crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure 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 created from medium carbon steel that is duly heat treated and finished to high precision tolerance by grinding process, thus stopping leakage of oil and entry of dust.
Bearings Antifriction bearings used to ensure 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 places where splash lubrication isn’t effective, a built-in/individual mounted lubrication oil pump can be used for forced-feed lubrication.
Cooling Additional cooling devices provided inside lower part of housing based on power to be transmitted and ambient temperature.
Overhung Loads Bearings can withstand overhung loads that arise because of mounting of toned and V-belt pulleys, equipment wheels and chain sprockets of suitable dimensions.
Painting Casting areas painted with linear epoxy primer (both internally and externally).

High load carrying capacity
Minimal noise generation
Some of the standard construction 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 needs of the clients. Further, the superior Gear tooth geometry style also allows era of maximum efficiency that includes –

These gearboxes also provide ease of servicing in addition to rigid, robust and torsion resistant casing in order to ensure long provider life standards. The housing is made of quality close grained Grey Cast Iron that is proportioned to make sure proper radiation of high temperature generated when the systems are operated at optimum capacity. Further, ideal ribs are placed under bearing seats for high power with walls of sufficient thickness to withstand the majority of severe stresses faced during procedure. Additional, we also hold knowledge in providing casing in cast steel/fabricated steel finish if required.
