上旋自装固定式塔机是长沙建筑机械研究所,针对我国当前绝大多数地区和城镇,在6～8层大楼施工建设中,仍然使用卷扬机和龙门架或井架这一现实,为改变这一落后状况,适应住房改革形势发展的需要而设计的一种简单适用,经济实惠的新型小塔机系列,目前该系列包括三个规格:QT16、QT20、QT25 。由于该塔机注重了我国当前绝大多数中小建筑企业的基本要求,深入调查了材料和配件的供应现实,参数选择比较合理,深受全国中小企业的欢迎。为了进一步推广该项技术成果,在此特作如下介绍:
The upper-mounted self-installed fixed tower crane is the Changsha Institute of Construction Machinery. In view of the fact that most of the regions and towns in China are currently under construction, 6- to 8-story building construction still uses winches and gantry or derrick to change this reality. An outdated condition that adapts to the needs of the development of the housing reform and is designed to be a simple, economical and affordable new small tower crane series. At present, the series consists of three specifications: QT16, QT20, and QT25. As the tower crane pays attention to the basic requirements of the vast majority of small and medium-sized construction companies in China, in-depth investigation of the supply of materials and accessories, the choice of parameters is reasonable, and is welcomed by small and medium-sized enterprises nationwide. In order to further promote this technical achievement, we hereby make special introduction as follows:
