Recently, it was learned that Shandong Hongda "Tielishi" brand QZ500 large tower crane once again rewarded Russia.
Shandong Hongda Construction Industry Group Co., Ltd. is exporting the Russian "Tielishi" brand QTZ500 tower crane. It is designed and manufactured according to the needs of Russian users. The rated lifting moment is 500 tm, the maximum lifting weight is 25 t, the independent height is 77 m and the maximum height is 322 M. It adopts a large number of high strength steel, light weight, and the bending moment of the tower is small; the lifting adopts intelligent frequency conversion speed control technology, and chooses according to the load. Frequency, impact is small, speed regulation is stable; German Flander reducer with fan is used for hoist reducer, Huawu brake with open brake detection is used for brake, which has high reliability; frequency conversion and eddy current speed regulation control system is used for slewing and amplitude variation, and the starting and braking are stable; Sichuan Jiuhe brand reducer (Manitowoc) is used for slewing and amplitude variation; remote safety monitoring system is installed, which can be used in the office. When the tower crane works under various working conditions, the monitor on the control platform communicates with the mechanism electronically. The driver can input various parameters and monitor the various working conditions of the electrical appliances (gear, current, voltage, frequency equivalent) in real time, and judge whether the work is abnormal at any time. The chip-mounted standard section 2.45m * 2.45m * 5m is adopted to reduce the volume of transportation and storage, and the humanized ramp climbing and rest platform. This type of tower crane has many installation forms, such as walking, fixing, internal climbing and so on.
Shandong Hongda Construction Industry Group Co., Ltd. is the backbone enterprise of construction machinery in China. It has been 30 years since the development and production of tower cranes. The production of large, medium and small series of tower cranes has reached more than 30 models, and its overall technical indicators are in the leading level in China. Tielishi is recognized as a well-known trademark in China. Its products cover all parts of the country and are exported to more than 20 countries in the world.
