User manual for medifa 5000 operating table Version 2.1
10. Standard rails
The standard rails on the right and left of the table top are used to attach accessories.
WARNING
Risk of personal injury due to tilting of the medifa 5000!.
Irrespective of the permissible load of the individual standard rails, a total unilateral torque of 70 Nm over
the longitudinal axis and 100 Nm over the transverse axis of the medifa 5000 must not be exceeded during
intended use!
In addition to the risk of tipping over, the standard rail can break if the load limit is exceeded. As a result, the
patient’s body part supported on the accessory can slip away, which poses the risk of inserted cannulas being
pulled out.

Figure 3: Torque on standard rail
The maximum permissible torque on a standard rail of the medifa 5000 is 70 Nm around the longitudinal axis
and 100 Nm around the transverse axis. The torque is applied as soon as an accessory is coupled to the standard
rails. The dead weight of an accessory used can be taken from the
accessories list!

Maximum permissible torque
M (L or Q) = m x L x 10
Torque [Nm] = Mass [kg] x Length [m] x 10[m/s2]
For the mass (m), specify the weight of the patient body part to be placed on the accessory.
