crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against high temperature generated when models are operated at their maximum capacity
Helical Gears & Pinion Shafts These have involute profile teeth and so are constructed using high alloy case hardening steel.
Shafts Low speed shafts made from medium carbon metal that is duly temperature treated and finished to high precision tolerance by grinding procedure, thus preventing leakage of oil and entry of dirt.
Bearings Antifriction bearings used to make sure long service life along with 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 normal speeds, splash lubrication is provided. At places where splash lubrication isn’t effective, a built-in/separate mounted lubrication oil pump is used 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 may withstand overhung loads that occur due to 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 building features include:

Finding make use of in Cranes & Hoists, these can be offered in range between 2 HP to 100 HP according to the specific process requirements of the customers. Further, the superior Equipment tooth geometry style also allows generation of maximum efficiency which includes –

Sizes
Dimensions
These gearboxes also provide ease of servicing as well as rigid, robust and torsion resistant casing so as to ensure long service life standards. The housing is made from quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of high temperature generated when the models are operated at optimum capacity. Further, appropriate ribs are positioned under bearing seats for high power with walls of adequate thickness to withstand the majority of serious stresses faced during procedure. Additional, we also hold experience in providing housing in cast steel/fabricated steel complete if required.
