Used Yongmao Stt153 Construction Tower Crane with Video Inspection

Our flat head tower crane is engineered for exceptional performance and versatility. Boasting an impressive lifting capacity, it comes with an 80m arm length capable of lifting 2.2t and a 75m arm length that can handle 3.5t. Designed for demanding environments, this crane excels in PC building projects, large bridges, and nuclear power construction. With a maximum lifting ability of 20t and industry-leading lifting speeds of up to 95m/min, it stands at the forefront of crane technology. Its modular arm lengths offer unparalleled flexibility, ranging from a full 80m to a minimum of 30m, with 21 different length configurations. The crane's maximum independent height reaches 71.4m, and it features standard section tenons of 2.2m and 2.5m, the latter providing enhanced rigidity and superior wind resistance, ideal for coastal areas prone to typhoons. The interchangeable main chord ensures operational efficiency. Safety is paramount with triple lifting capacity protection and double torque protection to prevent overloading. Lifting height and amplitude protections add further safety measures. Advanced electronic control systems include intelligent anti-slip hook detection and protection, as well as balanced lifting control to mitigate the risk of accidents. The robust boom pin shaft connection offers exceptional resilience against sudden unloading and accidental impacts.
