五、下回转塔机的安装架设下回转塔机的安装架设分拼装式和整体拖运快装式两大类。拼装式是指在工地上,用一个个部件拼装起来的塔机。其中,如果用它自带的设备来完成安装就是自装式,用外来起重机协助安装叫他装式,或叫城市型塔机,这一类下回转塔机的安装有点类似上回转塔机的安装。而整体拖运快装式,本来在工厂已组装成一台起重机,只是把它按行驶拖运状态折叠起来,拖到工地后,只要设法就位,再利用专用的安装设施,很快就可把它架设起来,故称为快装式,其架设步骤就是怎么从拖运状态变为工作状态的操作过程,不涉及部件。下面重点介绍拼装式下回转塔机的安装。
Fifth, the installation of the next turret crane installation Set up turret crane installation Erection-type assembly and the overall hauling fast-mounted two categories. Assembled refers to the site, with one by one assembled tower crane. Among them, if it comes with its own equipment to complete the installation is self-loading, using an external crane to assist him to install the installation called him, or city tower crane, this type of lower turret machine installation similar to the upper turret machine installation. The overall haul-off type, originally in the factory has been assembled into a crane, just put it by towing state folded up, dragged to the site, as long as managed to put in place, re-use of special installation facilities, can quickly put It is erected, so called quick-loading, the erection step is how to move from the haul state to the working state of the operation, does not involve parts. The following focuses on the assembly of the next tower crane installation.
