crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against high temperature generated when units 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 made from medium carbon metal that is duly warmth treated and finished to high precision tolerance by grinding process, thus avoiding leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life and also high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either path, working in and functional test run is done in direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At places where splash lubrication is not effective, a built-in/individual mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling models provided inside lower component of housing based on power to be transmitted and ambient temp.
Overhung Loads Bearings may withstand overhung loads that occur because of mounting of toned and V-belt pulleys, gear 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
A few of the standard structure features include:

Finding make use of in Cranes & Hoists, these could be offered in range from 2 HP to 100 HP according to the specific process requirements of the clients. Further, the superior Equipment tooth geometry style also allows era of maximum efficiency that includes –

These gearboxes provide ease of servicing as well as rigid, robust and torsion resistant casing so as to ensure long assistance life standards. The casing is constructed of quality close grained Grey Cast Iron that is proportioned to make sure proper radiation of heat generated when the systems are operated at maximum capacity. Further, suitable ribs are placed under bearing seats for high power with walls of enough thickness to withstand most severe stresses faced during operation. Additional, we also hold experience in providing housing in cast steel/fabricated steel complete if required.
