5.2 Operating conditions
5.2.1 Operating environment
•
The operating environment must have the following specifications:
•
temperature: min. - 10°C; max.: + 40°C: relative humidity max. 80%.
•
use in an indoor environment: in this case the jib crane is not exposed to inclement weather and
does not require any special precautions.
•
use outdoors: the jib crane may be exposed to inclement weather during and after use. The electrical
parts of the hoist and trolley must be equipped with protection IP55, it is also recommended to protect
the hoist and trolley with overhangs and guards.
To prevent oxidation, protect the structure with adequate treatments and lubricate rotating parts.
Outdoor use of the jib crane is permitted if there is no exceptionally bad weather, which could modify
the values of the expected loads, for example heavy rain, heavy snowfall, strong wind, etc.
The crane in the standard model, must not be used in environments and areas:
•
With vapours, fumes or dusts which are highly corrosive and/or abrasive
(when this cannot be avoided intensify the maintenance cycles).
•
In the presence of flames and/or heat greater than the allowed temperatures.
•
With the risk of fire or explosion where the use of anti-explosion
and/or fireproof components is required.
•
In areas where strong electromagnetic fields are present which can generate
electrostatic load accumulations.
•
In direct contact with bulk food substances.
5.2.2 Danger zones and exposed persons
The danger zones are all of those where, in any operating phase, the exposed persons can be subject to
the risk that an event may occur hazardous for their safety, health of psychological/physical well-being.
Specifically, it is necessary to inform potentially exposed persons , that the operator assigned with use of
the jib crane does not always work, in the movement trajectories of the danger zones , with sufficient
visibility conditions to be able to completely and immediately prevent all potential risks of being crushed,
collisions and being dragged in in terms of any people who thus must avoid to exposing themselves to risk
during the manoeuvres in these areas.
It is mandatory for the customer to place adequate signs in the danger zones to
prohibit or limit access to unauthorised and/or unassigned personnel in the areas
where the jib crane works, as required by current laws
5.2.3 Work area lighting
The GRL series jib cranes are not equipped with their own lighting system. Consequently, the workplace of
the operator assigned to use the crane must be adequately lighted and ensure maximum visibility.
The level of ambient light must always be such as to ensure the
maximum possible safety for crane operations.
It is mandatory to install supplementary lighting systems in areas that are
not sufficiently lit, thus preventing shadow areas that inhibit or reduce the
visibility in the operating and/or surrounding areas
