Method for braking a revolvable superstructure of a working machine and a pivoted brake unit

A pivoted brake unit for braking a revolvable superstructure of a working machine having a superstructure driven by a motor via a transmission, the pivoted brake unit comprising:

• (a) a pivoting pump arranged in a closed hydraulic circuit with the motor and the transmission;
• (b) a control valve which transmits control signals to said pivoting pump;
• (c) a control lever operating said control valve comprising at least one neutral position and at least two switching positions, each of said at least two switching positions corresponding to an opposing direction of revolution of the superstructure;
• (d) a switching logic circuit coupled to said pivoting pump and actuated by said control lever;
• (e) a monitoring device coupled to said switching logic circuit for monitoring a number of revolutions of the superstructure;
• wherein said switching logic circuit automatically brakes a revolution of the superstructure by counter-steering when said control lever is in a braking position and wherein said switching logic circuit stops braking revolution of the superstructure by counter-steering when said monitoring device detects that the superstructure has come to a standstill.
