Features of QTZ125 (HS5023) 10T Tower Crane

QTZ125 Tower Crane is a new type of construction tower equipment that is researched and designed by Institute of Building Mechanization of China Academy of Building Research based on large formwork construction technology. It has the following characteristics:

1) Lifting multiplying factor switchover automatically, without operator's intervention.
2) Ahead of all domestic competitors, we are the first manufacture to adopt lifting rope verticality limit mechanism, which decreases the lifting rope vertical angle under free load lifting mode, and highly improves the tower crane steering performance.
3) Our tower sections are exchangeable with the POTAIN H3/36B tower sections, which provide our customers more conveniences.
4) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be under no stress at lifting surface other than uniaxial stress, and moreover, it gets rid of the stress peak. It greatly improves the fatigue safety performance of lifting boom.
5) Adopts VVVF stepless speed variation device for lifting, radius changing and slewing mechanisms, to make sure it works steadily and effectively, it also lowers the maintenance cost.
6) The equipment adopts to use non-contact computer control system, which provides the high reliability and full functions to avoid drivers' miss-operation.
