So I have quite a few fixtures that weigh between 100-300 lbs and loading them on the CMM always requires pulling help from outsiders. I try to use the same people since they already know the importance of caution and careful placement but I would prefer a one man method. Now an engine hoist would work in most cases and I have used them in the past however gages always swing around and while I could most likely control it the 2nd shift operator is a small, older woman that would struggle with the heavier fixtures. Also, Murphy's Law will eventually take out the CMM or damage a fixture.
What are some methods you all have used for putting heavy things on the CMM by yourself that you felt was safe and controlled?
overhead crane on rails, with a 1/2 - 1 Ton rated load is ideal.
They sell "little" electric lift dollies that can handle 330-500lbs for under $2k. If you line the bottom of the fixtures with HDPE, you can use this to vertically lift the fixtures, then laterally sliding them off and on the grid or surface plate will be like butter with the HDPE bases.
the lift dolly i'm describing is like this one:
