Load control apparatuses, systems and methods to control a location, orientation, or rotation of a suspended load by imparting thrust vectors to the suspended load or to a structure that holds the load. The load control apparatuses, systems and method may be integrated into a structure that holds a load, such as a rescue litter. The load control apparatuses, systems, and methods may be modular. The modular load control apparatuses, systems, and methods may be secured to a load or to a structure that holds the load.

Disclosed are systems, apparatuses, and methods for a load control system for use on or with respect to a main load bearing line, carrier hook, and or head block of a crane.

A gantry stacker having a spreader for containers and including a locating system arranged on the gantry stacker that determines a position of the gantry stacker. To permit a more precise receiving or depositing of containers in a predefined position in a container terminal, sensors are arranged on the gantry stacker, with the sensors and the locating system being connected to a control unit, and the control unit determines a position of the spreader, of a container to be received or of a deposit site from the position of the gantry stacker using the signals from the sensors.

A container crane has a trolley movable on a cross-member of a gantry. A harness for picking up and setting down a container and at least one laser scanner are arranged on the trolley. The laser scanner captures a depth image which, as a function of a first and a second angle, indicates the distance of object points detected by a laser beam. The captured depth image is evaluated. Based on the object points, objects are detected and their locations are determined. The objects comprise the harness and/or a container picked up by the harness, and further objects. Based on the detected object points, the contour of the harness and/or of the container picked up by the harness is determined. Detection of further objects within regions defined by the contour is suppressed. A control device takes the detected objects and their locations into account for controlling the container crane.

Provided is a dynamic-lift-off determination device capable of quickly performing a dynamic-lift-off determination by a simple method, while suppressing swinging of a load. A dynamic-lift-off determination device C includes: a boom 14 that is configured so as to be freely raised and lowered; a winch 13 that lifts/lowers a suspended load via a wire rope 16; a load-weight measuring means 22 that measures a load weight acting on the boom 14; a rope-length and lifting-speed measuring means 24 that measures the rope length of the wire rope 16; and a control unit 40 that controls the boom 14 and the winch 13 and that determines, when the winch 13 winds up the rope to dynamically lift off the suspended load, the dynamic lift off on the basis of a temporal change in the measured load weight and a temporal change in the measured rope length.

Provided are a crane control system and control method for precisely and quickly positioning a crane at a target position. A control system that includes: a position acquisition unit that successively acquires a current position of a gantry crane; and a travel control unit that is connected to each of a pair of travel devices includes a target line that extends in an X direction in plan view and is bent in a Y direction in accordance with an inclination in the Y direction in a state where the traveling gantry crane is inclined, and the travel control unit carries out a control of making the gantry crane travel by adjusting respective travel speeds of the pair of travel devices based on a travel deviation ΔDt between the target line and the current position of the gantry crane acquired by the position acquisition unit.

Simultaneously oppositely rotating sheaves, or a chain fall, has a two sheaves upon a hexagonal axle. The first sheave receives a first line clockwise and the second sheave receives a second line counterclockwise. Upon turning the axle, the sheaves handle the lines oppositely. A signal unit regulates power delivered from a power unit to at least one motor. The power unit is preferably a battery or alternatively another source. The motor turns a gearbox that engages the axle cooperating with the sheaves. The chain fall includes an anti-two block per line. Preferably, a pulley has two outer plates and two inner plates on stubs with the first line in the center and the two second lines between an inner plate and an outer plate. A first plate and a spaced away second plate contain the components of the invention in compact form for usage by a crane.

Provided is a lifting arrangement configured to facilitate alignment of a load with a wind turbine assembly. The lifting arrangement includes a crane arrangement for hoisting the load to the wind turbine assembly, a tagline arrangement for stabilizing the load during a lifting manoeuvre, a sensor arrangement configured to detect a motion of the wind turbine assembly relative to the load during the lifting manoeuvre, an actuator arrangement for adjusting the position of the load relative to the wind turbine assembly, and a control arrangement for controlling actuators of the actuator arrangement to reduce the detected relative motion. Also provided is a method of aligning a load with a wind turbine assembly.

A container crane control system including: a camera configured to be fixedly mounted to a crane to obtain a series of captured images, a video output configured to provide a video signal including a series of cropped image based on the series of captured images; and a control device configured to, for at least part of the captured images and the respective cropped image, receive an input signal indicating a current height of a load of the crane, wherein the control device is configured to control a position of the respective cropped image within the captured image based on the current height of the load.
