crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against high temperature 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 metal that is duly heat treated and finished to high precision tolerance by grinding process, thus avoiding leakage of oil and entry of dirt.
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 direction, operating in and functional check 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/individual mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling systems provided inside lower component of housing based on power to be transmitted and ambient heat.
Overhung Loads Bearings can 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
Some of the standard building features include:

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

These gearboxes provide ease of servicing along with rigid, robust and torsion resistant housing so as to crane duty helical gearbox ensure long provider life standards. The housing is made from quality close grained Grey Cast Iron that’s proportioned to ensure proper radiation of high temperature generated when the units are operated at maximum capacity. Further, suitable ribs are placed under bearing chairs for high power with walls of enough thickness to withstand the majority of serious stresses faced during procedure. Further, we also hold expertise in providing housing in cast steel/fabricated steel finish if required.
