crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against high temperature generated when devices are operated at their maximum capacity
Helical Gears & Pinion Shafts These have involute profile teeth and so are constructed using high alloy case hardening steel.
Shafts Low speed shafts made from medium carbon metal that is duly heat treated and finished to high precision tolerance by grinding process, thus preventing leakage of oil and entry of dust.
Bearings Antifriction bearings used to ensure long service life along with high process efficiency.
Direction of rotation Though gearboxes are suitable for rotation in either direction, operating in and functional check run is done in direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At areas where splash lubrication is not effective, a built-in/individual mounted lubrication oil pump is used for forced-feed lubrication.
Cooling Additional cooling devices provided inside lower component of housing based on power to be transmitted and ambient heat.
Overhung Loads Bearings can withstand overhung loads that occur due to 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
CONSTRUCTION FEATURES
Some 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 Equipment tooth geometry design also allows generation of maximum efficiency which 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 constructed of quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of heat generated when the products are operated at optimum capacity. Further, suitable ribs are placed under bearing chairs for high strength with walls of sufficient thickness to withstand the majority of severe stresses faced during procedure. Additional, we also hold expertise in providing casing in cast steel/fabricated steel complete if required.
