塔式起重机可分俯仰臂架型与水平臂架型两种。在日本,俯仰臂架型占多数,而欧美则相反,几乎都是水平臂架型塔式起重机。其理由是,在日本,对建筑物具有抗震要求,大部分都是钢骨架构成的建筑,每个部件往往比较重。因此就倾向于要求具有比较大的起重能力,一般以考虑俯仰臂架有利。在欧美一些国家,低中层建筑几乎以砖或混凝土为主,即所谓混凝土建筑占多数。这类建筑以提升混凝土作业为重点,须重视满足轻负荷高频率作
The tower crane can be divided into two types: the luffing jib type and the horizontal jib type. In Japan, the luffing jib type accounts for the majority, while in Europe and the United States, on the contrary, almost all horizontal boom type tower cranes. The reason is that in Japan, earthquake resistance is required for buildings, and most of them are steel skeleton structures, and each part is often heavy. Therefore, it tends to be required to have a relatively large lifting capacity, and it is generally advantageous to consider the luffing jib. In some countries in Europe and America, low-rise buildings are mostly brick or concrete, which is the so-called concrete construction. This type of building is focused on upgrading concrete operations, and attention must be paid to satisfying light-load high-frequency operations.
