Let’s torque about dragline PT

In the mining industry, draglines are a key piece of excavation equipment that have largely maintained the same design and functionality since they were first invented in 1904 by John W. Page, owner of Page Engineering Company. Read More

Gearmotors designed to drive heavy loads

Bulk handling equipment such as feeders and conveyors are essential to mines and quarries; they enable the transfer of materials from one stage of the process to the next. However, the drives that power these conveying systems need to be robust and hard wearing enough to withstand the rigours of their application.

NTN EA surface technology extends the life expectancy of bearings

A standard bearing of identical type and size will have the L10 fatigue life of around double its equivalent manufactured 50 years ago, and this is reflected in the increased dynamic load ratings published by bearing makers. This is because contemporary rolling bearings produced by reputable manufacturers are made from clean alloy steels with applied processing technologies which result in a much lower incidence of premature surface contact fatigue.
