Abstract
A passage barrier (10) with two barrier elements (24, 26) and two mutually aligned shafts (16, 20) which are separate from each other and can be driven by separate motors (14, 22), whereby one barrier element (24, 26) is retained on each shaft (16, 20), and can be swivelled independent of the other barrier element (26, 24) by driving the corresponding shaft (16, 20).

A passage barrier comprising:
- two adjacently arranged passage areas;
- a first barrier element and a second barrier element, each of which serves for optional blocking or opening of one of the passage areas;
- and
- an arrangement comprising:
- a first shaft and a second shaft which are mutually aligned in a columnar manner and axially separated from each other such that they can be driven independent from each other;
- a first motor and a second motor, wherein the first shaft is driven by the first motor and the second shaft is driven by the second motor;
- and
- wherein the first shaft and the second shaft as well as the first motor and the second motor extend vertically upwards in a columnar manner;
- wherein the first barrier element is retained on the first shaft so that in case of rotary motion of the first shaft the first barrier element is swivelled together with the first shaft, and wherein the second barrier element is retained on the second shaft so that the second barrier element will follow the motion of the second shaft.
