3.2.8 Suspension parts

All statically loaded parts are considered suspension parts. The bearing surfaces of the slewing suspension parts must be periodically greased.
Torque values for screws of property class 8.8 according to DIN ISO 898:
M 5 M 6
6 Nm 10 Nm

4 Measures for obtaining a safe period of operation

The statutory and health requirements of the EU regulations stipulate that specific dangers which may arise from fatigue or ageing must be
prevented.
Accordingly, operators of standard hoist gear are obliged to determine the actual utilization. The actual utilization period is determined and
recorded as part of the annual inspection by customer service engineers. A general overhaul must be carried out when the theoretical utilization
limit is reached, or after no more than 10 years.
All checking and the general overhaul itself must be arranged by the operator of the hoist gear. The following theoretical utilization periods apply
to electric chain hoists that are categorized according to ISO 4301-1 (converted into full-load hours):
M3 M4
400 h 800 h

4.1 Determining the actual utilization period S

The actual utilization period depends on the daily operating time and the load collective.
Running time is determined from information provided by the operator or recorded using a meter that counts the number of operating hours. The
load collective is determined in accordance with table 1-1, page 9. These two items of information are used to calculate the annual utilization
period from table 4-1.
If an operating data acquisition system (BDE) is used, the actual utilization can be read out directly by our experts during the annual inspection.
CAUTION !
The values periodically calculated or read-off must be recorded in the log book.

4.2 General overhaul

On reaching the theoretical service life (no later than 10 years for recording without BDE), a general overhaul should be performed. This enables
the equipment to continue operating safely for a further period of utilization (service life). Components must be inspected and/ or replaced in this
overhaul according to table 4-2. Inspection and approval for further use must be performed either by a specialist company authorized by the
manufacturer, or by the manufacturer personally.
The inspector determines: –
–
This data should be recorded in the log book.
