7.2Maintenance tasks
7.2.1General prerequisites
Prior to performing repair and maintenance tasks, do the following:
• If vertical axes are present, secure them against falling
• Switch off the system and padlock it to secure it against being switched on
again
• Make sure that all necessary spare parts and wearing parts are at hand
Ü291
7.2.2Maintenance intervals
The product is subject to natural wear and tear. When it wears out, unplanned downtimes of your system can result. Güdel specifies the service life
and maintenance intervals of the product so as to ensure safe and continuous
operation. The maintenance intervals relate to the effective operating hours
of the product at a power-on time (POT) of 100%. Normal operating conditions are assumed. These correspond with the parameters used by Güdel
when designing the product. If the conditions are rougher than assumed,
products may fail earlier. Adjust the maintenance intervals to your operating
conditions if necessary.
For the general inspection, perform a rough check of the entire product.
Perform the general inspection as follows:
1Switch off the system and padlock it to secure it against being switched
on again
2Check the inspection points as described in the inspection table
3Take measures as described in the inspection table
Attach the slings as follows:
1Loop the lifting belt around the planetary gear (be aware of center of
gravity!)
2Hook the lifting belt into the crane hook
3Carefully lift the load
4Check horizontal alignment of the load
5If the load tilts, reposition the lifting belt loop
Improper handling of suspended loads can lead to severe injuries or death!
• Use appropriate lifting units
• Wear appropriate protective clothing
• Always keep sufficient distance from suspended loads
• Never enter the area below a suspended load
