Jacks and Hoists

Self-Inspection Checklist

Guidelines

This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under general industry standards 29 CFR 1910.244 and 1910.308 and the construction standards 29 CFR 1926.305 and 1926.554. These regulations cover jacks, overhead hoists, and monorail hoists. The regulations cited apply only to private employers and their employees, unless adopted by a state agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA or EPA standard, or with a nonregulatory recommendation. Definitions of terms in bold type are provided at the end of the checklist.

    Electric Monorail Hoists

17. On an electric monorail hoist, is a readily accessible disconnecting means provided between the runway contact conductors and the power supply? [29 CFR 1910.306(b)(1)(i)]
18. On an electric monorail hoist, is another disconnecting means (capable of being locked in the open position) provided in the lead from the runway contact conductors or other power supply? [29 CFR 1910.306(b)(1)(ii)]Note: See 29 CFR 1910.306(b)(1)(ii)(B)(1 to 3) for exceptions.
19. If the additional disconnecting means required in question 17 is not readily accessible from the crane or monorail hoist operating station, is a means provided at the operating station to open the power circuit to all motors of the crane or monorail hoist? [29 CFR 1910.306(b)(1)(ii)(A)]

21. On an electric hoist where controls are enclosed in cabinets, are door(s) removable or capable of opening at least 90 degrees? [29 CFR 1910.306(b)(3)]
22. Is a limit switch or other device provided to prevent the load block from passing the safe upper limit of travel of any hoisting mechanism? [29 CFR 1910.306(b)(2)]
