crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against warmth generated when models are operated at their maximum capacity
Helical Gears & Pinion Shafts These have 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 procedure, thus preventing leakage of oil and entry of dust.
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 path, operating in and functional test run is done toward rotation specified.
Lubrication For normal speeds, splash crane duty helical gearbox Lubrication is provided. At places where splash lubrication isn’t 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 depending on power to end up being transmitted and ambient temperature.
Overhung Loads Bearings can withstand overhung loads that arise due to mounting of flat and V-belt pulleys, gear wheels and chain sprockets of suitable dimensions.
Painting Casting surfaces 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 as per the specific process needs of the clients. Further, the superior Equipment tooth geometry style also allows era of maximum efficiency that includes –

These gearboxes provide ease of servicing along with rigid, robust and torsion resistant casing so as to ensure long assistance life standards. The casing is made from quality close grained Grey Cast Iron that is proportioned to make sure proper radiation of heat generated when the units are operated at optimum capacity. Further, appropriate ribs are positioned under bearing seats for high power with walls of sufficient thickness to withstand the majority of serious stresses faced during procedure. Additional, we also hold knowledge in providing housing in cast metal/fabricated steel finish if required.
