QTZ80/45 Dual-use machine (Tower Crane with Concrete Pump)
QTZ80/45 dual-use tower crane lifting fabric characteristics:
· New combination of design, changes in the structure to become part of lifting, the fabric of dual-use tower crane.
· Superior performance of the stepless speed regulating agencies.
Double drawbars static set of rigid structure Boom, the largest of 56 m.
· Unique hoisting rope sag limiter to ensure that the boom rotating through the performance, for domestic first.
· Automatically hook conversion rate, the auxiliary operations quickly and easily.
· new concept of closed-end still inline with the sliding roof or roof beam or system design, a fundamental solution to the high drop tower and the safety issues, give you a completely assured.
· Unique structure of the plate connected to greatly shorten the manufacturing process line, the cost has doubled decline in strength and intensity substantial increase in welding.
· Accurate positioning of the body movement limit.
· High precision and high repeat accuracy of torque limiter, from the weight limitation.
· Performance over most of the national standard.
