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 systems 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 heat 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 regular 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 units provided inside lower part of housing based on power to become transmitted and ambient temperature.
Overhung Loads Bearings may withstand overhung loads that arise 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 construction crane duty helical gearbox 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 era of maximum efficiency which includes –

Sizes
Dimensions
These gearboxes provide ease of servicing along with rigid, robust and torsion resistant housing so as to ensure long services life standards. The casing is constructed of quality close grained Grey Cast Iron that’s proportioned to make sure proper radiation of heat generated when the devices are operated at maximum capacity. Further, suitable ribs are positioned under bearing chairs for high strength with walls of enough thickness to withstand many severe stresses faced during operation. Additional, we also hold knowledge in providing casing in cast steel/fabricated steel complete if required.
