Suspended (Garland) Idlers
The introduction of bigger excavators and the resulting large lumps of material
caused, in earlier years, increased breakdowns of conveyors and rigid idler stations. The
reasons for the breakdowns were: bulky material, spillage, damage to belts (at impact
points). A reduction of the belt speed would have improved the situation, but would also
have forced a reduction in capacity. The search for an optimal solution brought about
steeper troughing angles and pushed development of the flexible roller base, known today
internationally under the name of the Garland system.
