5.2.5 Load bearing capacities on “DGT” drive units and beams
•
The maximum load bearing capacity
on
“DGT” drive units and endcarriages
, in the operation configuration
foreseen, is defined by the values for
maximum reaction R max
. (kg) and
Average Reaction R ave
. (kg),
admissible for the wheels.
Never exceed the maximum load bearing capacity
on
“DGT” drive units and endcarriages.
5.2.6 Drive operations
•
As a rule, perform one movement at a time, since this is the only way a manoeuvre can be started, stopped and
kept constantly under watch by the operator, who must avoid continuous and repeated jog type movements,
even in the case of small shiftings.
•
Limit switches are set so as to operate in proximity to the extremities of runs. Avoid travelling manoeuvres with
short and repeated jog type movements or sudden inversions of course, which, in addition to casuing damage to
mechanical parts, can also generate dangerous load oscillations, with risks of collisions or violent impacts
between the
“DGT” drive units
or
endcarriages
and the endstroke mechanical stops.
•
Operate with attention and diligence, keeping a constant watch on manoeuvres, and visually
controlling the balancing of loads being handled.
•
Avoid sudden manoeuvres and “jolts," which are damaging to the reliability of the drive
motors, as well as to the load’s stability, due to dynamic effects generated by such
movements
5.2.7 Safety devices
•
A power failure will cause the driving movement to stop in the shortest possible time and space, since the
electrical motors are equipped with automatic braking devices. However, the adjustment of the braking torque on
the motors must be such as to prevent generating sudden braking, which can result in the dangerous tilting of
handled loads.
•
The limit switch demarcate the maximum horizontal travel of the
“DGT” drive units
or
endcarriages
. They are
emergency devices and are not suitable as operating stops or acknowledgement devices for subsequent
operations.
When excluded from the
DONATI SOLLEVAMENTI S.r.l.
, shipment, the electrical limit switch
devices must mandatorily be installed by the Buyer.
