Safety devices
-
A main brake acts on the engine in case of
power supply failure
-
An upper limit switch sensor stops lifting
when the spring touches the plate.
-
A lower limit switch sensor stops lowering
when the spring touches the plate.
-
An electrical emergency stop placed on
pendant control acts immediately and stops
the winch to the ascent and the descent.
-
Mechanical
locking
prohibiting
the
simultaneous action of the up and down
commands.
-
Electrical protection of the pendant control :
class 2.
-
Fuse protecting the command, in the electrical
box.
-
Hooks with safety latch.
The single-phase motor is protected against
excessive warm-ups by a probe inserted into the
coil. This probe prohibits operation by interrupting
the control circuit as long as the temperature of the
coil is not back to an acceptable value. In case of
intensive work or high duty, we suggest to allow a
15 minutes break every 45 minutes of work to avoid
overheating
(at 110V, break of 15’ every 15’)
.
2.3
Description of the work or control station
"Up" and "down" hoist movements are controlled
from the pendant control.
Never stand under the load.
In case of a command error, wait for a complete
stop of motion before performing another
command. The control buttons are held type
buttons.
Limit stops are not operating devices but safety
devices. They should therefore not be used
voluntarily but only serve as shutoff devices in case
of involuntary exceedance of the expected travel.
Never stay or work under load. If necessary, have a
barrier of security on the floor around the area at the
vertical of the load.
Avoid heavy slipping: Wait for a complete
stop of your installation before resuming
movement.
Check regularly that no obstacle is located along the
path of movement (above and below the load).
