Problems solved by technology

In this case, due to the low position of the container 105, conventional reach-stacker cranes cannot lift the container
If the extended arm head (that is, the downward extension of the position where the arm head is connected to the professional spreader) is directly used to adapt to this working condition, it will become inconvenient for the front-loading crane to operate in the traditional workplace

Abstract

The invention discloses a crane boom head system which comprises a crane boom head and a hanger connecting structure, and further comprises an expansion device, one end of the expansion device is connected with the crane boom head, and the other end of the expansion device is connected with the hanger connecting structure. The crane boom head system provided by the invention can meet the requirements of a traditional operation site, is also suitable for sites requiring negative angle operation, and meets the operating conditions of sites such as railroad relay stations, barge berths and the like. According to the invention, on the basis of not increasing auxiliary devices such as special hangers and the like, whole vehicle working condition and application range are expanded. The invention further discloses a crane provided with the crane boom head system.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, more specifically, to a jib head system and a crane. Background technique [0002] The reach stacker crane is a telescopic boom container crane with a self-propelled tire chassis, and the purpose of hoisting goods is realized by connecting a spreader to its arm head. The spreader is usually used for lifting containers, and different spreaders can also be replaced according to different goods to achieve the purpose of lifting different goods. [0003] As a special machine for container loading, unloading, stacking and horizontal transportation, reach stacker cranes have the advantages of flexible maneuverability, good stability, and high yard utilization compared with forklifts, and are widely used in docks, ports, warehouses, etc. Lifting and transfer. Products such as combined cranes, steel pipe cranes, log cranes and tiltable bulk material cranes can also be derived on the basis of...
