Wind speeds can be variable throughout the working day. What action must be taken to ensure safe working conditions are maintained?

Answer 13

Wind speed must be constantly monitored.

Question 14

How does the deflection of the boom or jib affect the lift?

Answer 14

the jib deflection can cause an increase in the radius.

Question 15

if checking the oil level using a dipstick, why must gloves be worn?

Answer 15

They can prevent skin diseases and prevent contamination of oil onto the operating controls and cab.

Question 16

What is the main purpose of the Rated capacity indicator (RCI)?

Answer 16

A device that automatically provides the operator, within a specified tolerance, warnings that the load is both approaching rated capacity and has exceeded the rated capacity.

Question 17

Give Four reasons that may cause the crane to overturn.

Answer 17

Excessive load swing, soft ground, working on slopes, excessive loads, insufficient outrigger support, insufficient counterweight.

Question 18

Why must the seat belt be worn, even with with the cab door closed?

Answer 18

In the event of a roll over. It keeps the operator within the confines of the operating seat, which may minimise injury by not being flung around.

Question 19

Crane operations fall within the scope of the lifting Operations and lifting equipment regulations (LOLER) 1998. name two requirements of the regulations with regards to lifting.

Answer 19

Lifts must be properly planned and properly supervised

Question 20

What effect can a swinging load have on a crane?

Answer 20

It can cause and increase in radius and create instability.

Question 21

What are the three actions or stages that a crane operator undertakes during pre-use inspections?

Answer 21

Carry out checks according to manufacturers requirements, Record when checks have been performed and report all defects immediately.

Question 22

Before leaving the cab for a rest break, after parking and switching off the machine. What final action must be carried out?

Answer 22

The machine must be isolated to prevent unauthorised individuals from starting/moving or operating the machine

Question 23

In what situation does a hard hat not need to be worn when operating a mobile crane

Answer 23

only when sitting in a enclosed cab that meets the FOPS criteria

Question 24

during work, the engine starts to overheat Explain the danger if someone tries to remove the radiator or expansion tank cap.

Answer 24

the cooling system is normally pressurised and removing the the cap can allow hot water to escape uncontrollably with the potential for causing severe burns

Question 25

if the words stop now are given to the crane operator by the radio during the lift what action must the operator take?

Answer 25

stop immediately

Question 26

when working in a confined area or space:
a) what danger can be present with regards to the counterweight of the machine
b)when should measures be taken
c)what measures should be implemented

Answer 26

a)The gap between the counterweight and a structure being reduced or contacting the object/structure when slewing

b)When the gap will be less then 600mm

c)ensure sufficient clearance and block of access routes

Question 26

if a load is being slewed to fast for its size, what two factors must the operator and signaller take into account

Answer 26

the length of time or distance needed to stop the slew and the expected load swing

Question 27

Name three ways in which wind speed can affect the lifting operations

Answer 27

it causes load swing, can slow or increase the slew speed of the crane, and can shut down lifting operations.

Question 28

a)who can authorise partial outrigger extensions

b)what is the effect on lifting capacity by partially extending the outriggers?

Answer 28

N/A

Answer 29

N/A

Question 30
