crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against temperature generated when products are operated at their maximum capacity
Helical Gears & Pinion Shafts These possess 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 avoiding leakage of essential oil and entry of dirt.
Bearings Antifriction bearings used to ensure long service life along with high process efficiency.
Direction of rotation Though gearboxes are ideal for rotation in either direction, working in and functional check run is done in direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At places where splash lubrication isn’t effective, a built-in/individual mounted lubrication essential oil pump can be used for forced-feed lubrication.
Cooling Additional cooling products provided inside lower component of housing depending on power to become transmitted and ambient temperature.
Overhung Loads Bearings may withstand overhung loads that arise because of mounting of toned and V-belt pulleys, equipment wheels and chain sprockets of suitable dimensions.
Painting Casting surfaces crane duty helical gearbox painted with linear epoxy primer (both internally and externally).

High load carrying capacity
Minimal noise generation
Some of the standard building features include:

Finding use in Cranes & Hoists, these can be offered in range from 2 HP to 100 HP according to the specific process requirements of the clients. Further, the superior Gear tooth geometry design also allows generation of maximum efficiency which includes –

These gearboxes provide ease of servicing along with rigid, robust and torsion resistant housing so as to ensure long services life standards. The housing is made from 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, suitable ribs are placed under bearing seats for high power with walls of adequate thickness to withstand many severe stresses faced during procedure. Additional, we also hold experience in providing housing in cast metal/fabricated steel finish if required.
