An aid system for a wrecker adapted to perform a lifting operation of an object having a weight, the wrecker comprising an extendable boom wherein the extendable boom is adapted to perform the lifting operation through which the wrecker either hauls or lifts the object. The aid system comprises: sensors mounted to the wrecker adapted to collect intrinsic information associated with the wrecker and extrinsic information on the interaction of the wrecker with the operating environment or on the environment in which the lifting operation is performed; a processing unit adapted to collect and process data collected from the sensors to generate dynamic load chart data; and a display for displaying a graphical representation based on the dynamic load chart data, comprising a depiction of the wrecker and of a limit of an operating condition of the wrecker.

A personal safety system for lifting material or supporting person therefrom includes a base and a mast rotatably coupled to the base. The mast has a plurality of mast sections that telescope relative to each other along an axis such that the mast is movable into and between a lowered configuration and an extended configuration. A jib is coupled to the mast and a cable is coupled to the jib such that a cable is configured to couple to the material or the person such that the system is capable of lifting the material or supporting the person. An attachment device coupled to the base is configured to permit a vehicle to couple to the system via the attachment device.

Disclosed are an integral lifting system and lifting method for assembled members. The integral lifting system includes fixing mechanisms and more than four vertical stand columns. The four vertical stand columns are located at four corners of a building, the building is located in a region encircled by the vertical stand columns, a transverse rail beam is disposed between every two vertical stand columns, one end of the transverse rail beam is mounted at the top of one vertical stand column, and the other end is mounted on the top of the other stand column. The transverse rail beam is provided with an operation trolley, a jib crane is disposed on an upper surface of the operation trolley, and a lifting mechanical arm is disposed on an outer side surface of the operation trolley. A hydraulic jacking mechanism is disposed at the bottoms of the vertical stand columns.

A computer-controlled mobile crane is disclosed herein, comprising a column which is rotatable around its vertical axis, a hydraulically actuated primary arm, a hydraulically actuated secondary arm, an attachment point to which a gripping assembly is attached. The components are actuated by a hydraulic control unit controlled by a computer control unit and corresponding software that generates an internal coordinate system on the basis sensors mounted on the crane and an optical measuring unit. The crane is capable of automatically using the gripping assembly to transport a load from an initial point to and end point where the load should be deposited while avoiding one or more obstacles in the path of travel of the gripping assembly and the load.
