Advice for the use of electric chain hoists
1.2.1
Design according to DGUV V54 (BGV D8)
Electric chain hoists are designed to lift and to lower loads vertically and to travel horizontally with those lifted loads
(with trolleys).
Any other use is not considered to be proper. Manufacturer does not take responsibility for any improper use and the
risk is on the operator’s responsibility.
The use of the electric chain hoist in an aggressive environment is not allowed without permission of the
manufacturer.
To this effect, it may be necessary to make certain components from different materials.
The electric chain hoist can only be operated by personnel, who have complete knowledge of this manual, and have
unhindered access to it. Do not operate the electric chain hoist until all operators have thorough knowledge of this
manual, and acknowledge that by signing the allocated field on the rear cover of this brochure.
If properly used, the modern design of the electric chain hoists guarantees safety and economic
operation.
The safety friction clutch is located outside of the load path, which enables stopping the load without
putting strain on the clutch. The force of the brake acts via a form-locked join on the gear and therefore
it will be directly transmitted on the load.
Before first use make sure, that all electrical wires are connected in accordance with the instructions,
that all wires are without damages and that the whole equipment could be switched off by a main
switch. It is the responsibility of the operator to make sure that all suspension points of the hoist are
designed to safely withstand the dynamic forces caused by the lifting equipment.
The chain hoist can only be used when it is suspended according to specification and the outgoing
chain can leave the hoist safely, by its own weight, in the relevant direction.
Therefore the container for the dead end of the chain outside the hoist must be big enough to allow the
chain to come out.
If not, the chain can be trapped inside the hoist and can break the casing of the hoist.
Maintenance work on electric chain hoists has to be carried out by trained and authorised people only.
The main switch has to be switched off and the working area is to be secured beforehand.
Authorised people
have to have a theoretical training as well as experience in the field of winches, lifting and pulling
equipment or cranes. They have to possess an excellent knowledge of the relevant work safety regulations,
directives, and general accepted rules of lifting techniques, which enables them to decide whether the lifting
equipment is in a safe working condition or not.
Any maintenance work and inspections are to be entered into the crane inspection book (e.g. brake or clutch
adjustments).
This manual will tell you how to operate the hoist and how to handle its suspension or its loads safely. The following
safety advices have to be observed. The safety instructions may not be complete for each mode of use. If there are
any questions or problems contact the manufacturer or our local representative.
This Operating Instructions should always be in a complete and fully readable condition.
No responsibility is taken for damages and operating troubles due to the following reasons:
•
improper use
•
unauthorised modification of the drive system
•
unworkmanlike work done on the system and with the system
•
operating errors
•
Failure to use the product as instructed in the manual
