crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against high temperature generated when models are operated in their 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 heat treated and finished to high precision tolerance by grinding process, thus avoiding leakage of oil and entry of dust.
Bearings Antifriction bearings used to ensure long service life along with high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either direction, working in and functional check run is done toward rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At places where splash lubrication is not effective, a built-in/individual mounted lubrication essential oil pump is used for forced-feed lubrication.
Cooling Additional cooling models provided inside lower part of housing based on power to be transmitted and ambient heat.
Overhung Loads Bearings may withstand overhung loads that arise 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 building features include:

Finding make use of in Cranes & Hoists, these can be offered in range between 2 HP to 100 HP according to the specific process requirements of the customers. Further, the superior Equipment tooth geometry style also allows era of maximum efficiency that includes –

Sizes
Dimensions
These gearboxes also provide ease of servicing along with rigid, robust and torsion resistant casing so as to ensure long service life standards. The housing is constructed of quality close grained Grey Cast Iron that’s proportioned to ensure proper radiation of warmth generated when the systems are operated at maximum capacity. Further, appropriate ribs are positioned under bearing seats for high power with walls of sufficient thickness to withstand most severe stresses faced during operation. Additional, we also hold knowledge in providing casing in cast steel/fabricated steel complete if required.
