crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against warmth generated when units are operated in 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 heat treated and finished to high precision tolerance by grinding process, thus preventing leakage of oil and entry of dust.
Bearings Antifriction bearings used to ensure long service life and also high process efficiency.
Direction of rotation Though gearboxes are ideal for rotation in either path, running in and functional test run is done in direction of rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At places where splash lubrication isn’t effective, a crane duty helical gearbox built-in/individual mounted lubrication essential oil pump is used for forced-feed lubrication.
Cooling Additional cooling models provided inside lower component of housing based on power to become transmitted and ambient heat.
Overhung Loads Bearings can withstand overhung loads that arise due to mounting of flat and V-belt pulleys, equipment 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
CONSTRUCTION FEATURES
Some of the standard structure features include:

Finding make use of in Cranes & Hoists, these can be offered in range from 2 HP to 100 HP as per the specific process requirements of the clients. Further, the superior Gear 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 housing in order to ensure long service life standards. The casing is constructed of quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of heat generated when the systems are operated at optimum capacity. Further, ideal ribs are positioned under bearing chairs for high strength with walls of adequate thickness to withstand the majority of severe stresses faced during procedure. Further, we also hold experience in providing casing in cast metal/fabricated steel complete if required.
