The bridge supports open load bearers (9.1, 9.2) directed towards one another, each having a lower horizontal lifting arm (9.3). The respective lifting arms on one or more first load bearers are directed from one side inwards under the load and on one or more second load bearers directed from the other side inwards under the load. This enables the load to be supported only by the first load bearers or only by the second load bearers or by all the load bearers together. |
