Introducing the Flat Head Construction Crane Yongmao Stt153, a marvel of engineering designed for unparalleled lifting needs. This tower crane boasts exceptional performance with an impressive 80m arm length, capable of handling up to 2.2t at the tip, and a 75m arm length that can lift up to 3.5t. Engineered to adapt seamlessly to PC buildings, large bridges, and nuclear power construction, its maximum lifting capacity of 20t and industry-leading lifting speeds of 95m/min set it apart from the competition. Versatility is at the core of this crane, offering a diverse range of arm length combinations, from a maximum boom length of 80m to variable lengths in 2.5m increments, down to a minimum boom length of 30m, with 21 possible configurations. Standing independently at a height of 71.4m, the tower body is equipped with standard sections of 2.2m and 2.5m tenons. The robust 2.5m tenon joint excels in rigidity and wind resistance, making it ideal for typhoon-prone coastal regions. Notably, the main chord of the standard joint is interchangeable between the 2.2m and 2.5m tenons. Safety remains paramount with triple protection for lifting capacity and double protection for torque, preventing overloading. The crane also ensures operational safety with triple collision protection for lifting height and double collision protection for amplitude. Cutting-edge intelligent detection and anti-slip hook protection, alongside balanced lifting control and a secure motor system, prevent accidents. Additionally, the boom pin shaft connection is engineered to withstand sudden unloading and accidental impacts.
