A set of lift controls may be configured to determine the load on the motor (112) by a vehicle of an unknown weight during operation at a standard lift speed and use such information to determine a potential speed that the motor may raise the vehicle at while staying within safe operational levels for the motor. One or more of a magnitude of electrical power drawn, a pressure generating by a hydraulic lifting, or a sensed vehicle weight may be used to provide an indication of load on the motor and/or a higher potential speed.

The present disclosure relates to mobile radiographic inspection systems and lifting devices for mobile radiographic inspection systems, including those, for example, in the field of radiographic detection of large objects such as containers. In one illustrative implementation, the present disclosure describes a lifting device for a mobile radiographic inspection system, the device comprising a driving motor and at least two screw lifters, wherein the driving motor is connected to each of the screw lifters via a transmission, and a lower end of a lifting rod of the screw lifter is configured to connect with a radiographic inspection device. In implementations, the lifting device may further comprise a mounting assembly, which is adapted to connect the lifting device to a vehicle body of the mobile radiographic inspection system.

Conventional vehicle lifts typically operate at a standard speed that is statically configured for the system, which may result in vehicles that are below the weight rating for the lift being raised at the standard speed while the lift motor is capable of safely raising at greater speeds. A set of lift controls may be configured to determine the load on the motor by a vehicle of an unknown weight during operation at a standard lift speed and use such information to determine a potential speed that the motor may raise the vehicle at while staying within safe operational levels for the motor. One or more of a magnitude of electrical power drawn, a pressure generated by a hydraulic lifting, or a sensed vehicle weight may be used to provide an indication of load on the motor and/or a higher potential speed.
