Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against high temperature generated when units are operated at their crane duty helical gearbox maximum capacity
Helical Gears & Pinion Shafts These have involute profile teeth and are constructed using high alloy case hardening steel.
Shafts Low speed shafts created from medium carbon steel that is duly high temperature treated and finished to high precision tolerance by grinding process, thus avoiding leakage of oil and entry of dirt.
Bearings Antifriction bearings used to ensure long service life as well as high process efficiency.
Direction of rotation Though gearboxes are ideal 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 is not effective, a built-in/separate mounted lubrication essential oil pump is used for forced-feed lubrication.
Cooling Additional cooling units provided inside lower part of housing based on power to become transmitted and ambient heat.
Overhung Loads Bearings can withstand overhung loads that occur due to 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
CONSTRUCTION FEATURES
A few of the standard structure features include:

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

Sizes
Dimensions
These gearboxes provide ease of servicing as well as rigid, robust and torsion resistant housing in order to ensure long support life standards. The casing is made of quality close grained Grey Cast Iron that is proportioned to make sure proper radiation of warmth generated when the devices are operated at maximum capacity. Further, ideal ribs are positioned under bearing seats for high power with walls of sufficient thickness to withstand many serious stresses faced during operation. Further, we also hold knowledge in providing housing in cast metal/fabricated steel finish if required.
