Design and Manufacturing of Special Purpose Bevel Gear Boxes having Four Output Shafts, transmitting motion synchronously at various stages.

Application: Blister Packing Machine.
Client: Associated Capsule Group’s Pam Pac
Machine Pvt. Ltd. Mumbai
This was a first of its kind activity in the world executed for L&T and in turn for the final customer NPCIL, on their KGS 3 Atomic Reactor at Kaiga – Karnataka state. The task involved was to automate the grinding and
welding operation on a Weld joint in a live Atomic Reactor. The critical part of the activity was to execute grinding and welding in an ID of 145 mm from a distance of 2.5 meters making use of cameras for vision. The entire design of drive system, (consisting of planetary gear box, DC Motors, AC servo Motors & all related controllers etc.) manufacturing of the system components & trials was the scope taken up and executed successfully.
Design and Manufacturing of Complete Drive System with Self Locking Characteristic for rotating entire Rotor Assembly while inserting wound coils. Application Automation of Winding process of Rotors for 15 KW and above Generators.
Client: Siemens India Ltd. Kalwa Plant.
Design and Manufacturing of Special Purpose Gear Box with Self Locking Characteristic for Engine Mounting Trolley (Engine Overhauling Stand) This is a Hand operated Gear Box, with extended shaft. Automobile engine to be overhauled is mounted on the
shaft by means of special adapters fitted either at Bell Housing or at Exhaust manifold. This facilitates easy assembly of parts on the engine body. Used at automobile dealers/ Service stations.
End User: Fiat India Ltd. / TATA MOTORS. Besides We have also developed various Service Tools for the similar applications.
Design and Manufacturing of Special Purpose Hoist Mechanisms used in Television and other Studios. Motorized Gear Box with Self Locking
Characteristic along with Rope winding mechanisms with different capacities have been used for handling Lighting Grids and other equipments used for Photography and Shooting. This facilitates easy
adjustments as per the requirement.
Design and Manufacturing of complete Mechanism wherein Assembly of Two Bevel Gear Boxes with Splined Input and Output shafts to transmit Rotational Motion along with facility of Linear Movement between the two separate units. Used in Packaging Machine.
Besides these we have successfully handled several other Projects related to Design and
Manufacturing various types of assemblies. Photographs of few are as below.
