crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against temperature generated when systems are operated in their maximum capacity
Helical Gears & Pinion Shafts These have involute profile teeth and are constructed using high alloy case hardening steel.
Shafts Low speed shafts made from medium carbon metal that is duly heat treated and finished to high precision tolerance by grinding process, thus stopping leakage of oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life along with high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either path, working in and functional test run is done in direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At places where splash lubrication is not effective, a built-in/separate mounted lubrication essential oil pump can be used for forced-feed lubrication.
Cooling Additional cooling products provided inside lower component of housing depending on power to become transmitted and ambient temperature.
Overhung Loads Bearings may withstand overhung loads that occur because of mounting of toned and V-belt pulleys, equipment wheels and chain sprockets of suitable dimensions.
Painting Casting areas painted with linear epoxy primer (both internally and externally).

High load carrying capacity
Minimal noise generation
CONSTRUCTION FEATURES
A few of the standard construction features include:

Finding make use of in Cranes & Hoists, these could be offered in range from 2 HP to 100 HP as per the specific process requirements of the customers. Further, the superior Gear tooth geometry design also allows generation of maximum efficiency which includes –

Sizes
Dimensions
These gearboxes provide ease of servicing and also rigid, robust and torsion resistant casing in order to ensure long service life standards. The housing is made of quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of high temperature generated when the products are operated at maximum capacity. Further, ideal ribs are placed under bearing seats for high power with walls of sufficient thickness to withstand most severe stresses faced during procedure. Further, we also hold knowledge in providing casing in cast steel/fabricated steel finish if required.
