Tower cranes are divided into two categories: upper slewing tower cranes and lower slewing tower cranes. Among them, the bearing capacity of the former is higher than that of the latter. In many construction sites, what we have seen is the upper-slewing-type tower crane with upper jacking and joint height. According to whether it can be moved, it is divided into: walking type and fixed type. The tower body of the fixed tower crane is fixed and cannot be rotated. It is installed on the monolithic concrete foundation, or installed on the strip or X-shaped concrete foundation. The walking type can be divided into four types: crawler type, automobile type, tire type and track type. In the construction of the house, the fixed type is generally used. According to its luffing method, it can be divided into two types: horizontal boom trolley luffing and boom luffing; according to its installation form, it can be divided into three types: self-elevating type, integral quick disassembly and assembly type. The most widely used are lower slewing, quick disassembly, rail-mounted tower cranes and self-elevating tower cranes that can be used for four purposes (rail-mounted, fixed, attached and internal climbing).
