下旋转塔式起重机负载工作时,为使其塔身不受弯矩,应有合适的塔头几何参数。现对压杆动臂塔式起重机和水平动臂塔式起重机,就其合适的塔头几何参数,分别叙述如下。一、压杆动臂塔式起重机关于压杆动臂塔式起重机塔头的几何参数,《工程机械》1980年第3期本人写的“下旋转压杆式动臂塔式起重机的主要特点和几个重要参数的确定”一文,曾有详细叙述,现将其结论重书于下,以便参考引用。
When working under the load of the rotating tower crane, in order to make the tower body free from bending moments, there should be suitable geometric parameters of the tower head. Now for the pressure boom tower cranes and horizontal boom tower cranes, the appropriate tower head geometry parameters are described below. First, the pressure boom boom tower crane about the pressure boom boom tower crane tower head geometric parameters, “construction machinery” 1980 the third period I wrote “the main characteristics of the lower rotary compression boom tower crane” “The determination of several important parameters” has been described in detail. Now its conclusions are reprinted for reference.
