某高層工程塔吊選用方案
根據(jù)B標(biāo)段工程特點(diǎn)，在該工程的垂直運(yùn)輸機(jī)械的選用上，我公司優(yōu)先考慮了采用由建設(shè)部長(zhǎng)沙建設(shè)機(jī)械研究院設(shè)計(jì)的QTZ63（5013）型與南京第一建筑機(jī)械廠生產(chǎn)的QTZ60A型兩種新型自升附著式建筑塔式起重機(jī)。QTZ63（5013）型與QTZ60A型起重機(jī)均為水平臂架，小車變幅，上回轉(zhuǎn)自升式多用途塔式起重機(jī)。其中QTZ63（5013）型臂長(zhǎng)為50M，最大起重量為6噸,自重62T（100M）；QTZ60A型臂長(zhǎng)為45M，最大起重量為6噸，自重53.8T(100M)。此兩款機(jī)械主要的共同特點(diǎn)如下：
1、上部采用液壓自頂升，利用自身進(jìn)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
