crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against high temperature generated when models are operated at their maximum capacity
Helical Gears & Pinion Shafts These possess involute profile teeth and 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 direction, operating in and functional test run is done toward rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At areas where splash lubrication isn’t effective, a built-in/separate mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling models provided inside lower part of housing based on power to be transmitted and ambient temperature.
Overhung Loads Bearings may withstand overhung loads that occur because of mounting of flat and V-belt pulleys, gear 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
Some of the standard structure features include:

Finding use in Cranes & Hoists, these could 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 which includes –

These gearboxes provide ease of servicing as well as rigid, robust and torsion resistant casing in order to ensure long services life standards. The housing is made from quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of warmth generated when the devices are operated at optimum capacity. Further, suitable ribs are placed under bearing chairs for high strength with walls of adequate thickness to withstand most serious stresses faced crane duty helical gearbox during operation. Additional, we also hold knowledge in providing casing in cast steel/fabricated steel complete if required.
