Category 1 Operational Aids
If a Category 1 operational aid is not working properly, it must
be repaired no later than 7 calendar days after the deficiency
occurs.
Exception: If the crane user documents that he/she has
ordered the necessary parts within 7 calendar days of the
occurrence of the deficiency, the repair must be completed
within 7 calendar days of receiving the parts.
1.
Boom or Luffing Jib Angle Limiter
(automatic boom or jib stop)
Temporary alternative measures if inoperative or
malfunctioning:
The qualified person directing the lift shall make sure the
maximum boom or jib angle/radius specified in the
Capacity Chart for the load being handled is not
exceeded. One or more of the following methods must
be used:
a.
Measure radius using a tape measure.
b.
Measure the boom angle with a protractor-level on
the centerline of boom.
c.
Clearly mark the boom or luffing hoist cable (so it
can easily be seen by the operator) at a point that
gives the operator sufficient time to stop the boom
or jib within the minimum allowable radius.
In addition, install mirrors or remote video cameras
and displays if necessary for the operator to see the
mark.
d.
Clearly mark the boom or luffing hoist cable (so it
can easily be seen by a designated signal person)
at a point that gives the signal person sufficient time
to signal the operator and have the operator stop
the boom or jib within the minimum allowable radius.
2.
Anti-Two-Block Device
Temporary alternative measures if inoperative or
malfunctioning:
The qualified person directing the lift shall establish
procedures to furnish equivalent protection. One or
more of the following methods must be used:
a.
Assign a signal person to signal the operator to stop
hoisting when the load is a safe distance from the
boom or jib point.
b.
Clearly mark the hoist cable (so it can easily be
seen by the operator) at a point that will give the
operator sufficient time to stop the load a safe
distance from the boom or jib point.

Category 2 Operational Aids
If a Category 2 operational aid is not working properly, it must
be repaired no later than 30 calendar days after the
deficiency occurs. Exception: If the employer documents that
it has ordered the necessary parts within 7 calendar days of
the occurrence of the deficiency, and the part is not received
in time to complete the repair in 30 calendar days, the repair
must be completed within 7 calendar days of receiving the
parts.
1.
Rated Capacity Indicator/Limiter
Temporary alternative measures if inoperative or
malfunctioning:
The qualified person directing the lift shall establish
procedures for determining load weights and shall make
sure that the weight of the load does not exceed the
crane’s rating at the radius where the load is handled.
The weight of the load must be provided to the operator
before the lift is made.
2.
Boom Angle or Radius Indicator
Temporary alternative measures if inoperative or
malfunctioning:
a.
Refer to the pendulum boom angle indictor on the
boom butt (viewable from operator’s cab).
b.
Measure the boom angle with a protractor-level on
the centerline of boom.
c.
Measure radius using a tape measure.
3.
Jib Angle or Radius Indicator
Temporary alternative measures if inoperative or
malfunctioning. Use either or both:
a.
First, make sure you know the boom angle (see item
2 above).
b.
Then, measure radius using a tape measure.
4.
Drum Rotation Indicator
Temporary alternative measures if inoperative or
malfunctioning:
Mark the drum to indicate its rotation.
If the operator cannot see the drum, add mirrors or
remote video cameras and displays so the operator can
see the mark.
