CLOSE
ASME B16.48 said that spade handles may have no openings.
For spades, which can be lift up by people that's no problem, but for a spade that weighs hundreds of kilograms, a lifting ability is needed.
So it is usual, that from a certain weight and size, a hole at the top of the handle is made to give a lifting possibly.
Many companies have their own rules, about the implementation of a spade handle, so there are many different types and designs.
Further General notes:
- Ring Spacer Handles shall have a single through indicator hole located near the end of the handle. The hole diameter shall not be less than 12 mm.
- Wt = Thickness of the handle should be 6 mm minimum, or equal to Thickness (t) if less than 6 mm.
- Spades and Ring Spacers should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges and piping involved.
- Depending on a customer specification, some dimensions can be different from what on this page is defined.
