iron Ore
Rio Tinto chose a 13 km overland conveyor over truck haulage at Western Turner Syncline 2 in the Pilbara, cutting mine-gate greenhouse gas by about 3.5%, with Lorbrand carry idler frames and rollers.

2016 · Antofagasta, Chile
Codelco
Codelco's Chuquicamata underground mine carries its ore out on three 11,000 t/h principal conveyors, widely called the world's most powerful conveyor installation, running on Lorbrand idlers.

2015 · Secunda, South Africa
Sasol Mining
Sasol's 26.8 km Impumelelo conveyor at Secunda, the world's longest single-flight conventional belt conveyor and still the record holder, runs on Lorbrand idlers and pulleys.

2008 · Northern Cape, South Africa
Assmang Limited
More than 90,000 Lorbrand rollers keep Assmang's greenfield Khumani iron ore mine moving, across a conveyor-intensive 10 Mt/y flowsheet in the Northern Cape.

1999 · Colorado, USA
Climax Molybdenum
Independent testing won Lorbrand exclusive idler supply for Henderson's 24 km three-flight overland conveyor, one of the most geometrically complex ever built, running through the old rail tunnels under the Continental Divide.

1998 · Sumbawa, Indonesia
Amman Mineral (formerly Newmont)
Nearly three decades after commissioning, many of the original 1998 Lorbrand idler rollers still turn on Batu Hijau's 6.8 km overland ore conveyor in Sumbawa, Indonesia.

1995 · Calama, Antofagasta Region, Chile
Codelco, División Radomiro Tomic
Lorbrand's first major Chilean reference: since 1995, its idlers and overland tables have carried 17 km of overland conveyors at Codelco's Radomiro Tomic copper mine, 3,000 m up in the Atacama.
