Gear Boxes and couplings are the HEART of any crane are responsible to a major extent for the performance reliability. The gear units use HARDENED & PROFILE GROUND HELICAL GEARS in R 20 series running silent oil bath and vibration free steel fabricated stress relieved or graded cast iron housing. The gear unit have long life and are almost maintenance free. All gears, pinions and gear boxes conform to DIN-6AGMA-12 tolerances. The weightpower ratio is optimised by the use of case hardened low carbon alloy steels of high strength (58-62 HRC). The gear reduction efficiency obtained is as high as 99% per reduction.

Pendent, cabin or RadioInfrared Remote operated cranes can be supplied in any mode or a combination of modes. Adequate protection by way of single phasing, phase reversal, overloads, embedded thermistors are some of the standard features. Provision for Dynamic Braking and soft start can bemade. Cranes with variable speed drives suitable for slipring squirrel cage motors for precise handling can also be supplied. (All components used are of standard internationally reputed make). The steel-metal housings are constructed to accept the power & control circuits in a single cubicle having built in cable trench underneath. The spacings and marking are as per IS specifications. The design permits easy maintenance & protects the cables are being incorporated for maximum reliablility and trouble free operations. Cabin Constructed from Sheet-Metal the Cabin are suspended either on one side of the crane or in the middle. These are either open type for indoor use or closed types for out-door use. Air-conditioned cabins can also be supplied. All cabins have a protective panel & controls are ergonomically placed for maximum comfort to the operator.

The drum is coupled to the gear box via drum coupling that facilitates easy removal and maintenance if needed. Wire rope is fixed with double slot clamps. Non-rotating, high strength special Hyflex wire ropes manufactured for use on hoisting equipment are used, with factor of safety as per relevant IS standards.
