We design tailor made applications involving Lead Screw Mechanisms One such application refers to PORTAL BRIDGE at NCPA Theater where in 5 Tonne weighing Portal Bridge is moved vertically Upwards and Downwards by means of Two Screws with Motor at the Centre.   In case of Bevel jacks we use Teeth generated case hardened Bevel Gears. •    We are specialised in designing and manufacturing special purpose or custom built screw applications. •    The picture shows a typical screw jack designed to lift 2.5Tonnes for some export application. •    Bellows used for protection from dust and atmospheric corrosion. •    Precision Trapezoidal screw M30x7P, Taiwan make is used. •    We also manufacture Screw Jacks of different capacities with imported Trapezoidal Screws.

From staff control room of the simulator, flood valves and drain valves are operated by means of our Rod gearing mechanism. Universal mounting type specially designed bevel gear box units are typically used to transmit the motion from staff control room up to the valves situated at the base of the simulator at various locations. This facilitates simulation of sinking conditions and Naval staff is trained how to cope up with the situation. The project was handled for Electropneumatics and Hydraulic India Ltd, who in turn have supplied the vessel to Indian Navy.

Heating Burners are swivelled and raised up-down by means of a gearbox and a Screw Jack respectively. Compact plant is designed to cater the requirement. The whole assembly can be raised or lowered up/down and also individual burners can be tilted and/or moved in linear manner as and when required.  

We have been manufacturing Special purpose Gearbox with Geneva mechanism to deliver Output Torque of 3.2 KN-Mt with 10 H.P. Motor, intermittently.   This is a typical application used for intermittent motion in Grating manufacturing plant. The temporary dwell period is used for electro forged welding of Gratings on a conveyor. This is an import substitute continuous duty application.     GENEVA GEAR BOX INPUT 10 HP 1440 RPM RAIO; WORM REDUCTION 49:1 TIME OF INDEXING – 0.8276 SECONDS; RESTING TIME – 1.2414 SECONDS MAX.

Special Purpose Hoist Mechanisms used in Television and other Studios.     We have designed and developed Special Heli Worm Gearbox with Self Locking characteristics to lift and lower Lighting Grid ( 200 Kg to 2.5 Tonnes) by means of Ropes and Rope Drums. For lighter weight applications like 200 Kg and 400 Kg we have Self Climbing Hoists also. These Hoist differs from normal Industrial hoists in a way that the Gears are always loaded and this requires Self Locking characteristics.   This Motorized Lighting Grid is being used to install Lights along with service persons to cover desired area for Lighting for Film Shoots.   Motorized Gear Box with Self Locking Characteristic along with Rope winding mechanisms with different capacities have been used for handling Lighting Grids and other equipment used for Photography and Shooting.   This facilitates easy adjustments of Lights in any studio as per the requirement. Similar mechanism is being used at AERI Pune for recording Crash Test of Automobiles.  

We have a range of precision small Gearboxes to be used with Fractional Horse Power Motors. We are specialized in designing and manufacturing import substitute precision small gearboxes for Geared Motor application. These motors find a wide application in Original Equipment Manufacturing Industry. We have handled many tailor made projects involving making small gearboxes (worm , Bevel, Planetary or Helical) suitable for desired application.     Motors vary from 30 watts to 370 watts and AC as well as PMDC types. We can even provide adapter units for our gearboxes to be coupled with different Motors also. We have various models like Inline Helical Gearbox, Worm Gearbox in pressure Die Cast Housings, Worm Gearbox with Hollow Output Shaft, Double Reduction Gearbox and so on. We design and manufacture prototypes for import substitute small Gearboxes for various applications. We manufacture precision small Gearboxes of all types like Helical Gearboxes, Worm Gearboxes, Bevel Gearboxes for Motorized applications.

  Special Purpose Gear Box with Self Locking Characteristic for Engine Mounting Trolley     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. This is a Service Tool End User: Fiat India Ltd. TATA MOTORS, MAHINDRA & MAHINDRA LTD. Besides we have also developed various Service Tools for the similar applications.      

Bevel G This is a typical application where in synchronized motion transfer is required to operate different units     simultaneously in a blister packing machine. •  The concept was explained to us and we have engineered the solution. •  The drive is 3HP servo motor with a worm gearbox reduction. •  Teeth generated Bevel Gears with high accuracy and case hardened are used. •  Least amount of backlash has been maintained. •  There are One Input and 3 Output shafts in one plane and besides another shaft id extended downwards to give one more output. •  SKF or equivalent make ball bearings are used. •  Lubrication is appropriate grade Grease to avoid leakages earboxes with 4 Output shaft

We have handled this project for Shipbuilding Division, Larsen and Toubro Ltd, Hazira Yard. We have designed and manufactured system comprising of special purpose bevel gearbox to operate various valves from remote locations for the purpose of convenience of operations. We have used bevel gearboxes for change in direction of rotations besides Rods, Pedestal Bearings and Universal Couplings are used.   Small compact bevel gearboxes with precise teeth generated Bevel Gears used inside are developed by us for this application.   We have even provided Bonnet Assemblies with asbestos free Gland Seals at appropriate Locations.     We have successfully completed a prestigious project for Shipbuilding Department Larsen and Toubro Ltd. Hazira works. We have offered complete solution for Remote Operation of Valves located at inconvenient locations inside a Ship. We have also carried out commissioning at site (Ship). The project was completed in record time period and upto the mark with remarkable fine operations of valves at various locations along with providing asbestos free gland packing with meticulous planning.
