Control Measures
Pre-start Checks.
Plant to stick to designated roadways and
turning areas.
Personnel on hand to warn others of crane
movement in the vicinity or via radio where
available.
Alternate pathway defined by bollards and
reflective tape.
Sufficiently skilled employees to complete
task (competencies and Licences)
Adequate consultation with all relevant
employees
Adequate competent supervision
throughout the project
Proper planning for equipment required for
the task
Site & work area inductions compulsory for
all personnel
Desired setup area should also be level,
unless prior consultation has been made
with the supplier of the crane
The workplace is adequately prepared for
the incoming mobile crane, including where
possible a clear predefined area/crane pad
for the crane to position upon
Check and confirm exclusion areas Barricades, witches Hats, Danger Tape,
Warning Signs

Inspect chains and or
slings, shackles, hooks,
and attachment points in
preparation for use
1) Crane overturning due to
unstable ground condition
2) Personnel being crushed by
outriggers
5) Access roads are available and soundly
constructed with suitable entry points to
site
6) Crew should always inspect site prior to
positioning crane in final position
7) Elements to observe include
8) Load location and scope of lift
9) Location of any overhead obstructions
including wires, trees, buildings, restricted
airspace (i.e., near airport)
10) Location of any underground services
and/or trenches including utilities and
drainage arrangements that may affect
integrity of ground
11) Adequate room for rigging and erection of
mobile crane
12) Adequate tail (counterweight/winch) swing
clearance
13) Ability to cordon off area with suitable
barricading resources
1) Outriggers must be positioned on a flat
surface.
2) Using timbers or suitable material for pads
to evenly distribute the load to the ground.
3) Crane to be located within the radius for
the loads being Lifted.
4) Outriggers should only be extended on the
side where the Operator is positioned or
with a suitable spotter.
5) Where space permits, outriggers shall
always be fully extended.
6) Where space is limited, crane should be
configured to maximum capacity – this may

require the use of reduced outriggers or on
rubber, when permitted by the
manufacturer.
Outriggers shall always be extended to
manufacturers procedures and
specifications, including the requirement to
fit manual pins.
All outriggers-jacks should be always
utilized.
Generally Standard Safe Working Load
capacity charts are based on all outriggers
fully extended and set with wheels clear of
ground.
Outrigger Packing
Additional packing should always be utilized
under outrigger floats
Commonly used Outrigger Mats should
carry designn information and be subject to
periodic inspection
When timber packing is utilized, it should
be in a ‘pigsty ‘packing
Arrangement ‘Rule of Thumb’ formulae and
calculations should be observed.

Cm = Total mass of crane (KN)
L = Total mass of load (KN)

truck in an easily
accessible spot for the
crane to load its
counterweights
Changes in weather conditions
 Changes in operators
 Changes in ground suitability

Packing up and/or
leaving crane onsite.
Unauthorised person access crane site
 Damage to crane
 Injury to public
2) Use an EWP or ladder for this task & follow
safe work practices
1) Continual safe operation can be aided by
periodic inspection throughout the project
of the following.
2) Outrigger Jacks – Leaking oil/retraction of
shaft
3) Outrigger Mats – excessive settlement
and/or sinking into ground, i.e., loadings
increasing beyond estimated capacity of
ground – such as unknown backfilling
4) Outrigger Floats – Cracking or critical
damage
5) Evidence of water content in ground
6) Should requirements change during
operation, then crew shall re-assess and
review crane capacity and wider
environment to ensure revised work
practice is within limits and safe to continue
operation.
1) Upon completion of project, or specific
stage the crane
2) equipment and site shall be left in a secure
and safe manner
3) If the crane is to be left onsite
4) Retract Boom, remove keys from the
ignition and secure/lock
5) Outriggers should be inspected prior to
next use
6) Barricading should remain in place around
the crane and any work area deemed
necessary
