To shut down the hoist at the end of work it is necessary to:
Normal stopping:
• Normal stopping of the controlled functions simply requires the relevant buttons to be released, which, by
returning to the “0” position, stops all corresponding movements. They are instantly blocked and kept in a stable,
safe state by the brakes of the motors.
Emergency stopping:
• The emergency stop must be used only when danger conditions occur, which require the hoist to be immediately and
completely stopped.
Putting the machine back into operation after an emergency stop:
Stopping and shutting down the hoist at the end of work:
1. Remove the problems which caused the emergency stop.
2. Unlock the “emergency stop” button by returning it to the forward position.
3. Repeat the procedure described in points 6 and 7 in paragraph 5.3 “Setting up - Starting the hoist”.
1. Set down the load in the decided place. Never leave the load suspended (fig. 114)
2. Free the lifting hook of any slinging used to move the load.
3. Position the hoist/trolley in the defined parking area for inoperative periods.
4. Lift the hook to a height of no less than 2.5 m so that it does not obstruct or create danger for people or things
below the hoist (fig. 115).
5. Stop movements of the hoist by pushing the red mushroom-shaped “emergency stop” button right in.
6. Place the push-button panel out of the way so it does not constitute an obstruction.
7. Remove the voltage by turning off the line disconnecting switch – place the lever in the “0” or “OFF” position.

Stopping the hoist – Switching off at the end of use
• If there are serious or unknown anomalies, stop the machine immediately by pushing
the red mushroom-shaped emergency stop button located on the control panel and
wait for the intervention of the technician responsible for the machine.
• Do not use the emergency stop button for normal stopping of the controlled functions.
In order to put the machine back into operation, after an emergency stop, it is necessary
to:

• ALWAYS follow the directions and instructions in the use and maintenance manual and check the integrity of the
components and parts of the hoist.
• ALWAYS ensure that the hoist operates in an environment protected from atmospheric agents (rain, wind, snow,
etc.), or, if in the open, that it has adequate shelter or protection (fig. 116).
• ALWAYS check that the capabilities of the hoist correspond with the job which needs to be done (work cycles –
intermittence – duration of use – load to be moved) - (fig. 117).
• ALWAYS check the suitability of the structures which support the hoist and trolley (fig. 118).
• ALWAYS verify that the running girder is placed at a height which ensures that the operator cannot interfere with
the body of the hoist. If this is not possible then appropriate shields or signs must be provided in the danger zone
(fig. 119).
• ALWAYS verify, before performing the manoeuvre, that the area in which the trolley runs is free of obstacles.
• ALWAYS check that the level of maintenance of the hoist (cleanliness, lubrication) and its main components (ropes,
hook, push-button panel, etc.) is acceptable.
• ALWAYS verify the suitability and functioning of the electrical wiring; in particular, check that the motors are
functioning properly.
•
ALWAYS
verify correct response of the movements of the hoist and trolley.
• ALWAYS test the functioning of the “emergency stop” button.

Criteria and precautions of use
• The correct use of the DRH electric rope hoists and of the relative trolleys guarantees
the safe and full performance of the machine.
• These potentialities are only guaranteed if the following instructions are strictly
adhered to:
fig. 116 fig. 117
