The strength and durability of iron castings make it a key part of construction and material handling equipment such as excavators, wheel loaders, articulated haulers, truck mixers, road rollers, compactors, graders, warehouse trucks, and fork lifters. Due to their harsh working environment, the mechanical properties, dimensional tolerances, and surface treatment are the key factors for these machinery parts.
