3.5.1 Control devices
The control of the DRH wire rope hoist and related trolley is generally carried out with a
push- button panel
(being
part or not of the supply) which sends electric signals to a low voltage
control panel
to activate the related
movements.
These movements are activated by means of the following buttons on the push-button panel (fig 7):
•
ascent
and
descent
buttons to control the
lifting of the hoist
(fast and/or slow)
•
right
and
left
buttons to control the transit of the
trolley
(fast and/or slow).
The buttons for the functions
ascent
and
right
have a
black symbol on a white background
, while those for
descent
and
left
have a
white symbol on a black background
. They start the function when they are kept pressed
down and the controls of the auxiliary slow speeds, of lifting and of transit, can be activated with
separate buttons
or with two pushes, the first push for the command of the “slow” speed, the second push to command the “fast”
one. To allow the functioning of the hoist it is necessary to bring the button for the emergency stop, located on the
push-button panel, to a raised position for the gearing and then push the function button.
When the hoist is provided with a control panel, the push-button panel is of the pendant type and manoeuvrable by
the operator from the ground.
The hoist can be controlled also by remote control, the functionality of the buttons is unvaried with respect to that
of the push-button panel in pendant execution.
The control of the hoist can be carried out also with a fixed push-button panel (e.g. automatic cycles). In this case,
the installer must check that the control ensures the maximum possible safety with particular attention to the
visibility of the load.
The electric wire rope hoist and related trolley, according to contractual agreements, can be supplied
complete with
or without control devices and systems
(control panel with push-button panel).
3.5
Safety measures and instructions
When the wire rope hoist is supplied without control devices or systems, it is forbidden to
put it into service before it has been completed in conformity with the rules of the
Machines Directive 2006/42/CE.
