Installation
6.1
Adjusting the gauge
The trolley can be adjusted to various beam flange widths. Adjustment to the relevant beam flange width “B”
depends on the type and size and is to be made as follows:
 There are distance tubes (5) and/or washers
(6) situated on the load bars (2) of the trolley.
 Dimension "X" is set by placing washers (6)
from the outer to the inner side ("X" increases)
or from the inner to the outer side ("X"
decreases).
 Washers (6) and rubber discs (depended on
type) leave a distance for the load hook. It is
important that the load hangs in the middle
under the beam so that the two side plates are
equally loaded.
 The suspension eye (9) (if existent) for bigger
load bolts must still be swivelling after it has
been secured.
 Tighten the hexagon nut (3) and safety nuts (4)
again.
 Check correct flange width "B" and dimension
"X". Adjustment must be repeated if necessary.

WARNING!
If one or several of the dimensions fall below or exceed the dimensions in the table, or if cracks or
corrosion are found, the parts must be replaced with original spare parts.
12.2
Checking the load chain
CAUTION!
The load chain must be tested over its entire length!
The measure of the load chain must be carried out especially in the areas which are subject to the highest
wear. Through the lifting movement, these are the contact points of the chain with sprocket wheel and
deflection pulleys.

13.1
Load chain
Wear at the links is mainly due to insufficient maintenance of the chain.
To ensure optimal lubrication of the links, the chain must be lubricated at regular intervals, depending on
usage.
 Lubricate the chain with oil that creeps.
 Always lubricate the chain when it is not under load so that the oil can wet the links affected by wear. It is
not sufficient to lubricate the chain from the outside, as this will not ensure the formation of a lubricating
film within the links. The adjacent link points must always be lubricated to prevent excessive wear.
 If the same lifting operations are carried out constantly, the switching area from a lifting to a lowering
movement must be given special attention.
 Thoroughly effected lubrication of the chain will prolong the life of the chain by approx. 20 times,
compared to dry run with unlubricated chain.
 Wash dirty chain with petroleum or a similar cleaner, under no circumstances heat the chain.
 If there are environmental influences that foster wear, such as sand, a dry lubricant should be used, e.g.
graphite powder.
 When lubricating the chain’s condition of wear should be checked.

Regular checks of lubrication are necessary. The teeth must be cleaned and re-lubricated after approx. 3
years. We recommend to use a lubricant of class EP2 or similar products. In case of severe conditions of
use (e.g. dust, regular lifting of the nominal load,etc.), please shorten maintenance intervals.

During the check, brake lining wear is verified. The brake linings must be replaced when the wear limit is
already reached at one position of the lining, - as this can be the case when wear of the linings is irregular.
CAUTION!
The brake linings must be free from fracture. Avoid oil, grease, dirt and humidity on the brake linings as this
increases wear.
