3.12 Loading the side rails
Risk of personal injury and material damage when exceeding
permissible loads
• Regardless of the permitted load capacity of the individual side
rails, the one-sided total torque around the longitudinal axis of
the operating table may not exceed 100 Nm / 73 ft·lb during
normal use.
The maximum permitted torque on an operating tabletop side rail
is 100 Nm / 73 ft.lb around the longitudinal axis and 150 Nm / 110
ft.lb about the transverse axis. Torque exists as soon as an
accessory is coupled to the side rail.
In the following table, torque is specified in accordance with
weight and distance for some standard situations.
Torque around the longitudinal axis:
