4.3 Functions
The load is lifted or lowered by pulling one of the chain falls of the endless hand chain of the hoist. A load
pressure brake prevents automatic lowering of the load after releasing the hand chain.
In combination with hand geared trolleys, the trolley is moved to the left or to the right side by pulling the
hand chain.
In combination with push travel trolleys the trolley is moved by pushing or pulling the load or, without load, by
pulling the load chain.
NOTICE!
The best protection against functional failures in case of extreme environmental impact is the regular use of
the equipment.
4.4 Important components
Gear
Gear components are made of high-quality material.
Load pressure brake
Holds the load in any position. Hardened safety pawls.
Housing
Depending on the model made from steel plate or aluminium die-casting (Not for explosion proof equipment).
In case of ex proof hoists, the housing is only made of steel plates.
Load chain
According to EN 818-7-T high quality chain. All components match precisely to each other. Therefore please
only use original chains.
Load hook
Forged steel. Rotating, this facilitates attaching the load and avoids twisting of the chain. With safety catch.
Overload protection
Hoists with overload protection protects the hoist by a slipping clutch from damage by overload. When the
slipping clutch operates, lifting of the load is stopped. Lifting is only possible again after the load has been
lowered and reduced to nominal load.
Special Parts
For use in explosion dangerous areas, are be installed some special units, special treated surfaces or made
in special material.

6 Installation
DANGER!
Assembly, disassembly and maintenance operations must only be carried out in an atmosphere not
prone to explosion!
The assembly and installation depends on the local environment. The hoist must be suspended in a way that
it can position itself freely.
6.1 Trolley
For assembly on a beam a travel limit must be placed at either end of the track.
This must be attached so that any elastic limitation buffer or the trolley wheels are driven against them in
their end position when moving.
Generally, additional lifting gear (e.g. fork lift, lifting platforms) will be required for the assembly. These must
take the weight of the devices securely.
6.2 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.

8.2 Load chain
Before commissioning the load chain must be aligned and oiled.
Move safety note and fixing wire away from the chain.
CAUTION!
Do not use grease for lubrication of load chain.
Without lubrication, manufacturer's warranty and/or liability will be void.
NOTICE!
Continuous, thorough lubrication will increase the life of the chain considerably.
9 Safety check
Before putting into service initially or when putting back into service, it must be checked whether:
All fastening screws (if existent), socket pins, flap socket and safety devices are tightened and secured.
The chains are correctly placed, oiled and in good condition.
10 Functional test
10.1 Checks before the initial start-up
Lifting gear
Load chains must not be twisted.
Lubricate the load chain with gear oil or suitable chain lubricant before first loading.
Trolley drive
The open-lying teeth of the trolley drive must be lubricated.
Hand gear for hand geared trolley
Ensure correct fit of the hand chain, it must not be twisted and must hang freely.
10.2 Functional test
Lifting gear
Check lifting and lowering functions, initially without a load.
Then check the brake function under load. The load must be securely held.
Trolleys
Carefully move the trolley to the end positions and check the positions of the end stops.
11 Maintenance
11.1 General
All monitoring, servicing and maintenance operations are to ensure correct functioning of the equipment;
they must be effected with utmost care.
Only “qualified persons” may do this work.
Servicing and maintenance work must only be done when the hoist is not loaded.
Records must be kept of all test results and measures taken.
11.2 Monitoring
The monitoring and servicing intervals stated are valid for operation under normal conditions and single-shift
operation. In case of severe operating conditions (e.g. frequent operation with full load) or special
environmental conditions (e.g., heat, dust, etc.), the intervals must be shortened correspondingly

18 5.52.127.01.01.02
11.3 Replacing the load chain
CAUTION!
If there is any visible damage and when the conditions for replacement are reached (i.e. one or several
dimensions in the table have been reached, there is corrosion or elongation), the chain must be replaced.
When replacing the chain, also check the chain wheels.
Procedure:
Only insert new chains in an unloaded state and as the chains that are currently in the device – i.e. not
twisted.
Remove chain from its fastening at the end and attach a chain link which is open at the side.
A chain link which is open at the side, can
easily be produced by grinding out a small
piece. The opening must have the same
thickness as the chain link.
Illustration 9
Hang a new original chain (same size and oiled) in the side opened chain link and insert it.
Make sure the chain is not installed twisted.
Make sure the chain links are aligned in one direction.
Assemble the chain to the end fastening.
12 Inspection

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 Service
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.
