Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against heat generated when products are operated in their maximum capacity
Helical Gears & crane duty helical gearbox Pinion Shafts These have 
involute profile teeth and so are constructed using high alloy case hardening steel.
Shafts Low speed shafts created from medium carbon steel that is duly heat treated and finished to high precision tolerance by grinding procedure, thus stopping leakage of oil and entry of dust.
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, working 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/individual mounted lubrication oil pump can be used for forced-feed lubrication.
Cooling Additional cooling models provided inside lower component of housing depending on power to be transmitted and ambient heat.
Overhung Loads Bearings can withstand overhung loads that occur due to mounting of flat and V-belt pulleys, gear 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 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 needs of the customers. Further, the superior Equipment tooth geometry style also allows generation of maximum efficiency that includes –
Sizes
Dimensions
These gearboxes also provide ease of servicing as well as rigid, robust and torsion resistant housing in order to ensure long support life standards. The housing is made from quality close grained Grey Cast Iron that is proportioned to make sure proper radiation of temperature generated when the devices are operated at optimum capacity. Further, suitable ribs are placed under bearing chairs for high power with walls of enough thickness to withstand most serious stresses faced during operation. Additional, we also hold experience in providing housing in cast metal/fabricated steel complete if required.
