Abstract
The wheel assembly is an integral part of Electric Overhead Travelling Crane systems that are intended to move in a guided path.
Design is an important industrial activity which influences the quality of the product. There is research gap of optimization of
track wheel. It is always beneficial to optimize any component for the purpose where it is applicable. Optimization techniques
carried out for track wheel to find out the optimum material distribution. Based on these optimization outputs, new practical
designs were generated and FEanalysis was carried out for the optimized design to verify the stress induced on track wheeland
compare with original design. A solver mode in analysis software calculates the stresses, deflections, bending moments. The
finite element method as well as optimization techniques were included as basis of mathematical simulation. With these tools,
optimization of track wheel carried out.

I. INTRODUCTION
An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane
consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the
bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry
crane or a goliath crane. Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or
maintenance applications, where efficiency or down time are critical factors.

Overhead cranes are commonly used in the refinement of steel and other metals such as copper and aluminium. At every step of
the manufacturing process, until it leaves a factory as a finished product, metal is handled by an overhead crane. Raw materials
are poured into a furnace by crane, hot metal is then rolled to specific thickness and tempered or annealed, and then stored by an
overhead crane for cooling, the finished coils are lifted and loaded onto trucks and trains by overhead crane, and the fabricatoror
stamper uses an overhead crane to handle the steel in his factory. The automobile industry uses overhead cranes to handle raw
materials. Smaller workstationcranes, such as jib cranes or gantry cranes, handle lighter loads in a work area, such as cnc mill or
saw.
Almost all paper mills use bridge cranes for regular maintenance needing removal of heavy press rolls and other equipment.
The bridge cranes are used in the initial construction of paper machines because they make it easier to install the heavy cast iron

paper drying drums and other massive equipment, some weighing as much as 70 tons.In many instances the cost of a bridge
crane can be largely offset with savings from not renting mobile cranes in the construction of a facility that uses a lot of heavy
process equipment.
