Many of the gear drives used in Forestry absorb punishment from changing speeds and high shock loads.  Heavy log weights dropped onto conveyors and other applications can snap the teeth of many gear drives. 

Proven through decades of service in forestry, Sumitomo Drive Technologies delivers the toughest gear drives available to meet the harsh demands of these applications.

"We chose Sumitomo for their high reduction efficiencies which makes them space conservative and fewer sizes and ratios satisfy the requirements we had – which saved money and reduced spares. That’s why we specify them and have over 400 Cyclo® speed reducers installed."
