6.5 Disassembling the “DGP” offset gearmotor
Disassembly operations must be carried out by qualified and trained personnel, and
when working above ground level, equipped with:
•
suitable individual protection devices (e.g. safety harnesses, etc.);
•
appropriate working tools (e.g. fork lift, crane, scaffolding, etc.).
after carefully evaluating the following parameters:
•
type of working environment, ambient specifications and type of flooring
•
height of the installation with respect to the flooring and available spaces
•
dimensions and weight of the “DGP” offset gearmotor to disassemble
The “DGP” offset gearmotor being disassembled must be moved SOLELY using LIFTING
EQUIPMENT
(crane, hoist, etc.)
and
a suitable harness
(textile fabric sling)
fastened loop- like
onto the connection area between the motor and swinging reducer
(fig. 25)
.
Disassembling the “DGP” offset gearmotor
(fig. 26)
:
1. Cut off power to the
“DGT” drive units
or
endcarriages
;
2. Sling the offset gearmotor
(1), using a textile fabric sling
(2),
fastened loop-like onto the motor (fig. 25) without,
however, tensioning the harness;
3. Unfasten the screw and nut (3), and remove it from the reaction arm (4) on the operating head (5);
4. Remove from the gearmotor (1) the screw and nut (3) and shock absorber group, comprising two buffers (6) and
two pressure rings (7);
5. Completely extract the gearmotor (1), integral with the drive shaft (8), from the wheel (9), maintaining it
suspended from the lifting equipment with the harness (2);
6. Set the gearmotor (1) on the ground, operating the lifting equipment.

To reassemble the “DGP” offset gearmotor once more onto the operating head, proceed by
following the above steps in reverse sequence, i.e. as outlined in the procedure at page 50.
