Trial lift, inspection, and proof testing
Arkansas Code § 23-89-508
(a)
- (1) A trial lift with the unoccupied platform loaded at least to the anticipated lift weight shall be made from ground level, or any other location where persons will enter the platform, to each location at which the platform is to be hoisted and positioned.
- (2) The trial lift shall be performed immediately prior to placing personnel on the platform.
- (3) The operator shall determine that all systems, controls, and safety devices are activated and functioning properly, that no interferences exist, and that all configurations necessary to reach each location will allow the operator to remain under the fifty-percent limit of the hoist's rated load capacity.
- (4) A single trial lift may be performed at one time for all locations that are to be reached from a single set up position.
- (b) The trial lift shall be repeated daily or when the portable tower is moved and set up in a new location or returned to a previously used location.
(c) Persons shall not be hoisted unless:
- (1) Hoist ropes are free of kinks;
- (2) Multiple part lines are not twisted around each other; and
- (3) The primary attachment is centered over the platform.
- (d) The hoisting system shall be inspected if the load rope is slack to ensure all ropes are properly seated on drums and in sheaves.
- (e) A visual inspection of the portable tower, rigging, platform, and the tower base support or ground shall be conducted by a person designated by the jump master immediately after the trial lift to determine whether the testing has exposed any defect or produced any adverse effect upon any component or structure.
- (f) Any defects found during inspections which create a safety hazard shall be corrected before hoisting personnel.
- (g) Documentation of the trial lift and daily preoperational lift shall be made available to the Division of Labor.
