Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against high temperature generated when units are operated in their maximum capacity
Helical Gears & Pinion Shafts These possess involute profile teeth and so are constructed using high alloy case hardening steel.
Shafts Low speed shafts created from medium carbon steel that is duly warmth treated and finished to high precision tolerance by grinding process, thus avoiding leakage of oil and entry of dust.
Bearings Antifriction bearings used to ensure long service life as well as high process efficiency.
Path of rotation Though gearboxes are suitable for rotation in either path, running in and functional test run is done in crane duty helical gearbox direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At areas where splash lubrication is not effective, a built-in/individual mounted lubrication essential oil pump is used for forced-feed lubrication.
Cooling Additional cooling models provided inside lower 
component of housing depending on power to be transmitted and ambient temp.
Overhung Loads Bearings may withstand overhung loads that arise due to mounting of flat and V-belt pulleys, equipment wheels and chain sprockets of appropriate 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 structure features include:
Finding use in Cranes & Hoists, these could be offered in range between 2 HP to 100 HP according to the specific process requirements of the clients. Further, the superior Equipment tooth geometry design also allows generation of maximum efficiency that includes –
Sizes
Dimensions
These gearboxes provide ease of servicing as well as rigid, robust and torsion resistant housing so as to ensure long provider life standards. The casing is made from quality close grained Grey Cast Iron that’s proportioned to make sure proper radiation of temperature generated when the systems are operated at optimum capacity. Further, appropriate ribs are positioned under bearing seats for high strength with walls of enough thickness to withstand many severe stresses faced during procedure. Further, we also hold knowledge in providing housing in cast metal/fabricated steel finish if required.
