Hägglunds Fusion Drive system
| Installation
Bosch Rexroth AB, RE 15345-WA Version 11.2022,
Example:
Weight for complete unit for combination CB 840-840 with shrink disc coupling,
125 cc pump and 75 kW electric motor 3300 kg.
Angle of inclination of the chain 45°. Gives W
LL
= 3300/(2*0,71)
=
2324 kg. Gives
safety factor above 4 but below 8 according to
Hints for assembly load ring:
The load rings must be rotatable 360° when installed. Please observe the
following:
•
For a single use hand tightening with a spanner is sufficient. Bolt supporting area
must sit proper on bolt-on surface

Note!
The Drive System shall only be lifted without top panel
The working load limit of individual load ring are calculated using the following
formula and are based on symmetrical loading:
W
LL
= working load limit
G = load weight (kg)
n = number of load bearing leg
ß = angle or inclination of the chain to the vertical
G = Weight of Hägglunds Fusion. See
n = 2 (due to asymmetrical load)
ß = 0 - 45°
cos 0° = 1
cos 30°
= 0,87
cos 45° =
0,71
