3.4 Assembly door frame on the car roof
NOTE:
The sequence of the assembly specified here shows only a recommendation. There is not
a requirement on completeness.
3.4.1 Before disassembly the old door operator
Before the disassembly of the old door operator must be taken up the following mass.
1. Height of track of car roof (car internal height)
upper edge of track to car roof.
2. Track:
- closing edge extremely needed measure consider (pay attention to lines and other obstacles of
shaft wall by passage),
- opening edge extremely needed measure consider (pay attention to lines and other obstacles of
shaft wall by passage),
3. depth of installation of the track (back of track to car),
NOTE:
The new track has the same length and mass as the old one.
3.4.2 Disassembly the old door operator
The old door drive must be dismantled completely. The clamping plates at the old door drive must be un-
screwed, since they are again used.
3.4.3 Door operator on car
Put the new door operator on car (provisional attachment by fighter mounting plate e.g. by fastening
clamps).
The height, lateral position and the depth of the door operator depends on the track. The mass, which were
taken up before the disassembly of the old door operator, are to be kept with the new track.
NOTE:
Build door operator horizontally and in the plumb!
For security an inspection drive should be accomplished, in order to recognize possible ob-
stacles and to correct the position of the door operator. It makes certain that also the su-
pernatant double toothed belt disks do not affect the shaft wall or obstacles at the shaft wall
