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 products 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 made from medium carbon metal that is duly heat treated and finished to high precision tolerance by grinding process, thus preventing leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life along with high process efficiency.
Direction of rotation Though gearboxes are suitable for rotation in either path, running 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 models provided inside lower part of housing based on power to be transmitted and ambient temp.
Overhung Loads Bearings may withstand overhung loads that arise because of mounting of toned 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 building features include:

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

These gearboxes also provide ease of servicing along with rigid, robust and torsion resistant casing in order to ensure long services life standards. The housing is constructed of quality close grained Grey Cast Iron that’s proportioned to ensure proper radiation of high temperature generated when the systems are operated at maximum capacity. Further, suitable ribs are placed under bearing chairs for high power with walls of enough thickness to withstand most severe stresses faced during procedure. Further, we also hold knowledge in providing housing in cast metal/fabricated steel complete if required.
