Best Practice Tips for Hoistmen
Never move the hoist if a signal is not clear (Don't guess at bell signals)
Always check the cable after an unusual occurrence, i.e. coming off the sheave, drug across the coping
never move the hoist if the bell signal doesn't match the task you doing
Always move the hoist slowly if persons are working from scaffolds
Remember your last move
Always communicate with the hole boss
Keep the boom dogged when you are not using it
If hoist gets out of control, press the E-stop
Pay attention to the sound of your motors and pumps when lowering equipment, etc. into the shaft
Don't let it cavitate
Keep your attention focused on the task at hand
Always keep an eye on the drum
Don't put your trust in the dial indicator
Use as a general guide
Run slabs in with the limit switch engaged
Always do a self-evaluation at the beginning of the shift for work fitness
Ensure brake test is done prior to shift
Test cable and chain loads prior to shift
Don't swing and drag items on the ground with the hoist
Always make sure you have 3 wraps left on the drum
Don't continue operating hoist if you feel something is not right - stop and have it checked out
