某高层工程塔吊选用方案

根据B标段工程特点，在该工程的垂直运输机械的选用上，我公司优先考虑了采用由建设部长沙建设机械研究院设计的QTZ63（5013）型与南京第一建筑机械厂生产的QTZ60A型两种新型自升附着式建筑塔式起重机。QTZ63（5013）型与QTZ60A型起重机均为水平臂架，小车变幅，上回转自升式多用途塔式起重机。其中QTZ63（5013）型臂长为50M，最大起重量为6吨,自重62T（100M）；QTZ60A型臂长为45M，最大起重量为6吨，自重53.8T(100M)。此两款机械主要的共同特点如下：
1、上部采用液压自顶升，利用自身进行增加或
Selection of a high-level engineering programs Tower Crane

Lot B project according to the characteristics of the project in the selection of mechanical vertical transportation, I give priority to the use of the company by the Ministry of Construction of Changsha Construction Machinery Research Institute design QTZ63 (5013) based with the Nanjing Construction Machinery Plant produced the first type QTZ60A Since the rise of two new tower crane attachment architecture. QTZ63 (5013) are the type and level of QTZ60A crane jib, trolley, on the back transferred from lift multi-purpose tower crane. One QTZ63 (5013)-arm length of 50M, the maximum lifting capacity of 6 tons, Weight 62T (100M); QTZ60A-arm length of 45M, the maximum lifting capacity of 6 tons, Weight 53.8T (100M). The two main common characteristics of machine are as follows:
1, the upper hydraulic top-up, increased use itself or
