Electric Over-head Travelling Crane Gear Box has long life and is maintenance free. The Box has cast iron made rigid, robust, torsion resistant housing to dampen vibration and resist the heat maximum capacity offered in most modern foundry in house. The Box has anti-friction bearings of ample size is used throughout to ensure long service life and the use of antifriction bearings ensure high efficiency, correct centre distance and proper shaft alignment. The Box has shaft extensions which are fitted with quality grade seals to prevent oil leakage and dust entry. The Box has lubrication for normal speeds and splash lubrication is provided by gears dipping in oil and the oil level indicator located in the housing is to ensure a proper amount of lubricant in the housing. The Box has shafts having pinions cut integral are of heat treated alloy steel bars or alloy steel forging and all other shafts are of heat-treated carbon steel and are finished to high precision tolerance by grinding. The Electric Over-head Travelling Crane Gear Box has the feature that the heat generated within the gear units is dissipated by a sufficiently large surfaced area of the housing for higher capacities additional cooling is provided by fans, cooling inside lower housing depending on heat dissipation requirement based on power to be transmitted and ambient temperature.
