Final answer:
The statement regarding the introduction of PU wheels in the 1960s positively impacting the material handling industry is true. These wheels provided considerable advantages such as better traction, noise reduction, and increased durability.
Step-by-step explanation:
The introduction of polyurethane (PU) wheels in the 1960s indeed marked a significant turning point in the material handling industry. This innovation greatly improved the way goods were moved and stored, making it a true statement. PU wheels provided a number of advantages over the traditional materials used for wheels, such as steel or rubber.
PU wheels brought about a revolutionary change by offering improved traction, reduced noise levels, and better wear resistance when compared to their predecessors. These benefits not only made operations more efficient but also increased the lifespan of the equipment. Furthermore, PU wheels were less damaging to floor surfaces, which reduced maintenance costs and downtime for businesses. Their introduction also coincided with overall developments in logistics and supply chain management during that era, illustrating the broader context of innovation within the industry.
