2General safety notes
The products are constructed according to the state of the art and recognized safety
rules. However, during use danger to the life and limb of the user or a third party can
arise, or adverse effects can affect the product and other property.
2.1 Use for intended purpose
•Wire rope hoists are intended for lifting freely movable loads. Depending on their
design, they are for stationary or mobile use.
•In the case of wire rope hoists with multiple load-bearing equipment, ensure that the
load is distributed evenly between the falls.
•Any fundamental alterations and modifications to the product, such as e.g. welding on
load-bearing components, structural alterations to load-bearing components,
alteration of drives, alteration of speeds and motor outputs, replacing trolleys, etc.
must be authorized by the manufacturer, otherwise the declaration of
conformity/declaration of incorporation will be invalidated.
•Also any work on or additions to the control must be authorized by the manufacturer.
The manufacturer cannot accept any liability for malfunctioning after unauthorized
work on the control.
•The conditions in the place of use of the hoist must correspond to the operating
conditions for which the hoist was designed (including indoor/outdoor use, ambient
temperature, radiation temperature, wind, dust, splash water, snow, water, etc.
•For hoists which work in combination and have more than one control (tandem
operation), action must be taken to coordinate the controls. This applies also to the
reaction of the protective devices. Controls must be constructed accordingly.
•For hoists intended for automatic operation, the control must be designed
accordingly.

2.2 Inappropriate use
•Use in areas with potentially explosive atmosphere.
•Transporting molten metal.
•Exceeding the maximum working load.
•Transporting persons.
•Pulling/towing or raising/lowering of a guided load.
•Using the hoist in applications in which the working load changes with the position of
the load, as the hoist is not equipped with a load display and additional warning
device when it cuts off at overload.
•Breaking away, pulling or towing of loads.
•Use of rope drive for “guided loads” without being designed for this type of
application.
•Breaking away of tilted loads if the rope drive is designed for the “guided load”
application.
•Pulling loads at an angle, dragging loads or moving vehicles with the load or load
suspension equipment.
•Do not knot load ropes or chains or shorten them with devices such as bolts, screws
or similar.
•Removing the safety latch from suspension and load hooks.
•Manipulating the overload safety device.
•Operation with slack rope (loose windings on the rope drum).
•If the product forms “part of a machine”, the person placing it on the market must
ensure that the product meets the specific regulations of the application.
•Application of external torques due to forces that are exercised from outside the
system, e.g. with gripper operation or through tilting/bumping of the load, in particular
with the option 4×90° hook locking.
2.3 Residual hazards
The machine has been subjected to a risk analysis. The design and construction based
on this correspond to the state of the art. However, residual hazards remain during
operation and maintenance and these could result in serious or even fatal injuries to
personnel.
•Risk of crushing
•Hazard due to falling parts (attached to the load or on the load)
•Load toppling due to unsuitable or damaged load-bearing equipment
•Risk of electric shock
Preventative measures:
1. Use LOTO (Lockout/Tagout) procedure in accordance to national, state and local
regulations and company policy.
2. Switch the machine off and ensure it cannot be switched on again before carrying out
maintenance, cleaning and repair work.
3. Switch off the power supply before all work on the electrical system. Check that the
components to be replaced are free of current and voltage.
4. Do not remove any safety devices or override them by manipulating them.
5. When lifting or lowering loads ensure that no-one is in the immediate danger area.
6. It is forbidden for anyone to stand in the danger area.

3Introduction
Wire rope hoists are intended for lifting freely movable loads.
The modular concept of our series of wire rope hoists permits a multitude of variations on
the basis of series components.
The design is characterized by the rope drum and hoist motor being arranged in parallel.
The hoist drive is a cylindrical rotor motor with a separately activated D.C. brake. Its
design complies with the FEM calculation regulations which are adapted to the
requirements of hoist operation.
The main components of the wire rope hoist are the hoist motor, the gear, the rope drum
and the control box with connection parts.
Our certified quality assurance system to DIN ISO 9001 guarantees consistently high
quality.

Possible mounting positions and fleet angles
Feet “at bottom” and “at top” are possible for designs with bottom hook block (rope lead-
off vertically downwards).
The YK/SK wire rope hoist with 1PS and 1PS twin hook rope lead-off can be installed in
various positions (fleet angles see section 4.2 Fleet angle)
1. If possible, install the hoist in the preferred installation position ***
(see section 4.2.1 Attachment at bottom)
2. Use the fixing elements specified, see the following figures and tables.
3. Take care that no distortion arises from unevenness (see figure item A = max. 0.5°,
item B = max. 0.079 in).
4. The customer's substructure must take up the torque MTfrom the rope drum. It must
therefore be torsion resistant.
5. If the rope lead-off is not vertical, the shearing forces arising must be taken up by a
shear bar.
6. For tightening torques see chapter Tightening torques.
