At the small test facility where I work, we perform a 5 year maintenance task of inspecting our pipe hangers and adjusting the variable spring hangers as necessary. The problem is that the instructions for performing the adjustments do not mention whether you read the load from the top or the bottom of the indicator plate. According to the Anvil catalog, their variable pipe hanger loads are read from the bottom of the indicator. Is this the same for all brands, types, and model years of variable pipe hangers? I ask this because the plant was built in the late 1950's and then expanded in 1964 and again in 1984, so there are multiple brands and model years of variable spring hangers (i.e. AEC, Blaw Knox, Bergen-Patterson, PPC, PSS-Grinnell, and Anvil) throughout our plant.
