R 408.11861 General conduct of operators.

Rule 1861. (1) An operator, when starting on duty shall comply with both of the following provisions: (a) Shall not close the main switch or emergency contactor until checking to see if anyone is on the crane and if a warning sign is on the crane, hook, or main switch. (b) Shall test all controls, limit switches, and brakes. When a load approaches the rated load, the operator shall test the hoisting brakes by raising the load a few inches and applying the brakes. (2) A hoisting limit switch on a crane or hoisting means shall not be used as an operating control unless the crane is also equipped with a backup limit switch. (3) A load shall not be lowered below a point where less than 2 full wraps of wire rope remain on the hoisting drum. (4) If there is doubt concerning the safety of a crane or hoisting means, then an operator shall stop the crane and report the condition creating the doubt to the supervisor. (5) In case of power failure, an operator shall place all controllers in the "off" position. (6) An operator leaving a crane unattended shall land any attached load, place the controllers in the "off" position, and open the main switch. Before closing a main switch, an operator shall make sure all controllers are in the "off" position. The main switch need not be opened on a pendant-controlled crane if the crane is left unattended for short periods.
