crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against warmth generated when products 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 steel that is duly heat treated and finished to high precision tolerance by grinding process, thus preventing leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life in addition to high process efficiency.
Path of rotation Though gearboxes are suitable for rotation in either direction, running in and functional test run is done toward rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At areas where splash lubrication is not effective, a built-in/separate mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling units provided inside lower part of housing depending on power to become transmitted and ambient temperature.
Overhung Loads Bearings can withstand overhung loads that arise because of mounting of flat and V-belt pulleys, equipment wheels and chain sprockets of suitable dimensions.
Painting Casting surfaces painted with linear epoxy primer (both internally and externally).

High load carrying capacity
Minimal noise generation
CONSTRUCTION FEATURES
Some 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 customers. Further, the superior Gear tooth geometry design also allows era of maximum efficiency that includes –

Sizes
Dimensions
These gearboxes provide ease of servicing along with rigid, robust and torsion resistant housing so as 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 warmth generated when the systems are operated at maximum capacity. Further, ideal ribs are positioned under bearing seats for high strength with walls of enough thickness to withstand most serious stresses faced during operation. Additional, we also hold knowledge in providing housing in cast steel/fabricated steel finish if required.
