In a method for preventing a collision of a load of a crane with an obstacle, a height profile of the obstacle is captured along a trajectory of movement of the load by at least two sensors for distance measurement. Signals of the sensors are transmitted via at least two communication channels to a controller having at least two operating systems. At least one of the operating systems has a safety program in a secure area. The obstacle is identified along the trajectory via the height profile. The controller includes a secure communications interface for transmitting signals from the controller to a crane control.

Method and system for avoiding collisions in cranes

A press with a cylinder for the movement of a pressure element is described. The cylinder is connected to a toggle lever, wherein the toggle lever is connected to a drive and wherein the drive moves the cylinder via the toggle lever.

Press

There is described a method for motion monitoring of a machine, comprising a sensor, wherein a sensor signal is transmitted from the sensor to a controller and/or to a drive device, a failsafe controller or drive device being employed as controller or drive device. The controller or drive device comprises three independent monitoring devices in which the sensor signal is formed from a first and a second redundant actual position value.
