crane duty helical gearbox

Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against temperature generated when devices are operated at 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 metal that is duly heat treated and finished to high precision tolerance by grinding procedure, thus avoiding leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life along with high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either direction, working 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/individual mounted lubrication oil pump can be used for forced-feed lubrication.
Cooling Additional cooling systems provided inside lower part of housing depending on power to end up being transmitted and ambient temperature.
Overhung Loads Bearings may withstand overhung loads that occur due to mounting of smooth and V-belt pulleys, gear 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 construction features include:

Finding use 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 which includes –

Sizes
Dimensions
These gearboxes also provide ease of servicing as well as rigid, robust and torsion resistant crane duty helical gearbox casing in order to ensure long service life standards. The casing is constructed of quality close grained Grey Cast Iron that is proportioned to make sure proper radiation of temperature generated when the systems are operated at maximum capacity. Further, appropriate ribs are positioned under bearing seats for high strength with walls of enough thickness to withstand most serious stresses faced during operation. Additional, we also hold expertise in providing casing in cast metal/fabricated steel complete if required.
