Tower Crane QTZ50
Features of the Hammerhead Tower Crane
1) We produce the self-erecting tower crane by using internationally advanced technology and an innovative top-slewing design for a reliable performance. Our construction tower cranes come in four models: traveling, attached, stationary and inside-climbing.
2) The steel structure of the construction machine is made from high grade Ansteel and Baosteel Q345B products (well-known Chinese steel businesses), and the strength level meets European Fe510 standards.
3) The electronic control uses advanced frequency conversion control technology and a RCV/PLC stepless frequency speed electronic control system. Contactors are from Schneider in France.
4) The topkit tower crane features a horizontal arm support, trolley, top slewing, and hydraulic jacking. Its maximum jib length is 48/50m and its moment of force is 630kN.m. The crane has a free standing height of 35m, though with attachments it can reach up to 120m.
With its simple structure, stable performance, and excellent quality, the self-erecting crane is well-received among small to mid-sized construction businesses. Our affordable cranes are equipped with advanced safety devices and are easy to maintain.
