This flat head tower crane epitomizes superior performance and reliability. Boasting an impressive 80m arm length with a tip capable of lifting 2.2t and a 75m arm length capable of lifting 3.5t, it is engineered for excellence. Its versatility makes it ideal for PC buildings, large bridges, and nuclear power construction. Dominating the industry with a maximum lifting capacity of 20t and lifting speeds up to 95m/min, it stands unmatched. The crane offers a myriad of arm length combinations, featuring a maximum boom length of 80m and a variable boom length of 2.5m, down to a minimum boom length of 30m, totaling 21 different configurations. It achieves an independent height of 71.4m, and the tower body can be outfitted with 2.2m and 2.5m tenon standard sections. The 2.5m tenon joint offers remarkable rigidity and wind resistance, perfect for typhoon-prone coastal areas. The main chord of the standard joint is interchangeable with the 2.2m tenon joint. Safety is paramount with triple protection for lifting capacity and double torque protection to prevent overloading. Triple collision protection for lifting height and double collision protection for amplitude ensure utmost safety. Advanced electronic control systems provide intelligent detection and anti-slip hook protection. The lifting balance control and motor management safeguard against potential lifting operation hazards. Moreover, the boom pin shaft connection is fortified to withstand sudden unloading and accidental collisions.
