QTZ63 Variable Frequency Tower Crane

  The QTZ63C tower crane is a reinforced tower crane designed to meet standards such as GB/T50311 “Tower Cranes” and GB5144 “Safety Regulations for Tower Cranes.” With a rated lifting moment of 63 t·m and a lifting capacity of 6 tons, the TC5013 is a best-selling model in the tower crane series, enjoying significant demand both domestically and internationally. with a lifting capacity of 6 tons. The TC5013 is a best-selling model in the tower crane series, enjoying significant demand both domestically and internationally. This crane features a variable-pole speed control system for the hoisting mechanism and a variable-frequency speed control system for the slewing mechanism. The luffing mechanism incorporates a planetary gear reducer with an integrated drum. The electrical control system utilizes imported components, while safety protection devices are either mechanical or mechatronic products, ensuring comprehensive and reliable performance. Capable of fixed, traveling, anchored, and internal climbing configurations, this crane meets the diverse construction needs of urban mid-to-high-rise buildings, industrial plants, power station dams, bridges, and other structures.

Variable Frequency Drive QTZ63 (5013) Technical Specifications 

【Hoisting Mechanism】:

Rotary Mechanism:

【Variable-Angle Mechanism】:

【Upper and Lower Supports】:

     The upper support is mounted on the slewing bearing and connected to its inner ring. The lower support is a box-shaped support for the non-rotating section of the crane. Its upper surface is fitted with the outer gear ring of the slewing bearing. The lower support is bolted to the outer ring of the slewing bearing, enabling relative rotational movement between the upper and lower supports via the slewing mechanism. The upper support connects to the rotating tower body above, while the lower support connects to the standard tower sections below.

【Rotary Limit Switch】:

【Tower Top】

    The top of the tower is a sloping cone, with its upper end connected to the lifting arm and counterweight arm via tie rods to maintain the horizontal alignment of both arms. Its lower end is secured with four pins to

    The rotating tower body connection features a work platform and pulley system at the top of the tower to facilitate the installation of the boom tie rods and counterweight boom tie rods.

【Driver's Cab】

   The cab serves as the operator's workstation for controlling the tower crane, fixed to the right side of the rotating tower body. The indicator lights and control handles of the integrated control console are positioned on both sides of the operator's seat, offering convenient operation and a wide field of view.

   The cab electrical control box is located at the rear of the cab, housing the main circuit breaker, lighting circuit breakers, auxiliary circuit breakers, and other devices.

【Load Limiters】:

【Electrical Control System and Safety Devices】 :

      The QTZ63 electronic control system employs a state-of-the-art PLC + variable frequency drive (VFD) control approach, significantly enhancing system reliability, operability, stability, and machine efficiency. The incorporation of a VFD enables stepless speed regulation for the slewing mechanism, substantially improving overall equipment stability. This results in markedly enhanced positioning performance and higher operational efficiency.

     The electrical control components of this system are globally sourced from leading manufacturers such as OMRON, Yaskawa, Schneider Electric (TE), and Taiwan's Mingwei. This global procurement strategy significantly reduces the failure rate of the electrical control system, providing effective assurance for enhancing users' production efficiency.  Comprehensive and reliable safety devices are included, such as: lifting height limiters, slewing limiters, and multifunctional limiters for lifting moment, load capacity, and trolley span. Additionally, electrical safety devices like anemometers and obstruction lights, as well as mechanical safety devices such as trolley shaft break protection and traction rope break anti-runaway protection, are incorporated.
