A crane (10) includes a carrier unit (20) having a chassis (22), tires (24) connected to the chassis, a carrier deck (26), and outrigger legs (28). A superstructure (30) is mounted on the carrier unit, the superstructure comprising a telescopic boom (38). A slope sensor (80) is operably connected to the carrier unit and is configured to detect pitch and/or roll of the carrier unit during the lifting operation. The crane further comprises a system (50) for monitoring the load lifted by the telescopic boom. The system is configured to: determine a current load lifted by the telescopic boom; receiving pitch and/or roll information of the carrier unit from the gradient sensor; adjusting the coordinates of the crane in the coordinate system based on the pitch and/or roll information; determining a transformed operating radius using the adjusted coordinates; and comparing the lifted load with the rated capacity at the transformed operating radius. 一种起重机(10)包括承载器单元(20)，该承载器单元(20)具有底盘(22)、连接到底盘的轮胎(24)、承载器甲板(26)以及外伸支腿
