Crane Duty Helical Gearboxes

Crane Duty Gear Boxes are the type of gear system which is specifically designed and constructed for wide range of crane duty applications. Basically, for horizontal gear units helical gearbox is used and for vertical gear units spur gears are recommended.Helical gears are one type of cylindrical gears where the teeth are curved into a helix shape. Compared to spur gears (straight teeth), properly designed helical gears can have a larger total contact ratio which can improve vibration and noise. Badly designed helical gears can be noisier than well designed spur gears.
