kept  in  a  suitable  place  for  future  reference  and  must  be  available  for 
any assembly, maintenance or dismantling work. 

2.2

 

Target group 

This documentation is intended for qualified trained personnel who are 
familiar  with  mechanical  assembly  work.  Assembly,  commissioning  and 
maintenance may only be carried out by accordingly qualified personnel. 
Technical training or safety instruction is required. 

2.3

 

Scope 

The  scope  of  these  instructions  covers  the  following  products  of  the 
company EGT Eppinger Getriebe Technologie GmbH: 

 

HT Hypoid gearboxes 

 

SHT Hypoid helical gearboxes 

All  mounting  parts  necessary  for  the  assembly,  installation,  operation 
and  maintenance,  which  are  included  in  the  scope  of  supply  of  these 
gearboxes, are also within the scope of this document. 

2.4

 

Intended use 

Eppinger  gearboxes  are  machine  elements  for  converting  or  diverting 
torques  and  rotational  speeds  within  the  respectively  specified  perfor-
mance  range.  Any  operation  outside  the  specified  performance  charac-
teristics or other than the specified use is not permitted. The permissible 
torques  and  rotational  speeds  of  the  gearboxes  must  not  be  exceeded. 
The forces affecting on the gearbox shafts have to be limited to the max-
imum permissible values. 

Unauthorised modifications or alterations to the product are not permit-
ted. 

According  to  the  EC  Machinery  Directive  2006/42/EC,  gearboxes  are  re-
ferred  to  as  machine  components  and  are  therefore  assemblies  that  do 
not  fall  within  the  scope  of  the  Machinery  Directive  2006/42/EC.  There-
fore, gearboxes are components to be installed in machines. The commis-
sioning is forbidden until by or after the integration into the end prod-
uct, the requirements of the machine directives are met.
