MSI 4260 B Port-A-Weigh Crane Scale

With the introduction of the original MSI-4260 Port-A-Weigh in 1979, it quickly replaced mechanical crane scales in the Alaskan fishing industry. Exceptional ruggedness and accuracy made it the only legal-for-trade scale for a harsh marine environment. With periodic design updates, the MSI-4260 remains the workhorse of the heavy-duty crane scale market.

Intrinsically Safe configurations now available for FM Class 1 Div 1 and ATEX



The NTEP approved Port A Weigh  with an accuracy of 0.1% of the applied load, is approved for use in legal for trade applications.  The Port-A-Weigh's rugged, NEMA IV enclosure provides you many years of dependable operation in the harshest industrial and marine applications. With the Factory Mutual option the scale is approved for use in flammable environments, and with an optional configuration it is ideally suited for high-heat applications. With standard capacities that range from 500 pounds to 50 tons, you can use a Port-A-Weigh for virtually any overhead weighing need.


Some of the more additional features you get with a Port-A-Weigh include: shock-mounted electronics, rugged cast aluminum alloy housing, 50 hours of continuous operation between battery charges, and digital filtering for superior readout stability .
