crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against temperature generated when models are operated in their maximum capacity
Helical Gears & Pinion Shafts These possess involute profile teeth and are constructed using high alloy case hardening steel.
Shafts Low speed shafts created from medium carbon metal that is duly temperature treated and finished to high precision tolerance by grinding process, thus preventing leakage of essential oil and entry of dirt.
Bearings Antifriction bearings used to make sure long service life as well as high process efficiency.
Direction 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 locations where splash lubrication is not effective, a built-in/individual mounted lubrication essential oil pump is used for forced-feed lubrication.
Cooling Additional cooling devices provided inside lower component of housing depending on power to be transmitted and ambient heat.
Overhung Loads Bearings can withstand overhung loads that occur because of mounting of flat and V-belt pulleys, gear wheels and chain sprockets of appropriate 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 make use of in Cranes & Hoists, these can be offered in range from 2 HP to 100 HP according to the specific process needs of the clients. Further, the superior Equipment tooth geometry design also allows era of maximum efficiency that includes –

Sizes
Dimensions
These gearboxes provide ease of servicing as well as rigid, robust and torsion resistant casing so as to ensure long support life standards. The casing is made of quality close grained Grey Cast Iron that’s proportioned to ensure proper radiation of warmth generated when the devices are operated at optimum capacity. Further, suitable ribs are positioned under bearing seats for high power with walls of enough thickness to withstand many severe stresses faced during operation. Further, we also hold experience in providing casing in cast metal/fabricated steel complete if required.
