The 7030 tower crane 16t tower crane features stable operation and reliable management due to the adoption of various advanced technologies. It is configured with diverse devices like the hydraulic self-propelling device, frequency converting slewing device and a series of reliable safety devices like hoisting height limiter, slewing range limiter and multifunctional limiter. It is thus easy for this heavy lifting equipment to control the hoisting capacity, load moment and trolley traveling range more precisely. Additionally, multiple electric safety devices such as anemoscopes and obstacle lights effectively prevent the breaking of trolley axles and wire ropes.
