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. The
bearings used in these gearboxes are friction free and have excellent
service life. Fitted with large oil reservoir, it is able to provide maximum
thermal efficiency.
Design
- The gear units are specifically designed for most of crane duty
related applications
- Horizontal gear units consist of helical gears while in vertical gear
units, the reduction is provided through spur gearing.
- All pinions are properly attached with the shafts. Materials required
for gears are usually forged from high grade alloy or carbon steel.
- Gears teeth are precisely cut with metric module system as per the
appropriate standard specifications.
- The housings are made up of cast iron and well machined with accurate
tolerance that guarantees perfect alignment of gears.
- Anti-friction bearings are fitted that ensure long service life and
excellent efficiency.
Features
- The rigid housing made up of grained cast iron helps to safely
transmit forces and loads
- Maximum thermal efficiency owing to large oil reservoir
- To ensure accurate tooth contact, parallel bearing bores are
maintained
- High tolerance
- High efficiency even when loaded to full capacity
- Precision gearing and accurate bearing alignment enables high
efficiency
- Precision gearing and accurate bearing alignment enables high
efficiency
- Precision gearing and accurate bearing alignment enables high
efficiency
- Anti-friction bearings helps to maintain high efficiency
- Positive seals avoid oil leakage during both high speed and low speed
