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.

Container crane development trend: rated lifting capacity has increased exponentially. The rated lifting capacity under the spreader has gradually increased from 30.5t to 61t, and now it has reached 65t. The outreach is getting bigger and bigger. With the continuous large-scale container ships, the ship width has increased from the 3rd generation of Panama container ships 13 rows to the current super-Panama ship 14 to 17 rows of boxes

Ako všetci vieme, hmotnosť kontajnerov potrebuje na prepravu nejaké špeciálne vybavenie a zrodil sa kontajnerový portálový žeriav. Môžu naraz jazdiť v kontajneri a zdvíhať a spúšťať ciele podľa rôznych potrieb. Vďaka nízkemu ťažisku , ľahko ovládateľný, aby sa predišlo odchýlke ťažiska, kontajnerový portálový žeriav zvyčajne používa strop.
