NCCCO TEST (ACTUAL 2025) QUESTIONS WITH
CORRECT VERIFIED ANSWERS
Articulating boom loader and fork assembly: safety
precautions *TQ
1. test the fork control functions prior to use improper rotation
or accidental opening of form tines may cause the loss of a
load
2. to maintain stability, keep the load as close to the ground
and as short a radius as practical
3. during transport, the fork assembly must be stowed and
secured on the vehicle on such a manner that it cannon swing
out
4. overloading the fork assembly could cause the form
assembly to open uncontrollably
5. when handling drywall, close the fork as soon as the los
clears the truck bed or ground surface
6. the transport of persons is prohibited using a fork assembly
attachment under any conditions- no riders on forks or load
7. when practical, the load should be clamped between tines
and backrest of the fork assembly
8. the tine locking devices shall be in the locked position for
all lifts load shift or load loss
9. the fork assembly should not be moved manually to engage
the load
,10. the operator shall always present the load in a manner that
ensures a safe loading environment
load charts: general precautions *TQ
1. load charts must be posted on the crane so that they are
visible when the operator is at the control station
2. if a crane is equipped with a remote control, the load charts
must be at a level visible to the operator from the ground
3. load charts must be maintained so they remain legible;
never operate a crane without a legible load chart
Types of loading charts
Articulating crane typically comes with one or two types of
loading charts. The first and simplest one dimensional load
chart; the second less common variety is a two-dimensional
load chart.
Two-dimensional load chart
Show both the vertical and the horizontal ranges of the booms
lifting capability. This type of chart gives the operators a
reference as to the cranes capabilifss when the cranes hook
point moves in the vertical direction as well as horizontally
, Capacity lines/curves
Show what loads can be lifted by the cranes at different
horizontal and vertical reaches.
Reading loading charts
1. Load rating charts are specific to every make and model of
crane. Some cranes are equippeted with multiple load charts
for various operating conditions. If your chart you are using
does not match the specific crane you are using notify your
supervisor and do not use the crane
2. On some load charts the angle of the inner boom is also
stated to indicate what position the boom must be at for the
capacities to be valid
3. Interpolation is the technique of estimating what the cranes
gross capacity is between two stated values on the load chart.
Never interpolate when reading and interpreting load charts
always use the next lower capacity
Charts representing stabalizee deployment
Charts may reflect "stabilizers fully extended" (best position
for max. Stability and rating or "stabilizers mid span"
(position reflects)
