Abstract: This paper deals with design of walking beam pendel
axle suspension system. This axles and suspension systems are
mainly required for transportation of heavy duty and Over Dimension
Consignment (ODC) cargo, which is exceeding legal limit in terms of
length, width and height. Presently, in Indian transportation industry,
ODC movement growth rate has increased in transportation of bridge
sections (pre-cast beams), transformers, heavy machineries, boilers,
gas turbines, windmill blades etc. However, current Indian standard
road transport vehicles are facing lot of service and maintenance
issues due to non availability of suitable axle and suspension to carry
the ODC cargoes. This in turn will lead to increased number of road
accidents, bridge collapse and delayed deliveries, which finally result
in higher operating cost. Understanding these requirements, this work
was carried out. These axles and suspensions are designed for
optimum self – weight with maximum payload carrying capacity with
better road stability.
