crane duty helical gearbox

Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against temperature generated when products 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 made from medium carbon steel that is duly high temperature treated and finished to high precision tolerance by grinding process, thus avoiding leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life in addition to high process efficiency.
Path of rotation Though gearboxes are suitable for rotation in either path, running in and functional test run is done toward rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At places where splash lubrication isn’t effective, a built-in/separate mounted lubrication essential oil pump is used for forced-feed lubrication.
Cooling Additional cooling devices provided crane duty helical gearbox inside lower component of housing depending on power to become transmitted and ambient temp.
Overhung Loads Bearings may withstand overhung loads that occur due to mounting of toned 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
A few of the standard construction 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 clients. Further, the superior Equipment tooth geometry style also allows era of maximum efficiency which includes –

These gearboxes also provide ease of servicing and also rigid, robust and torsion resistant casing so as to ensure long provider life standards. The housing is constructed of quality close grained Grey Cast Iron that’s proportioned to make sure proper radiation of temperature generated when the devices are operated at optimum capacity. Further, ideal ribs are placed under bearing seats for high strength with walls of adequate thickness to withstand most severe stresses faced during procedure. Additional, we also hold expertise in providing housing in cast steel/fabricated steel complete if required.
