crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against temperature generated when devices are operated in their maximum capacity
Helical Gears & Pinion Shafts These possess 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 warmth treated and finished to high precision tolerance by grinding procedure, thus stopping leakage of oil and entry of dirt.
Bearings Antifriction bearings used to ensure long service life along with high process efficiency.
Direction of rotation Though gearboxes are ideal for rotation in either path, operating in and functional check run is done in direction of rotation specified.
Lubrication For regular 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 units provided inside lower part of housing based on power to become transmitted and ambient temperature.
Overhung Loads Bearings can withstand overhung loads that arise because of mounting of smooth 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 structure features include:

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

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

For those whose enthusiasm is crane duty helical gearbox, we have the responses.
