Re-assembly
•
Re-assemble the parts in the order shown in parts drawing�
Inspection and maintenance
•
Damaged parts (twisted, cut, worn, broken etc) must be
replaced before the hoist can be used again�
•
Follow the dismantling procedures� Check for damage to the
chain, hook, end ring, bolts etc� Check for damage on the
handle, brake cover, handle-ratchet, brake discs and brake
pawl�
•
When dismantling the hand wheel and ratchet unit, check
the gear, drive axle, chain guide, side plates and upper
hook�
•
Always clean all parts carefully with cleaning oil or a similar
cleaner before the hoist is re-assembled� Smear moving
parts with grease�
•
The cogs on the centerline of the two marks on cogwheel
LV-207 should be aligned with LV-220 in the inward/inner
position on 08 hoist, in the inner/outer position on the 3�2 ton
hoist and in the neutral position on the 1�6 ton hoist�
•
Gently wipe both brake discs and friction surfaces that come
into contact with the washers using a dry cloth/rag� The
brake discs and friction surfaces must be oil-free and not be
greased!
•
The brakes are adjusted by setting the hoist in the neutral
position� The brakes are engaged by setting the UP/DOWN
selector in the middle position and pulling hard on the chain
on the side of the hook� The handle is set so the lifting
cog marked with a square is standing just above the gear
marked with a square
When maintenance is done on the hoist it must be approved by
an expert agency in accordance with national regulations�
PERIODIC INSPECTION
•
Annual periodic checks are required� The inspection must
be done in accordance with the manufacturer's maintenance
list� Of particular importance is verifying that brake coatings
are within tolerance limits set by the manufacturer� (See the
maintenance table)
WEAR THAT CAN CAUSE RISKS
•
The hoist is equipped with a precisely calibrated chain,
Grade T (8)� Wear on a chain that stretches the links is
not permitted because this can cause the chain to «climb»
on the chain wheel and get stuck� This is a personnel risk
because the load cannot be lowered properly�
•
The chain may only be replaced with a similar precisely
calibrated Grade T chain� One must never use a chain used
on electric hoists (type DT or DAT, ref� standard EN-818-7)
because these may not be used on manual hoists due to
their differing properties - thus leading to a risk of injury�
•
Hooks must not have larger openings than the maximum
limits stated in the technical data table
TRAINING IN USE
•
The users must read the manufacturer's instruction manual
before they are allowed to use the hoist�
•
There are no special qualifications for using a hoist besides
reading and understanding the instruction/user manual�
•
One prerequisite for the users of such hoists is having
undergone an introductory course or training in the use of
lifting tools and that equipment is used in accordance with
national regulations and the manufacturer's instructions�
CRITERIA FOR DISCARDING CHAINS/
HOOKS/BOLTS/BRAKE DISCS ETC.
Wear expansion max. 2% on 5 chain links:
Chain dimension:
Total inner length
4 mm
60 mm + 1�2 mm
5 mm

Corrosion that could influence chain properties is not permitted.
Brake discs
Brake discs for all tonnage rating must be of even thickness
when inspected�
Minimum thickness for all tonnage ratings = 2 mm
Tolerance on suspension
bolts/holes for top and bottom hooks
No wear is permitted on the bolts for the top hook/bottom hook
Production tolerances: 0.05 mm in relation to nominal dim.
(new bolt)
The bolt holes must not
have any sign of wear/oval shape
Production tolerances: + 0�2 mm
Hooks
Lasting deformations/expansion to hook openings is not
permitted in relation to the nominal dim.
Nominal dimensions:
Tonnage:
Dim. opening, in mm:
0�75/0�80 t
27 mm
1�00 t
30 mm
1�50/1�60 t
34 mm
3�00/3�20 t
43 mm
6�00/6�30 t
47 mm
Nominal dim� should be checked and logged for each hoist
before use�
Please Note! Deformations will not occur on hoists with
overload limiters if they are used correctly.
