某高層工程塔吊選用方案
根據B標段工程特點，在該工程的垂直運輸機械的選用上，我公司優先考慮了采用由建設部長沙建設機械研究院設計的QTZ63（5013）型與南京第一建筑機械廠生產的QTZ60A型兩種新型自升附著式建筑塔式起重機。QTZ63（5013）型與QTZ60A型起重機均為水平臂架，小車變幅，上回轉自升式多用途塔式起重機。其中QTZ63（5013）型臂長為50M，最大起重量為6噸,自重62T（100M）；QTZ60A型臂長為45M，最大起重量為6噸，自重53.8T(100M)。此兩款機械主要的共同特點如下：
1、上部采用液壓自頂升，利用自身進行增加或
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
