•
When the electric movements of the crane are controlled by remote control the
pushbutton panel is not restricted by the crane, the operator thus must always
pay utmost attention during manoeuvres without ever losing sight of the work
area and the handled load in order not to compromise his safety and/or that of
any exposed persons.
•
It is prohibited to control the jib crane movements while on board it.
5.1.2 Permitted loads, unpermitted loads
The loads must be:
•
Of a shape, dimensions, weight, equilibration and temperature suitable for the characteristics where
they need to be handled and must be compatible with the performance of the jib crane.
•
Equipped with grip points and/or slung with specific accessories which prevent accidental dropping
•
Stable and not subject to changing their static or physical configuration during handling.
Handling the following loads is not allowed:
•
whose weight, including any accessories, exceeds the crane capacity-
•
with weights that are unbalanced compared to their centre of gravity.
•
with surfaces that are not sufficiently resistant to the pressure exercised by the
grip
•
that, due to their chemical and physical characteristics, have been classified as
hazardous, for example: flammable, explosive, radioactive, etc. materials
•
toxic or handful materials or products, if not handled in specific safe containers,
for example; corrosive chemical products, with biological risks, etc.
•
bulk food products or substances that can come into direct contact with the hoist
parts or with its lubricants.
•

barycentre during handling

Lifting accessories that are placed between the load and the lifting hook, such as: balances, pliers,
suction cups, magnets and electromagnets, etc.
•
The use of such accessories must be in compliance with the instructions supplied by their
manufacturers.
The following accessories are generally not allowed:
•
with functional specifications that can cause dynamic overstress to the
crane greater than those allowed or accidental overloading.
•
that can collide with the parts of the jib crane.
•
that limit the free movement of the load.
•
that are connected with independent electrical lines.
The weight of the lifting accessories must be subtracted from the rated capacity of the
jib crane.
