Structural design is the methodical investigation of the stability, strength and rigidity of structures.

The basic objective of structural design and analysis is to produce a structure capable of resisting all applied loads without failure during its operations and intended life.

The structural design involves establishing the loads and forces acting on equipment where structure is subjected to thrust, shear, bending and twisting and combination of loads as well as deflection, strain, stress intensities and reactions produced by loads.

Finally comes the proportioning of shape, size and selection of materials for the members and connections to respond adequately to the effects produced by the loads and operating conditions.


Main frame is the backbone of an off-highway equipment & this needs to be designed for durability, flexibility and versatility. We design the chassis/frame to take care of bending and torsional loads encountered during operation of the equipment.

We build full-scale prototypes and physically test them at NABL approved laboratories for structural strength, durability and vibration.
