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 products are operated in their maximum capacity

Shafts Low speed shafts created from medium carbon steel that is duly temperature treated and finished to high precision tolerance by grinding procedure, thus preventing leakage of essential oil and entry of dirt.
Bearings Antifriction bearings used to ensure long service life in addition to high process efficiency.
Direction of rotation Though gearboxes are suitable for rotation in either direction, working in and functional test run is done toward rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At places where splash lubrication isn't effective, a built-in/individual mounted lubrication oil pompa can be used for forced-feed lubrication.
Cooling Additional cooling units provided inside lower component of housing based on power to become transmitted and ambient heat range.
Overhung Loads Bearings can withstand overhung loads that occur due to mounting of flat and V-belt pulleys, equipment wheels and chain sprockets of appropriate dimensions.
Painting Casting areas painted with linear epoxy primer (both internally and externally).

High load carrying capacity
Minimal noise generation
CONSTRUCTION FEATURES
A few of the standard building features include:

Sizes
Dimensions
These gearboxes provide ease of servicing and also rigid, robust and torsion resistant casing in order to ensure long services life standards. The casing is made from quality close grained Grey Cast Iron that's proportioned to ensure proper radiation of temperature generated when the units are operated at maximum capacity. Further, suitable ribs are positioned under bearing seats for high power with walls of adequate thickness to withstand the majority of serious stresses faced during procedure. Additional, we also hold expertise in providing casing in cast metal/fabricated steel complete if required.
