The invention relates to a release system for a device which can move or travel, especially for a construction machine, said system containing at least one control circuit (8) for controlling and carrying out various functions. A release circuit (2) is provided which supplies an authorisation code to a release processor (10) after receiving a release signal. Said release processor (10) checks the authorisation code, and activates the control circuit (8) when the validity of the authorisation code has been established, thereby releasing said device. If the authorisation code is considered to be invalid, the activation of the control circuit (8) is prevented and the device is thus not released. |
