Flat head tower crane with superior performance. Excellent lifting performance, with an 80m arm length and a tip capable of lifting 2.2t and a 75m arm length capable of lifting 3.5t. It has strong adaptability for PC buildings, large bridges, and nuclear power construction. The maximum lifting capacity is 20t, and the maximum lifting speeds are 95m/min, leading the industry. The combination of arm lengths is diverse, with a maximum boom length of 80m, a variable boom length of 2.5m, and a minimum boom length of 30m. There are 21 types of arm length combinations. The maximum independent height is 71.4m, and the tower body can be equipped with standard sections of 2.2m and 2.5m tenons. The 2.5m tenon joint has good rigidity and strong wind resistance, especially suitable for coastal areas with typhoons. The main chord of the standard joint is interchangeable with the 2.2m tenon joint. Safe and reliable with triple protection for lifting capacity and double protection for torque to prevent overloading. The lifting height provides triple protection against collision, while the amplitude provides double protection against collision. Intelligent detection and protection of anti slip hooks in the electronic control system. Control of lifting balance and lifting motor to prevent accidents during lifting operations. The boom pin shaft connection has strong resistance to sudden unloading and accidental collision.
