Abstract: The invention relates to a crane, particularly a bridge crane or gantry crane, including at least one crane girder extending horizontally and designed as a truss with a plurality of braces, on which girder a crane trolley with a lifting gear is movable. At least some of the braces have a flat shape. The flat-shaped braces each have a flat main surface that extends in each case transversely to a longitudinal direction of the crane girder.

Abstract: The invention relates to a circuit arrangement comprising a hoist controller (12) of a hoist (10), a control pendant (12) having an emergency stop switch (2), and a control line (3) which electrically connects the hoist controller (12) to the control pendant (12) and has a control voltage applied thereto. In order to provide a circuit arrangement for monitoring an emergency stop switch of a hoist having a pendant switch, which circuit arrangement can be used to reliably detect a short circuit, it is proposed to assign a controller (1) to the emergency stop switch (2), which controller superimposes a cyclical pulse on the control voltage, and to design the hoist controller (12) in such a manner that said hoist controller monitors the cyclical pulse and switches the hoist (10) to a safe state in the absence of the cyclical pulse.
