RISK ASSESSMENT
Before using a Lodestar D8 Plus chain hoist and the associated
work equipment, the user must assess the hazards to be expected
(risk assessment), and describe and implement the necessary and
suitable protective measures.
The presence of a CE marking on the Lodestar D8 Plus chain
hoist does not release the user from the obligation to carry out a
risk assessment.
The risk assessment must include all allocated hazards that can
occur when using the Lodestar D8 Plus electric chain hoist.
These risks include not only those that can arise from the electric
chain hoists themselves, but also those that can affect the working
environment (e.g. weather conditions when used outdoors).
RISK ASSESSMENT BEFORE USE
The risk assessment must be drafted before the selection
and integration of the Lodestar D8 Plus electric chain hoists.
The risk assessment may only be carried out by competent persons.
An expert must be commissioned if the user does not possess
the appropriate knowledge.
The risk assessment must be documented in writing.
RISK ASSESSMENT BEFORE EACH USE
Individual application-related (scenic motion) risk assessments
MUST be carried out due to the large number of possible uses the
Lodestar D8 Plus chain hoist can be utilised for in event technology.
Elements to be considered:
- Mechanical risks.
- Electrical risks.
- Risk due to the working environment conditions.
- Danger from physical stress and work severity.
- Risks due to the lack of organisation.
Circumstances to be considered:
- Presence of persons under loads.
- Type of loads to be lifted.
- Emergency or hazardous situations.
- Competence and experience of users.
- Time frame.
The risk assessment should take place during the
planning phase and must be documented in writing.
When using electric chain hoists in event technology, risks due to
the use of technical protective measures can only be minimised
to a limited extent in individual cases. In such cases, electric
chain hoists can only be used with special care.
INTEGRATION
Before integrating Lodestar D8 Plus chain hoist and the chosen
work equipment, the following points must be considered:
SITE CONDITIONS
The condition of the on-site attachment points must be visually
checked, and the load-bearing capacity of the attachment points
must be ascertained based on the operator documentation
and information.
LOAD CHAIN
- Electric chain hoists are to be mounted so that the chain does
not rest on anything and cannot run in at an angle. In particular,
the fastening of a load (e.g. truss construction) on several electric
chain hoists must not cause any slack run in of the chain.
- The chain of an electric chain must be able to run safely
into the chain container.
- It must be ensured that the chain can freely run in
and out without obstacles even when unloaded.
- When using double reeve electric chain hoists, make sure
that the chain strands are not twisted.
These integration guidelines are in addition to the safety
guidelines present in the Lodestar D8 Plus user manual!
COMPETENT PERSON
- The competence or qualification of those involved in planning,
construction and dismantling the machinery operation depends
on the degree of risk and the output of the risk assessment.
- As general guideline, a competent person is a person with
sufficient practical and theoretical knowledge and experience
to carry out the person’s duties, and who is aware of the limits
of the person’s competency, expertise and knowledge.
COMMISSIONING
The Lodestar D8 Plus electric chain hoist may be used to hold
loads over persons without a secondary safety component.
For the “at rest” state, the operating coefficients of all elements of
the electric chain hoist located in the power flow must be known
and must be dimensioned for at least twice the load capacity of
the D8 Plus electric chain hoist.
The Lodestar D8 Plus electric chain hoist is equipped with a direct-
acting hoisting force limiter (slipping clutch), but it must not be used
for the protection against overload. Lodestar D8 Plus electric chain
hoists may be supplied with additional safety features such as, for
example, indirectly acting lifting force limiters (e.g. load cells, load
pins), limit switches and encoders.
The requirements of such safety-related devices is the consequence
of the risk assessment being carried out by the user.
As a general rule, a load cell system should be used as an overload
device, every time a Lodestar D8 Plus system is installed.
Load monitoring and measurement is ALWAYS required if there
is the possibility to overload a load-bearing element.
OPERATORS
- The operator must always be able to see the lifting operation of a
Lodestar D8 Plus electric chain hoist and its load throughout the
entire travel distance. If this is not possible, suitable measures for
monitoring the lifting process must be defined and implemented.
- If several electric chain hoists are used to lift a shared load with
more than one control, it must be ensured that the lifting process
is triggered over a common command device and that the lifting
process can be interrupted by a common emergency stop.
- The operator should perform the lifting operation based
on the output of the risk assessment.
