In contemporary times, leaf springs have gained popularity in the realm of large commercial vehicles like trucks, SUVs, and vans. Also referred to as transmission springs, these leaf springs offer a simplistic design commonly found in wheeled vehicles. One advantage of trolley leaf springs over conventional helical springs is their ability to orient the tips of the leaves in specific directions.

Oswal Auto Industries leads the industry as a premier manufacturer of Trolley Leaf Springs, producing robust leaf springs suitable for attachment to the frame or directly to one end of a trolley. Typically, these springs are installed via a connection, often a small swing arm. During compression, the bond absorbs the slope of the leaf spring and elongates, thereby exhibiting elasticity and ductility.
