System for the safe operation of platform lifts of lorries, comprising a lorry with a cargo container, a loading area that can be closed by means of a platform lift as well as a mobile remote control, wherein the platform lift comprises a platform, control electronics and a hydraulic system with a lifting cylinder, a tilt cylinder, hydraulic lines, a hydraulic motor and hydraulic valves, characterized in that the system - comprises a multi-zone localization for determining movement permissions of the platform by means of localization the mobile remote control, comprising at least two short-range sensors for receiving and transmitting signals to and from the mobile remote control, wherein a short-range sensor is arranged on each side of the rear area of the lorry, wherein the short-range sensors are arranged on the opposite sides of the lorry cargo container, and the short-range sensors are selected in such a way that the attenuation of the signal power of the short-range sensors to the lorry side in the directional diagram is at least 6 dB higher than in the opposing direction, and, - where applicable, comprises a sensor package to determine whether the platform is loaded, wherein the sensor package comprises an inertial sensor which is arranged on the platform, and the control electronics are connected to the short-range sensors and, where applicable, are connected to the inertial sensor in order to process the signals received from the sensors (4, 5) in the control electronics, wherein the control electronics are configured in such a way that the multi-zone localization divides the space in and around the lorry into different control zones Z with different movement permissions of the platform by means of localization of the mobile remote control, wherein these zones comprise at least - one first safe zone Z1 for the operator, in which unrestricted operation of the platform is permitted, wherein zone Z1 comprises a maximum distance D1 from at least one short-range sensor, - where applicable, a second zone Z2, which comprises the area of the platform arranged in a horizontal position, as well as the adjacent space to it to the side and rear with a maximum distance D2 from the end of the platform, wherein the zone Z2 does not comprise the zones Z1, Z3 and Z5, - a third zone Z3 as the maximum working area in which limited operation is permitted, wherein the zone Z3 has a maximum distance D3 from at least one short-range sensor, wherein the zone Z3 does not comprise zones Z1, Z2 and Z5, - a fourth zone Z4 comprises everything outside zones Z1, Z2, Z3 and Z5 in which no operation of the platform is permitted, and - a fifth zone Z5, which comprises only the area on the platform in which it is detected, where applicable, by means of a sensor package, whether the platform is loaded or empty, wherein, due to the respective operating zones Z1 to Z5, as well as, where applicable, the current platform angle determined by means of an inertial sensor, the zone-specific, predefined movement permissions of the platform, in particular, its maximum angular speed and angle of inclination cannot be exceeded. - comprises a multi-zone localization for determining movement permissions of the platform by means of localization the mobile remote control, comprising at least two short-range sensors for receiving and transmitting signals to and from the mobile remote control, wherein a short-range sensor is arranged on each side of the rear area of the lorry, wherein the short-range sensors are arranged on the opposite sides of the lorry cargo container, and the short-range sensors are selected in such a way that the attenuation of the signal power of the short-range sensors to the lorry side in the directional diagram is at least 6 dB higher than in the opposing direction, and, - where applicable, comprises a sensor package to determine whether the platform is loaded, wherein the sensor package comprises an inertial sensor which is arranged on the platform, and the control electronics are connected to the short-range sensors and, where applicable, are connected to the inertial sensor in order to process the signals received from the sensors (4, 5) in the control electronics, - one first safe zone Z1 for the operator, in which unrestricted operation of the platform is permitted, wherein zone Z1 comprises a maximum distance D1 from at least one short-range sensor, - where applicable, a second zone Z2, which comprises the area of the platform arranged in a horizontal position, as well as the adjacent space to it to the side and rear with a maximum distance D2 from the end of the platform, wherein the zone Z2 does not comprise the zones Z1, Z3 and Z5, - a third zone Z3 as the maximum working area in which limited operation is permitted, wherein the zone Z3 has a maximum distance D3 from at least one short-range sensor, wherein the zone Z3 does not comprise zones Z1, Z2 and Z5, - a fourth zone Z4 comprises everything outside zones Z1, Z2, Z3 and Z5 in which no operation of the platform is permitted, and - a fifth zone Z5, which comprises only the area on the platform in which it is detected, where applicable, by means of a sensor package, whether the platform is loaded or empty,
