Boston Gear Series 2000 Inline Drive for Mine Rope Shovel
An operator of a large open pit mine in the Western US needed a replacement drive
for the rope winch on one of its shovels. The winch, located inside the shovel’s housing,
is used to draw the heavy-duty cable (rope) from the drum and pull it through the boom
sheaves during routine rope replacement operations. The speed reducer is positioned
between the electric motor and winch drum.
To meet the challenging application requirements, Boston Gear recommended a
Series 2000 helical inline gear drive. The double reduction model has a NEMA
C-Face motor input with a 3-Jaw coupling. The rugged cast iron housing with
heavy-duty ground steel gears are designed to withstand adverse mine conditions.
Machined mounting registers allow for quick alignment so installation is fast and easy.
- High-ratio reductions
- Efficiency of 98% per gear
- Steel-hardened, ground
and polished helical gears
- Magnetic entrapment of
metallic wear debris
