Michigan Administrative Code › Department - Labor and Economic Opportunity › MIOSHA › General Industry and Construction Safety and Occupational Health Standards › Construction Safety and Health Standard › Part 28 - PERSONNEL HOISTING IN STEEL ERECTION › Section R. 408.42809 - Personnel hoisting

Current through Vol. 24-12, July 15, 2024
Rule 2809.
(1)
					 All the provisions of construction safety standard Part 26. "Steel Erection"
					 being R 408.42601 to R 408.42655, which is referenced in R 408.42806, apply to
					 all hoisting.
(2) Riding the
					 headache ball is prohibited except when the work area is inaccessible or
					 hazardous to reach by other means, a maximum of 2 connectors may ride the
					 headache ball to and from the workstation with the knowledge and consent of the
					 employer or the employer's designated representative. The connector or
					 connectors may be lifted to the workstation only when all of the following
					 conditions exist:
(a) Connectors riding a
					 load line standing platform shall be protected from falling by a positioning
					 device system or a personal fall arrest system as prescribed in construction
					 safety standard Part 45. "Fall Protection," R 408.44501 to R 408.44502 which is
					 referenced in R 408.42806.
(b) The
					 connector or connectors and his or her immediate supervisor, who shall be a
					 competent person, and the operator who will perform the lift shall verbally
					 agree and certify in writing that using the load line standing platform is the
					 safest alternative. They shall plan the lift together to minimize the transport
					 distance. A minimum distance of 20 feet shall be maintained between the load
					 line standing platform and the top sheave.
(c) A load line standing platform shall be a
					 minimum of 3/8 of an inch thick steel plate not less than 12 inches nor more
					 than 18 inches in diameter and shall provide means for slip resistant footing.
					 The platform shall be secured in such a manner to prevent tipping and shall be
					 placed between the headache ball and the wedge socket.(See figure 1.) As an
					 alternative, a shackle rated not less than 25 tons may be used. (See figure 2.)

(d) No
					 rigging or load shall be attached to the crane or derrick during the use of a
					 load line standing platform by the connector or connectors.
(e) The maximum rate of travel for the
					 connector or connectors riding the load line standing platform shall be 100
					 feet per minute. Free-spooling and live booms are prohibited. Controlled load
					 lowering shall be used when the load line standing platform is used to lower
					 the connector or connectors.
(f)
					 There shall be a communication system between the connector or connectors on a
					 load line standing platform and the operator of the crane or derrick. The
					 system may be hand signals or a closed 2-way selective frequency radio system.
					 Hand signals shall be followed according to appendix A of this part.
(g) An operator of a crane or derrick shall:
(i) Not be authorized to raise or lower the
					 connector or connectors on a load line standing platform unless the operator is
					 certified by the national commission for the certification of crane operators
					 or an equivalent crane certification organization.
(ii) Be trained in all of the provisions of R
					 408.42809(2) before being allowed to transport the connector or connectors on a
					 load line standing platform.
(h) When a load line standing platform is in
					 use by the connector or connectors, the operator of a crane or derrick shall
					 maintain the minimum distance from an energized power transmission or
					 distribution line as required in table 1, as follows:
VOLTAGE
MINUMUM CLEARANCE
Up to 50 kV
20 feet
Over 50 kV
20 feet + 0.8 inch per kV over 50 kV
(i) The load line of a crane or derrick that
					 is used to raise or lower the connector or connectors on a load line standing
					 platform shall have a safety factor of 10 for the anticipated load, and be
					 equipped with a swivel to prevent any rotation of the load line standing
					 platform. A minimum of 1/2-inch diameter load line shall be used.
(j) Neither the load line standing platform
					 nor the boom shall be lowered below the point where less than 3 full wraps of
					 the wire rope remain on their respective drums.
(k) A crane or derrick that is used to raise
					 or lower a load line standing platform shall be set level according to the
					 crane or derrick manufacturer's specifications. The travel lock shall be
					 engaged on a crane when the load line standing platform is in use.
(l) A crane that is equipped with outriggers
					 shall have the beams and jacks fully extended to provide maximum stability and
					 the floats shall have a stable bearing when the load line standing platform is
					 in use by the connector or connectors. A crawler crane shall have its crawlers
					 fully extended when the load line standing platform is in use.
(m) Where a crane or derrick will be used to
					 elevate the connector or connectors on the load line standing platform to an
					 area where there has been no previous lift of structural members, a trial lift
					 shall be performed and consist of positioning the load line standing platform
					 to the position it is to be used with an assumed minimum anticipated load of
					 1,000 pounds. The operator shall determine that all configurations necessary to
					 reach the work location will allow the crane or derrick to remain under the 50%
					 limit of the hoisting capacity; that all systems, controls, and safety devices
					 are activated and functioning properly; and that interferences do not exist.
					 This will be done at each set-up location of a crane or derrick prior to
					 elevating the connector or connectors.
