In general, a tower crane refers to a construction machine capable of hoisting, swinging, and traversing motions installed at a height around a building or structure. The tower crane is close to a building because it can be lifted up and its work range is wide. In particular, it is widely used in dense high-rise construction work in large cities, and recently, various kinds of tower cranes for plant construction, steel tower construction or port unloading have been used.

The tower crane is divided into a jib type and a hammer head type according to the shape of the top portion. The house type installs a rotating frame at the top of the tower and attaches the house to perform the rotary motion or the linear movement of the trolley to lift or lower the cargo. The hammer head type is provided with a swivel frame at the top of the tower, and a boom is installed to balance the left and right to horizontally move the load. The capacity is usually expressed as a lift load, divided into smaller than 3 tons, medium to less than 5 tons, and large to 5 tons or more. The working range is mostly 30m or more, and the self-supporting height is determined by the strength of the tower, which ranges from 18 to 30m.

Looking at the structure of the tower crane, it is a mast (Mast) is assembled on the foundation anchor formed on the installation ground, the length is usually 2-3 times longer than the general mast, and the overall silly weight because the mast is installed at the bottom of the tower crane This is a structure that serves as a pillar to support the tower crane to the upper side of the base mast (Basic Mast) is firmly manufactured and fixed to the ground as large as a pin of a member having a unit length of about 3 ~ 5M Alternatively, the installation height can be increased by connecting with a connection bolt. The mast is an angle or box type welding structure using mostly high-strength steel, or a mast using an open angle and H-Beam, and a hydraulic cylinder and a hydraulic motor lift up to one side of the mast. It is used to increase the height of the mast as a device. Telescoping cage formed by operating the hydraulic cylinder several times to insert a new mast into the space secured by the cylinder stroke to increase the height, and the upper part of the mast turning device and the lower part of the main jib. The cab is installed at the position where the work position and the turning radius display are easily visible, and the cab head is installed to support the tie bar between the main jib and the counter jib on the upper part of the cab. (Cat Head) and the cantilever-shaped structure centered on the pivot axis connected from the head, the lifting capacity is determined according to the length of the jib, that is, the turning radius. The truss structure is designed to reduce the wind load and weight, and the main jib with a side pulley for checking trolley ropes and a trolley winch inside the truss, and for hoisting operations to and from the main jib. Trolley, a traverse device that determines the turning radius, a hook, a hoisting device for hoisting by hanging up and down by a wire rope lowered from the trolley, and a tower crane on the opposite side of the main jib.
