2. – DESCRIPTION OF COMPONENTS AND TECHNICAL SPECIFICATIONS
2.1 “DGT” series endcarriages for cranes
2.1.1 Intended and proper usage
•
The
drive
units for cranes comprise “DGT” series wheel groups in combination with “DGP” series offset
geared motors
, are built specifically for handling lifting systems on rails, such as, for example, travelling cranes,
trolley cranes, wall-mounted cranes, etc. and/or related running trolleys, guaranteeing the precise alignment for
moving structures, control over high shifting speeds, while facilitating installation and maintenance.
•
“DGT” series wheel groups and “DGP” series offset geared motors
are modular components specifically
designed for
drive
units for cranes
by manufacturers of machinery and industrial lifting and handling
installations.
•
Running movements (forward and reverse)
must be enabled electrically
.
2.1.2 The range of Drive Units
•
These
drive
units for cranes
are designed and engineered based on the principle of modular components
which, in addition to the more common versions commercially available, when assembled to one other in relation
to the user’s requirements, allow for the fast and economical realization of multiple standard and special
configurations.
•
DONATI drive
units
are configured in
6 production sizes
, for which the basic components are:
•
6 sizes of
“DGT” series wheel groups
(Ø 125, Ø 160, Ø 200, Ø 250, Ø 315 and Ø 400/400R)
•
4 sizes of
“DGP” series offset geared motors
(DGP 0, DGP 1, DGP 2 and DGP 3)
•
4 sizes of
self-braking
motors
(motor 71, motor 80, motor 100 and motor 112)
Wheel Group configurations based on combinations between “DGT” Wheels and “DGP” Motoreducers
•
The
6 production sizes for “DGT”
series Wheel Groups
cover the following operating limitations:
•
Capacity
of the lifting and/or traversing equipment:
•
from
1000 to 40,000 kg
•
Running
speed
:
•
single speed, from
3.2
to
25 m/min
;
•
two-speed, from
12.5/3.2
to
80/20 m/min
.
•
The modular design of the basic components (wheels, reducers and motor) allows for two configurations of
“DGT”
series drive units
:
•
Idle drive units
(fig. 1a)
•
Motor driven units
(fig. 1b)
•
The flexibility of the numerous fastening solutions adopted allow for assembly on a variety of mechanical frame
types, as well as easy integration with a number of accessories available on the market, such as, for example,
guide systems, or collision proof systems, whether mechanical, electrical or electronic, or speed control and
crane and trolley stop position systems.
