5. TESTING
- Warning! Testing must be carried out by qualified
personnel. Take all necessary precautions to ensure perso-
nal safety.
- Warning! The winch must be tested before use.
Before testing the hoist make sure that it has been correctly
installed.
1) Extend the jib to its maximum and lock into position. Using the
down botton lower the hook (without load) to the bottom of the
hoistway and make sure that it is clear of obstructions and at least
three turns of rope remain on the drum.
2) No-load test. Load the hoist with 20 Kg and check the correct
operation of the hoist by raising and lowering the load through its
entire run once (checking the correct operation of up and down
bottons, stop button, UP limit switch operation and the correct
winding of the rope on the drum. Check the operation of the brake.
3) Load test. Load the hoist with its maximum admissible load
(200 Kg). Lift and lower the hoist through its entire run to test the
support structures and brake.
Following the test, check the security of the mountings and
supports. Check again the horizontal alignment of the hoist with a
spirit level.
4) The hoist is fitted with a safety which stops travel at the UP (9)
and fully unwound positions (16) to avoid the rope winding on in
the wrong direction.
Do not depend on this safety to stop the winch; release the control
button to stop the winch instead.
IMPORTANT!! Down limit switch (16) activation can
occur either due to incorrect working height or due to other
problems which may prejudice correct hoist functioning. After
the limit switch has been activated, the hoist installation and
components must be checked (rope, drum, shaft etc.)
If satisfied with the test results complete the entry in the site register
(Tab. 2).
In case of new installations and after every service,
repeat the no-load (2) and load (3) tests described above.
6. SAFETY WARNINGS AND OPERATING PRECAUTIONS
1) Do not lift weights in excess of the maximum
admissible load.
2) Do not allow anyone to stand under a load.
3) Never attemps to lift loads attached to the ground
(e.g. embedded poles, plinths, ect.).
4) Make sure that the load is always well secured to
the hook and close the safety catch (Fig. 4.1 ref. 6).
5) If accessories are required for lifting, ensure that
they are certified and approved (belts, ropes, slings etc.).
Subtract the weight of accessories from the maximum load
capacity.
6) Ensure that no load spillage occurs during lif-
ting.
7) Ensure complete load stability before unhooking
the load.
8) Never unload a suspended load with accessories
that cause immediate release and never cut slings to remove
the load.
9) Keep hands and other parts of the body well clear
of the drum during operation to avoid getting caught in the
winding rope and seriously injured.
10) Keep hands and other parts of the body well
clear of the counterweight during lifting to avoid crushing
against the stop lever.
11) Do not use the machine in bad weather (strong
wind or storms) as the load is not guided.
12) The entire lifting run and the load itself
must be visible from the operating position and
adequately illuminated.
13) Ensure that all the guards are in place.
14) Check that the rope winds on correctly, one turn
at a time without slack or overlay which might damage the
rope itself. If it is not correctly wound on, unwind the rope
and rewind it correctly under tension.
15) Make sure that lifting run is free from obstacles,
and be sure that nobody can lean forward on intermediate
floors.
16) Enclose ground loading area to prevent people
from interfering with work.
17) Do not allow children access to the hoist.
18) When the hoist is not being used, do not allow
unauthorised persons access to it.
19) The hoist may not be used for pulling loads
obliquely (exceeding 5° with respect to vertical lifting).
20) Do not pull on the pendant control to turn the
hoist; use the frame for this purpose, turning it by hand.
21) Do not leave a suspended load unattended. Lift
it or lower it and off load it.
22) When lifting or lowering a load use a smooth
action to minimise dangerous vertical or sideways
movements of the load.
23) Do not allow loads to spin while lifting or
lowering. The cable could be dameged.
24) With 25m or 30m low voltage pendant:
fasten the cable to the structure,otherwise it could bre-
a k .
25) Lower and stop the hoist, remove the load, wind
the rope completely onto the drum and then unplug before
leaving the hoist unattended.
When operation is resumed after a lengthy period of disuse the
entire machine must be tested under no-load conditions before
starting, as described above (point 2, CAP.5).
7. TESTING AND MAINTENANCE
Warning!! Only carry out maintenance with the
machine switched off, unloaded and disconnected from the
mains.
- Repairs must be done by qualified personnel or by IMER Technical
Service.
- Use only IMER original spare parts.
- Check the motor brake every 6/7 days.
- Ensure that the notices and inscriptions on the
machine are prominently displayed and legible.
- Keep the machine clean of dirt.
- Check the operation of the UP and DOWN position
limit switches at the start of each work shift.
- Check the electrical cable at the start of every work
cycle for accidental damage.
