RISK ASSESSMENT
QPP147 Section 2 Rev. March 07
E. HAZARDS WHEN
EXTENDING AND
RETRACTING THE BOOM
RISK CONTROLS & GENERAL PRECAUTIONS
E1. Automatic stop from over-hoisted
condition. (AT-15 Euro & MAC-
25 only).
E1. Lower the hook sufficiently before you lower the boom. Lowering the boom can put the winch into an
over-hoisted condition, which causes an automatic stop.
E2. Damage to the boom if used to
push or pull objects. (Not
applicable to DM type Franna).
E2. Do not use the boom to push or pull objects - the crane is not designed for this. If the top of the boom
is used to push cargo along a truck bed or push objects around the construction site it will get damaged.
If objects are pushed or pulled by slewing the boom, the boom will bend. To move objects, hoist them
clear of the surface even if this is time consuming. Alternatively use a forklift or another suitable
lifting/hauling machine.
