在捷克斯洛伐克共和国小型机械化施工过程中采用的一个典型实例,住宅改造工程使用了通用窗式提升起重机OYM125-轻型携带式装置,可在水平和垂直方向运输建筑材料,其通用性范围为:它可以装在窗洞内,通过它可以把各种材料提升到建筑物上;也可以固定在支撑立柱上,把立柱装在上下两层楼之间(如图1);或者固定在建筑物的外脚手架上(如图2)。 OYM125型提升机由以下几部分组成:悬臂,装在悬臂上的提升机构,此提升机构由蜗轮传动卷筒,带有制动器的电动机组成;可转动的立柱,带有滑轮的可折(伸缩)的挺杆;配有将提
In a typical example of a small mechanized construction process in the Czechoslovak Republic, the housing renovation project uses a universal window lift crane OYM125 – a lightweight portable device that can transport building materials horizontally and vertically. Its versatility ranges from: Installed in the window hole, through which it can lift various materials to the building; it can also be fixed on the supporting column, and the column can be installed between the upper and lower two floors (as shown in Figure 1); or it can be fixed on the outer scaffolding of the building. On (Figure 2). The OYM125 hoist consists of the following parts: Cantilever, lifting mechanism mounted on the cantilever. This lifting mechanism is composed of a worm-drive reel and a motor with brake. The rotatable column can be folded with a pulley. The tappet;
