Inspections
§ 39, VBG 9 A of the German employers' liability in-
surance association accident prevention regulations
requires that load-carrying equipment be inspected
by a qualified expert and possible defects be elimi-
nated prior to initial commissioning by the recipient.
§ 40, VBG 9 A requires that load-carrying equip-
ment be inspected at least annually for cracks.
When used in dynamic applications, equipment
must be inspected for cracks every six months.
Maintenance
You are authorized to replace easily serviceable
wearing or standard parts in accordance with the
manufacturer's instructions. Use original parts for
this purpose. If necessary, tighten screws and scre-
wed connections.
Repair
In the event that parts of the load-carrying equipment
have been deformed, it is up to the manufacturer
to determine if they are repairable. Solely the
manufacturer is authorized to perform welding and
repair jobs on load-carrying equipment.
3.3 Technical Specifications
of the COHEDRA
® Rigging
Hardware
Load-carrying capacity of standard rigging frames:
800 kg
Test load: 3,200 kg
Ambient temperature when in operation:
min. -10° C, max. + 60° C
3.4 Maximum Permissible
Number of Flown COHEDRA
®
Mid/High Units
• You may fly up to 32 mid/high range enclosures in
a stacked array.
• You may fly up to 24 mid/high enclosures in a
stacked array when using the standard rigging
frame.
• If you want to fly up to 32 mid/high enclosures,
you must use the high-load rigging frame! It is
available on demand.
Warning: Flying more than 24 enclosures in a sta-
cked array from the standard rigging frame voids
the safety standards authority TÜV's certification!
Refer to table 1 to determine flown loads. The sum
of the weights of COHEDRA
® mid/high enclosures
plus the weight of the rigging frames equals the
total load.
Note: Ensure that you add the weights of chain
hoists, motors, cables and further stops to determine
total weight!
