5. - OPERATION
5.1 – Functions on “DGT” endcarriages and beams
5.1.1 Intended and proper usage
•
The
drive
Units
, comprising
“DGT” series Wheel Groups
in combination with
“DGP”
series Offset
Gearmotors
and
“DGT” endcarriages
equipped with drive units, are designed for handling operations on rails
set onto lifting equipment, such as, for example, bridge cranes, trolley and wall mounted cranes, etc. and/or
related travelling trolleys, guaranteeing accurate alignments for handling structures, control over high operating
speeds, and easy installation and maintenance.
•
“DGT” series Wheel Groups
and
“DGP”
series Offset Gearmotors
,
comprising the
drive units
are modular
components specifically designed for
endcarriages
on
industrially designed
bridge cranes
.
•
Forward and reverse running movements
must be activated electrically
.
5.1.2 Admissible and inadmissible loads
•
Loads must be
compatible with performance specifications for
“DGT” drive units and endcarriages:
in terms
of shape, dimensions, weight, balance and temperature.
The handling of the following types of loads is not admissible:
•
weight exceeding the capacities of “DGT” drive units and endcarriages
•
chemical-physical specifications classifies loads as dangerous (e.g. inflammable, explosive,
radioactive materials, etc.)
•
loosely packed food products or substances, which can come into direct contact with parts
on the “DGT”
drive units and endcarriages or their lubricants
•
loads whose static and/or chemical-physical configuration or balance can be altered during
handling operations
5.2 – Operating conditions
5.2.1 Operating environment
•
The operating environment must present the following specifications:
•
temperature:
min. -10°C; max. +40°C;
relative humidity:
max. 80%;
maximum altitude:
1000 m a.s.l.
•
indoor environment:
“DGT” drive units and endcarriages
not exposed to atmospheric agents do not
require particular precautionary measures.
•
outdoor environment:
“DGT” drive units and endcarriages
can be exposed to atmospheric agents during
and after operation. Electrical parts are classified as minimum protection IP55; however, it is advisable to
protect the motors with a roof covering or protective guard.
To avoid the formation of rust, protect the frames with suitable rust-proofing treatments and keep all
mechanisms well lubricated.
Standard series “DGT” drive units and endcarriages must not be operated in environments and
areas presenting the following characteristics:
•
Vapours, fumes or highly corrosive and/or abrasive dust particles
(when such conditions
cannot be avoided, intensify maintenance care)
.
•
Flames and/or heat exceeding admissible temperatures.
•
Fire or explosion hazards, and where the use of anti-explosive and/or spark-proof
components is required.
•
Areas presenting strong electromagnetic fields, which can generate accumulations of
electrostatic loads.
•
Direct contact with loosely packed food substances.
