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 systems are operated at 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 steel that is duly warmth treated and finished to high precision tolerance by grinding process, thus preventing leakage of oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life as well as high process efficiency.
Path of rotation Though gearboxes are suitable for rotation in either direction, operating in and functional test run is done toward rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At areas where splash lubrication isn’t effective, a built-in/separate mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling devices provided inside lower part of housing based on power to end up being transmitted and ambient temp.
Overhung Loads Bearings can withstand overhung loads that arise because of mounting of smooth and V-belt pulleys, equipment wheels and chain sprockets of appropriate dimensions.
Painting Casting surfaces painted with linear epoxy primer (both internally and externally).

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

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

These gearboxes also provide ease of servicing as well as rigid, robust and torsion resistant casing in order to ensure long assistance life standards. The casing is made from quality close grained Grey Cast Iron that’s proportioned to make sure proper radiation of heat generated when the devices are operated at optimum capacity. Further, appropriate ribs are placed under bearing chairs for high strength with walls of sufficient thickness to withstand many severe stresses faced during procedure. Further, we also hold experience in providing casing in cast steel/fabricated steel complete if required.
