[0002] A man-carrying hanging basket used on a crane is composed of a hanging basket main body bearing mechanism, a crane adaptive suspension mechanism, a safety protection and fall arrest mechanism. The suspension mechanism is first rigidly connected to the crane boom through a hook base, then locked with the top lifting lugs of the hanging basket main body bearing mechanism via symmetric lifting points, and the built-in horizontal leveling device is started at the same time to ensure the main body bearing mechanism remains in a horizontal state. After that, the suspension mechanism transmits the power of the crane lifting system to the main body bearing mechanism to provide traction for its lifting. After obtaining power through the suspension mechanism, the main body bearing mechanism carries personnel and tools to complete vertical lifting. Meanwhile, as the crane boom luffs, the suspension mechanism drives the main body bearing mechanism to adjust the operation position synchronously, so that the platform is always in a stable state for carrying personnel and performing operations.

[0003] In the prior art, when a man-carrying hanging basket is lifting, workers need to wear a full-body safety harness for protection. With the development of the market, safety lanyards have emerged, which can further protect workers during the operation of the crane. A safety lanyard is added on the basis of wearing a full-body safety harness, which further guarantees the safety of workers.

[0004] However, for the above arrangement of adding a safety lanyard on the basis of wearing a full-body safety harness, one end of the safety lanyard needs to be installed on the frame of the man-carrying hanging basket, and the other end is buckled on the worker. When the safety lanyard is in use, it needs to be taken out separately and then installed. When the safety lanyard needs to be stored, there is no space on the man-carrying hanging basket for storing the safety lanyard. Therefore, it is necessary to design a man-carrying hanging basket for aerial operation cranes to solve the above problems. Contents of the Utility Model
