Description of Qtz 50 series tower cranes
Q qtz 50 is the smallest overall and most economical of the family of tower cranes used by Dahan construction equipment. Most often it is used as a series of cranes in low-rise construction, construction of shopping centers, sports facilities, administrative and cultural facilities, buildings erected using light construction structures, as well as on larger-scale construction projects in combination with more powerful tower cranes. The reducer of the Qtz 50 tower crane of imported (not Chinese) production ensures smooth running, reliability and durability of its operation. Plc Plc (programmable logic controller) Dah Dahan. This system uses the installed sensors to get the parameters of the crane operation in automatic mode, analyze and predict possible failures in the operation of tower crane systems. The cab with a large impact-resistant viewing glass is equipped with a comfortable seat and a clear control system for the tower crane, which guarantees safety and low fatigue for the crane operator.
Dahan tower cranes has been ranked first in China's industry for the past decades.
"Dahan" R & D, product quality has passed several experiments with strict testing. Dahan has 16 years of production technology and rich experience in quality management. So far, over 100 national crane tower patents have been introduced in already used in order to guarantee the reliability of the quality crane tower and reduce costs, BA Baosteel and wisco, the crane tower is becoming more secure and reliable.
Tower cranes Dahan , whose establishment in the first place started to use the robot welding line. The production line consists of automatic material preparation, Mach maching. All the main parts of the Dahan crane tower using welding robot with the most advanced carbon dioxide emission mixed with argon shielded welding, it has deep synthesis depth, high quality Welding and stable performance. Fully automatic welding robot production line for manufacturing consists of more than 100 welding machines
All parts and components of the Dahan tower crane use trademarks of Intel Corporation. Electrical equipment with Schneider neutralizer, aviation, stainless steel junction box and three hitch control consoles has the functions of low failure rate and easy installation.
The lifting mechanism is provided by leading manufacturer Jiangte engine or Dezhou Shengjian, all with engine oil, free maintenance, high reliability and low maintenance costs.
Brake support uses the Maanshan fangyuan Ro Roth ERDE trademark, twice in data processing mitigation allows for smoother operation and longer tower crane service life.
High-strength bolts adopt marine scale coupler dacromet technology. It may not rust for ten years. Swiss screw thread mounting bolts preload up to 30% compared to traditional bolts. "Derricking".
Lifting, derricking and turning mechanism with complete safety, such as torque, weight restriction. Steel rope broken rope device. The range of design vehicles against loss and breakage of the shaft, such as the device tilt. Adopts Electric overload protection, PLC self-diagnosis system, in convenient for maintenance.
