3.6. ATEX
The winches with EX coding can be used in ATEX zones 2 and 22. In addition, a distinction has been made in coding for the worm gear winches (WW), spur gear
winches (TL) and worm gear marine (MR) winches. See type plate for corresponding coding. The codes have the following meaning:
a.
CE marking in accordance with the European Machinery Directive
b.
Ex marking for explosion safety
c.
Group II for use in all environments (industrial use) except mining
d.
Category 3 is the level of protection and is suitable for either:
G (gas environments)
D (dust environments)
Followed by 'Ex' (explosion proof)
e.
Suitable for or:
II (Gas group II)
III (Dust group III)
Our marine (MR) winches have a higher ignition energy (IIB) in the gas group than our worm gear and spur gear (WW/TL) winches (IIC).
The ignition energies of the dust group are the same for all types of winches, namely IIIC.
f.
Temperature class for or:
T4 (temperature <135 ºC), T135 ºC (temperature <135 ºC)
T3 (temperature <200 ºC), T200 ºC (temperature <200 ºC)
Our worm gear and marine (WW/MR) winches are T4 marked. Our spur gear (TL) winches have a T3 marking.
g.
Equipment Protection Level:
Gc (gas) or Dc (dust)
h.
Ambient temperature (ambient) for use from -20ºC up to 70 ºC
4. Maintenance
The winch must be unloaded for inspection and maintenance tasks. Inspection and maintenance tasks must be performed by skilled personnel, e.g.
via your Gebuwin dealer.
Inspection/ Maintenance interval
Before each use
Per quarter
Annually
* Texaco 'Texclad premium 2' is recommended by us for the worm wheel gearing (or equivalent). Orders can be placed through your Gebuwin dealer or on the
website:
www.gebuwin.com.
5. Troubleshooting
Trouble/Malfunction
The unloaded winch rotates heavily
The load cannot be held
The load pressure brake does not function
6. Service
For servicing and/or servicing parts contact your nearest Gebuwin dealer. The exploded view diagram with regard to the servicing parts is available on our
website www.gebuwin.com. Orders for any necessary servicing parts can also be placed on the website.
Use original servicing parts only, correct functioning cannot otherwise be guaranteed!
7. Environment
At the end of the winch's lifespan, the various winch parts must be disposed of according to the current environmental regulations.
8. Guarantee
Gebuwin B.V. guarantees for a period of 2 years the materials and workmanship of the Gebuwin hand driven winches with the exception of the economy line
HW type winches. The HW type and all electrical winches and parts have a guaranty period of 1 year on materials and workmanship.
Tasks
-
visually check cable and loading hook
-
for WW type winches check amount of grease* on the worm wheel gearing
check the brake function
-
visually check cable and loading hook for any fracture
-
grease the worm - worm wheel gearing
-
-
check the load pressure brake for wear and tear
Replace the brake discs as needed
Be careful: Do not get any grease on the brake discs or preceding surfaces
check the cable according to DIN 15020 pg. 2 for wear and tear; also test and maintain the minimum breaking
-
force.
-
check the tightness of the mounting bolts
check all the winch parts for wear and tear; replace where necessary; grease where needed.
-
-
check the type identity sticker for clarity
Cause
no grease on the gearing
-
-
dirt on the gearing
during mounting the winch has pulled askew
-
-
the cable has been incorrectly wound round
the drum which means the crank turning
direction is incorrect
the brake discs are either worn down or faulty
-
-
braking mechanism and/or discs are jammed
due to infrequent use
Solution
apply grease
-
-
clean with a detergent and re-grease
-
level the mounting surface and re-mount the
winch
-
wind the cable correctly around the drum
check and/or renew the brake discs
-
-
loosen the brake by hitting the crank in the
correct turning direction with the flat of the hand
