RISK ASSESSMENT
QPP147 Section 2 Rev. March 07
B5. Operating the crane by reaching
in through the door or window.
(The operator is not in full
control of the crane and could
cause the crane to collide with
people, buildings and other
objects).
B5. Only operate the crane while seated in the operator’s seat.
B6. Dropping of the load from an
unattended crane.
B6. Never leave a suspended load on an unattended crane. When leaving the crane, always lower
the load to the ground, switch off the engine, lock the crane and take the keys with you.
B7. Dropping of load, damage or tip
over of the crane due to
overloading or unstable load.
B7. Carry out the following checks before lifting a load.
• Check that the total weight of the load (including the weight of slings, hook and
attachments) is below the rated capacity of the crane?
• Check that the number of parts of line on the main winding wire rope is a standard number
according to the rated lifting capacity?
• Check that the slings are properly positioned to lift the load above its center of gravity?
• Check that the main winding wire rope is hanging vertically?
When the load just leaves the ground pause until it stops swinging. Confirm that the load is
stable before continuing to hoist.
B8. Dropping of load from insecure
slings or hook.
B8. To prevent the load from falling off or slipping out of the slings, pay attention to the following
points when arranging the sling.
• The slings or chains should be of the right capacity and in good condition.
• Arrange the slings so that they do not get tangled with each other.
• The hook is fitted with a retainer to prevent the slings from slipping out. Check that the
hook is in good condition and the retainer is operating correctly.
• Place a protector (some soft material) to prevent the rope from damage where it comes into
contact with the corner of the load, and elsewhere where the sling is prone to damage.
