In order to promote the deep integration of informatization and industrialization, speed up the popularization and application of advanced technology of integration of two modernizations, and guide industrial enterprises to adopt new technology and equipment of integration, Shandong Economic and Information Commission, on the basis of extensive collection and expert evaluation, compiled the first batch of Guidance Catalogue of Key Promotion of Advanced Practical Technology and Equipment of Integration of Two modernizations, and released it on June 14. The "Tielishi" brand QTZ500 tower crane independently developed by the Science and Technology Research Institute of Shandong Hongda Construction Industry Group Co., Ltd. was included in the first batch of "Guidance Catalogue for Key Popularization of Advanced Practical Technology and Equipment for Integration of Industrialization and Diversification" in Shandong Province.
Shandong Hongda "Tielishi" brand QTZ500 tower crane, rated lifting moment 500tm, maximum lifting weight 25t, independent height 77m, maximum height 322m; a large number of high-strength steel, light weight, tower body bending moment force is small; hoisting adopts intelligent frequency conversion speed control technology, according to load selection frequency, impact is small, speed regulation is stable; hoisting reducer adopts German fan Flander reducer, brake mining. Huawu brake with open brake detection has high reliability; frequency conversion and eddy current speed control system are used to control rotation and amplitude variation, and the starting and braking are stable; Sichuan Jiuhe Brand Reducer (Manitowoc) is used for rotation and amplitude variation; remote safety monitoring system is installed, which can real-time understand the working conditions of tower crane in the office, and communication between monitor and mechanism is realized on the control platform, and the driver can be real-time. When input various parameters and monitor various working conditions of electrical appliances (gear, current, voltage, frequency equivalents), determine whether the work is abnormal at any time; use chip-mounted standard section 2.45m * 2.45m * 5m to reduce the volume of transportation and storage; humanized ramp and rest platform. Its main functions are vertical transportation of heavy objects and short distance horizontal transportation in construction site. There are many kinds of installation forms, such as walking, fixing, internal climbing, to meet the needs of different customers.
