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 created from medium carbon steel that is duly warmth treated and finished to high precision tolerance by grinding process, thus preventing leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to ensure long crane duty helical gearbox service life along with high process efficiency.
Direction of rotation Though gearboxes are ideal for rotation in either path, operating in and functional check run is done in direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At locations 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 component of housing depending on power to become transmitted and ambient heat range.
Overhung Loads Bearings can withstand overhung loads that occur due to mounting of smooth and V-belt pulleys, gear 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
CONSTRUCTION FEATURES
A few of the standard structure features include:

Finding make use of in Cranes & Hoists, these could be offered in range between 2 HP to 100 HP as per the specific process requirements of the clients. Further, the superior Equipment tooth geometry design also allows generation of maximum efficiency which includes –

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