Abstract: The present disclosure relates to a working machine, comprising an electric traction motor configured to apply a torque on at least one wheel of the working machine during propulsion, an electric power system electrically connected to the electric traction motor; the electric power system being configured, during propulsion, to supply electric power to the electric traction motor, an emergency stop actuator arranged on an exterior surface of the working machine, the emergency stop actuator being electrically connected to the electric power system, wherein the electric power system is configured to cut off the electric power supply to the electric traction motor upon actuation of the emergency stop actuator, and a frame structure connected to the working machine, the frame structure comprising an abutment surface, wherein the frame structure is operatively arranged to move from a first position in which the abutment surface is arranged at a distance from the emergency stop actuator, to a second position in whi

Abstract: A suspension system for a vehicle includes a first suspension arrangement including a first hydraulic cylinder; a second suspension arrangement including a second hydraulic cylinder; and a valve unit between the first and second hydraulic cylinders. The valve unit is controllable between a first state in which a piston side of the first hydraulic cylinder and a piston rod side of the second hydraulic cylinder are in fluid communication, and a piston rod side of the first hydraulic cylinder and a piston side of the second hydraulic cylinder are in fluid communication; and a second state in which the piston side of the first hydraulic cylinder and the piston side of the second hydraulic cylinder are in fluid communication, and the piston rod side of the first hydraulic cylinder and the piston rod side of the second hydraulic cylinder are in fluid communication.
