Introduced in 1980, the MSI-4260 Port-A-Weigh established the original industry standard for accurate, reliable, and safe overhead crane weighing. After three decades of production, added advancements, and thousands of worldwide installations, the next generation Port-A-Weigh embedded with "ScaleCore" technology continues to reign as the industry standard.

For medium- to heavy-capacity needs, the MSI-4260 "Port-A-Weigh" has an established reputation as the industry standard in overhead weighing. MSI-4260 meets or exceeds all industrial safety requirements, including OSHA, ANSI and ASME, and is an economical choice for many bridge crane, foundry, and in-process material handling needs.
