2.2 Technical information and service conditions
2.2.1 Regulatory reference framework
In the designing and construction of the manually rotated jib cranes, the following standards and main
technical rules have been taken into consideration:
•
EN ISO 12100:2010 “General principles for design”
•
EN ISO 13849-
1:2008 “Safety-related parts of control systems” (where required).
•
EN 6020432:2009 “Safety of machinery. Electrical equipment of machines. Requirements for
hoisting machines”
•
EN
– 60529/97 “IP code”
•
ISO 4301-
1/88 “Cranes and lifting appliances --. Classification”
•
FEM 1.001/98 “Rules for the design of hoisting appliances”
•
FEM 9.683/95 “Selection of lifting and travel motors”
•
FEM 9.755/93 “Measure for achieving safe working periods for motorised serial hoist units
(S.W.P.)””
•
FEM 9.941/95 “Graphical symbols for control devices”
•
EN 16851/16 “Cranes – Light crane systems”
2.2.2 Protection and insulation of electrical parts
•
Rotation motor: Protection IP55 (motor) IP23 (brake); insulation class “F”
•
Electrical panel: Protection IP55 - Maximum voltage insulation 1500V
•
Push-button panel: Protection IP65 - Maximum voltage insulation 600V
•
Collector: Protection IP00 (IP55 upon request) - Maximum voltage insulation 500V
•
Limit switch: Protection IP65 - Maximum voltage insulation 300V
•
Cables: CEI 20/22 II - Maximum power insulation 450/750V
2.2.3 Electrical supply
•
The jib cranes have been designed to be powered with alternating electric current with
maximum three phase voltage of 480V- Standard GRL gear motor with three phase inverter.
2.2.4 Ambient use conditions
•
Operating temperature: minimum - 10°C; m 40°C
•
Maximum relative humidity: 80%
•
The machine must be installed in a well ventilated area, free from corrosive fumes (acid fumes, salt
mist, etc.).
•
It is forbidden to use the machine in an explosive atmosphere or potentially
explosive one or where the use of non-explosive components is required
•
Sufficient work spaces must be provided in order to ensure the safety of the
operator and personnel assigned to maintenance.
2.2.5 Noise - Vibration
•
For both manual and electrical rotation jib cranes, noise level during functioning is below the
prescribed limits adopted (70 dBA).
•
The vibrations produced by the jib crane, during arm rotation, are practically zero and are not
hazardous for the health of the personnel who operates it.
•
Excessive noise or vibration may be caused by a fault which must be immediately reported and
eliminated in order not to compromise the reliability of the job crane.
