The structure of jib crane is a jib suspended on a bracket, which can be driven by a motor to move and rotate horizontally and vertically within a certain range for lifting and carrying heavy objects. The fabrication process is to determine the design scheme, fabricate the bracket, fabricate the jib, install the motor, install the control system, test and debug.

Jib cranes have an overall "floating" function that makes it easy to achieve good balance even when unloaded, and this type of manipulator is widely used because it is lightweight, fast, and economical.

Jib crane belongs to light work intensity crane, is a practical light work station lifting equipment. With high efficiency, energy saving, save trouble, small footprint, easy to operate and maintain and other characteristics. Especially suitable for short distance, frequent use, intensive lifting operations. Mainly by the column, rotating arm, supporting arm and reducer, electric chain hoist, electrical parts and other components.

Cantilever crane contains a curved arm type cantilever crane, fixed column type cantilever crane, mobile cantilever crane, double arm cantilever crane, although they have different names, but they also have common characteristics. For example, the footprint is also small, high efficiency, high reliability in the use of the time, very suitable for short distance lifting and transportation, the use of frequency is also very high, and all can carry out more intensive lifting work.

In the crane industry, semi-gantry cranes are a special type of crane that combines the designs of overhead cranes and motorized gantry cranes. A semi-gantry bridge is supported on one side by an elevated runway, just like an aerial bridge. At the other end of the bridge, the crane is supported on the legs of a semi-gantry, at the end of which trucks run on wheels or wheels with tracks on the floor. In this design, power is typically provided by a power pole and current collector assembly on the elevated runway side of the semi-gantry crane and distributed to the crane trolley via a tow system. SEVENCRANE semi-gantry cranes can be controlled via a wired suspension controller or optional crane radio remote control system.

Container cranes are used in container terminals. Trailers will be shore wall container carrying bridge from the ship unloaded containers transported to the yard or rear, by the container gantry crane stacked up or directly loaded and transported, can accelerate the turnover of the container carrying bridge or other cranes. Can be stacked high 3 to 4 layers, wide 6 rows of containers in the yard, generally with tires, there are also railed.
