The entire system must be accepted by a crane expert or crane specialist.
The legal regulations and safety regulations applicable at the location of use must
be adhered to during use of the chain hoist.
1.7 Intended Use
Schmalz chain hoists are intended solely for lifting loads. The loads are raised using special load-
bearing devices (e.g. lifting magnet or VacuMaster lifting device). They can be used as both stationary
and movable machines. The chain hoists are state of the art and manufactured in accordance with the
recognized technical safety regulations. They are checked for safety by the manufacturer. The chain
hoists are approved by independent classification companies (BG, among others).
The chain hoists in the above-mentioned series must only be used when in perfect technical working
order, in accordance with their intended purpose and by safety-conscious and hazard-aware trained
personnel.
The maximum permitted lift capacity and the drive group must be observed (see the type plate and
chapter 3).
1.8 Non-Intended Use
WARNING
Using the lifting device to transport humans or animals, or as a climbing
aid
Fall hazard
►
Use of the chain hoist as a climbing aid or to transport people or animals is
prohibited.
Non-intended usage includes the following:
Exceeding the maximum permitted load
Carrying loads at an angle (see Fig. 1)
Allowing loads to rock
Storing suspended loads
Inching or positioning operations
Traveling to the mechanical end stops
Pulling, dragging or tearing loads free
Fig. 1

The manufacturer accepts no liability for damages caused by non-intended usage.
1.9 Requirements and Instructions for Installation, Maintenance and
Operating Staff
The chain hoist must only be installed and maintained by qualified specialist personnel, mechanics
and electricians. Work on electrical equipment must only be carried out by qualified electrical
specialists.
The operator must ensure that any people charged with installing, starting operations
on, operating, maintaining or repairing the chain hoist:
Are at least 18 years of age
Are mentally and physically fit for the task
Have been trained in operating and maintaining the chain hoist
Have read and understood the operating instructions
Can be expected to reliably perform the tasks assigned to them
The operating instructions must be accessible at all times.
The type plate and warning signs must be legible.
The operator is obligated to perform a risk assessment for the ambient conditions at
the installation location.
A qualified employee is defined as an employee who has received technical training and has the
knowledge and experience –including knowledge of corresponding regulations –necessary to enable
him or her to recognize possible dangers and implement the appropriate safety measures while
performing tasks. Qualified personnel must observe the pertinent industry-specific rules and
regulations.
Atechnical expert is an employee who, based on his or her technical training and experience, has
sufficient knowledge in the field of chain hoists and is sufficiently familiar with the applicable national
occupational safety regulations, accident prevention regulations, directives and generally accepted
technical guidelines, such as BG regulations [German workmen’s compensation], DIN standards, VDE
guidelines, technical guidelines from other European Union Member States or other European

Economic Area member states, to determine whether or not the chain hoists are in good working
condition.
In addition to the experts for technical supervision, the only people considered to be experts for
inspecting chain hoists are persons identified as authorized experts by the trade association.
1.10Installation Location Requirements
DANGER
Switching components that are not explosion-proof
Risk of fire and explosion
►
The chain hoist may not be used in areas exposed to explosion hazards.
The chain hoist is designed for both indoor and outdoor use. If the chain hoist is to be used
outdoors, a protective roof is recommended to protect against weather conditions.
The ambient temperature must lie within the range of –15°C to +50°C.

The operator’s work station is sufficiently lit and free of glare
The work station environment is neat and clean
1.12Danger Zone Definition
When lifting or transporting the load, it is possible that the load could fall, which is why the area
directly under the crane system and the chain hoist is always considered a danger zone.
1.13Personal Protective Equipment
