SAW/ARC/MIG/TIG welding machines, bending and rolling machines, special holding and rotating equipment for efficient welding, surface treatment (shot/sand blasting), heat treatment etc. The same equipment is finish machined on imported floor and horizontal borers, vertical turret lathes, heavy duty turning lathes, floor drills, gear cutting hobbers etc. ASHOKA Heavy Fabrication Work Capacity has a lifting and handling capacity of 75 MT single piece.
The structure is fabricated from specified steel grades including IS 2062 / SA 516 etc. which are cut to accurate sizes and subject to proper heat treatment for release of stresses.
Gearboxes of special crane duty class with accurately hob cut gear internal which may be hardened and ground as per requirement and load.
Rope Drum are made up of seamless pipe accurately machine grooved and mounted on self-align ball bearings for smooth running. Rope guide is provided for proper winding of the rope in drum groove.
End Carriages are of robust construction, standardized according to design aspect which gives perfect alignments, parallelism and perpendicularity of the wheels.
Wheels are made from special alloy steels such as Chrome Molybdenum steels and are hardened to 40 HRc. Wheels are shrunk fit on their axles. The crane wheels are housed in a manner so that they can be easily replaced.
Brakes are of electro-hydraulic thruster brakes particularly for use in overhead traveling cranes located suitably. In traveling motions electromagnetic fail-to-safe shoe or disc type brakes are mounted directly on motors.
Limit Switches of snap action type roller switches are generally provided.
