A connecting arrangement by which an electric load, which can be displaced in at least one direction of travel in relation to a feeder device, is supplied, by a cable, with electrical energy and/or data. The feeder device has at least one connection member for connecting to a corresponding connecting element of a cable carried by the electric load. An energy-supply system supplies the electric load. A simplified automatic connection of the cable to the feeder device by a connecting arrangement has a manipulator for connecting the connecting element to the connection member. A related energy-supply system has such a connecting arrangement and a related method has the following steps: a) positioning the connecting element in relation to the feeder device, b) using a manipulator to grip the connecting element and/or the cable, and c) using the manipulator to connect the connecting element to the connection member.

The present invention provides an automatic deviation correction control method for a hoisting system, comprising the following steps: obtaining a lateral displacement X and an advancing included angle α generated by the deflection of the hoisting system; when the lateral displacement X is not 0 and the advancing included angle α is not 0, determining whether the lateral displacement X and the advancing included angle α satisfy a preset condition; if the lateral displacement X and the advancing included angle α do not satisfy the preset condition, controlling the hoisting system to correct the deviation toward a center line; and if the lateral displacement X and the advancing included angle α satisfy the preset condition, controlling the hoisting system to correct the deviation toward the center line in a reverse direction. The automatic deviation correction control method for a hoisting system provided by the present invention can implement automatic deviation correction, thereby implementing the automatic deviation control of the hoisting system, and then effectively reducing the workload of a driver during work.

The present disclosure provides an intelligent port control system and related systems and apparatuses, capable of achieving fully automated ship loading and unloading. The intelligent port control system includes: a scheduling center system configured to determine a ship loading plan based on ship information, container information, and shore crane apparatus information, and generate a ship berthing task, a ship loading task, and a container distribution task based on the ship loading plan, for transmitting to a ship control system of a target ship, a shore crane control system of a target shore crane apparatus, and a warehouse management system of a warehouse center, respectively.

A lift system for a rotor blade of a wind turbine includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle and the tip end supports a tip cradle. The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted uptower, the rotor blade can experience an asymmetric loading. Accordingly, the lift system also includes a variable airflow assembly coupled to tip end of the lifting device. The variable airflow assembly includes at least one surface moveable between a plurality of positions having varying resistances so as to counteract the asymmetric loading.
