The operation of an overhead hoist involves more than activating the hoist’s controls. Per the ANSI/ASME B30
standards, the use of an overhead hoist is subject to certain hazards that cannot be mitigated by engineered features,
but only by the exercise of intelligence, care, common sense, and experience in anticipating the effects and results of
activating th
e hoist’s controls. Use this guidance in conjunction with other warnings, cautions, and notices in this manual
to govern the operation and use of your overhead hoist.
