It is the responsibility of the operator to ensure that no
unauthorised personnel work on the lever hoist (e.g.
also by working on equipment in a manner contrary to
authorised use).
It is the responsibility of the operator to check the lever
hoist at least once before use (once a day) for externally
apparent damage or defects and to report any changes
(including to the way the machine is operating) which
are likely to compromise safety.
It is the responsibility of the operator to ensure that the
the lever hoist is operated only in perfect order and con-
dition.
It is the responsibility of the operator to insist that oper-
ating personnel must wear protective clothing wherever
necessary.
Under no circumstances must safety devices be re-
moved or put of operation (potential risk of serious
crushing, danger to life).
If it is necessary to remove any safety devices for fitting,
repair or maintenance work, they must be reinstalled im-
mediately after maintenance or repair is complete.
2.7 Checks
Hoisting chains are classed as a load-carrying device
requiring inspection. For this reason, the following
guidelines issued by the trade association central office
for accident prevention regarding round steel chain
used in lifting operations must be complied with: DIN
685 Part 5 Nov. 1981, UVV, BGV D8 (VBG 8 April 1997)
and UVV, BGV D6 (VBG 9 April 2001) and DIN EN 818-7
September 2002.
A record of maintenance and inspections carried out
must be entered in the crane inspection log book (e.g.
any adjustment to the brakes or clutch).
3 Intended use
The lever hoist is used exclusively for manual vertical lift-
ing and lowering as well as for pulling and lashing freely
movable loads up to the specified maximum load.
The lever hoist may be operated only by personnel who
have been trained in its use.
The proper use also includes observing all indications in
these operating instructions. Any use beyond the proper
use or any other use is regarded as misuse. Under no
circumstances may personnel be lifted.
Stürmer Maschinen GmbH accepts no liability for any
constructional or technical modifications carried out on
the lever hoist.
Any claims due to damages because of not intended
use are excluded.
3.1 Foreseeable misuse
If the intended use is observed, any reasonably foresee-
able misuse which could lead to hazardous situations
with personal damage is impossible with the lever hoist.
3.2 Residual risks
Even if all safety regulations are observed a residual risk
in the operation of the lever hoist will remain, as de-
scribed below.
All persons working with the lever hoist must be aware
of these residual risks and follow the instructions which
prevent any accidents or damage caused by these re-
sidual risks.
- Risk of crushing of upper and lower limbs while
equipment is operating.
- During set-up and adjustment works it may be-
come necessary to remove safety devices in-
stalled by the customer. This causes different re-
sidual risks and hazard potentials each operator
must be aware of.

The spring (41, spare part drawing) has to be replaced
as soon as the length has reached the limit in the follow-
ing table.
* The concrete value has to be measured at the new spring.
Fig. 11: Length of the spring
10 Testing of the lever hoist
The hoist must be tested by a qualified person for safe
operation in accordance with the provisions of the Ger-
man Industrial Safety Regulation and the BGR 500,
Chapter 2.8, before first use and as required at intervals
of no more than 1 year.
A person may be considered qualified if he / she has at
least the qualifications that previously were given to the
expert. The scope of testing and the inspection dead-
lines have to be carried out i.a. according to the results
of the risk assessment.
Type, extent and deadlines of the tests described in the
BGR 500 are previous practice and comply with the
rules of technology. The test is essentially a visual and
functional test. It covers the examination of the condition
of the components and equipment, the completeness
and effectiveness of the safety equipment and the com-
pleteness of the inspection book.
If an inspection period of no more than one year is ad-
hered to, the operator can assume that this period is
sufficient. The results of the checking of the chain hoists
has to be written down in an inspection book.
