crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against temperature generated when units are operated in 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 preventing 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 suitable for rotation in either direction, running in and functional check 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 utilized for forced-feed lubrication.
Cooling Additional cooling models provided inside lower component of housing based on power to end up being transmitted and ambient heat range.
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 construction 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 Equipment tooth geometry style also allows generation of maximum efficiency that includes –

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