SCHEDULE 7(Subsections 336(1) and 343(1))Load Moment Indicator Systems
1 A load moment indicator system installed on a category 4 lifting appliance shall
(a) use the same type of measuring units that the load radius chart uses;
(b) clearly indicate the measuring units used;
(c) give a clear and precise indication of
(i) the lifting capacity of the appliance,
(ii) the total weight suspended,
(iii) the elevated angle of the boom, and
(iv) the radius of the boom;
(d) be clearly visible so that an operator seated at the control position can easily read the indications during both day and night conditions;
(e) be resistant to magnetic influence, weather, shock and vibration;
(f) have a visual system that
(i) warns the operator when 85% of the appliance’s SWL has been reached, and
(ii) does not create an operational hazard; and
(g) have a visual and audible system in the interior of the cab and an exterior audible system that
(i) warns the operator when 98% of the appliance’s SWL has been reached,
(ii) does not create an operational hazard, and
(iii) in the case of the audible signal, is identifiable by the operator despite ambient and machinery noise.
2 A load moment indicator system that is installed on a category 4 lifting appliance on a Canadian vessel that is not a restricted vessel shall
(a) give a clear and precise indication of the angles of heel and trim and of the reduced lifting capacity for those angles;
(b) be clearly visible so that an operator seated at the control position can easily read the indication during both day and night conditions;
(c) have an automatic emergency braking system that prevents freefall of the load without jolting in the event of overload; and
(d) have a manual control to bypass the automatic emergency braking system that is accessible to an operator seated at the control position and is protected against accidental operation.
