Aspects of the present disclosure are directed toward apparatuses, systems, and methods for releasably connecting a first beam to a second beam. The apparatuses, systems, and methods may include a locking pin arranged on the first beam and configured to actuate between an unlocked position and a locked position and an arm coupled to the locking pin and extending parallel therewith. The apparatuses, systems, and methods may also include a sleeve arranged on the second beam and configured to receive the locking pin in the locked position to releasably secure the first beam to the second beam.

A system and method for determining the load in a material handling system is disclosed. The load weight detection system measures torque at four operating conditions both at constant speed and during acceleration. The level of torque generated by the motor under each of these operating conditions is stored in the motor drive. The motor drive also receives a signal corresponding to the speed of the hoist motor. Based on the measured torque, as well as the expected torque at no load and at rated load for the measured speed, the motor drive then determines the load present on the hoist. In some systems, two or more hoists are required to operate in tandem to lift a load. Each motor drive determines the weight of the load supported by its respective hoist motor and determines a total weight of the load based on the weights determined by each motor drive.

A collapsible modular building is constructed from at least two building modules that are joined together to form the building. Each building module is constructed to be configured in either a collapsed or erect position. In the collapsed position, each module is individually transported to a site by trailer. Once offloaded, the modules are joined together to form the building, this joining together of the modules can be done while the modules are in the collapsed position or in the erect position.

A device for controlling a swinging of a load suspended from a motorized slidable element is described. The controlling device includes a control unit and an inertial platform. The control unit is provided with means to measure and control the speed of the motorized slidable element and is able to process the values representative of the inclination angle of the cable with respect to the vertical to calculate and to impart control actions in order to dynamically control the speed of the motorized slidable element as a function of a desired inclination angle of the cable with respect to the vertical.

A workstation having a cantilevered crane system that includes one or more cantilevered header assemblies, with each cantilevered header assembly including an upright column and a horizontally oriented header, with the header extending from the column with a free end distal from the column. The headers support a pair of runway rails, with at least one bridge rail movably mounted to the runway rails and supporting a moveable hoist. The cantilevered crane system defines a workstation area bounded by the columns and headers, with the workstation area including an open side adjacent the free ends of the headers.

The shoe derailment device for use in derailing a conductor shoe assembly of a bridge crane from a conductor rail assembly generally has a wedge head provided at a longitudinal end of a body made of an electrically insulating material, the shoe derailment device being securable to the conductor rail assembly in a derailment position in which the shoe derailment device is positioned outside an operating zone of the bridge crane, with the wedge head facing the operating zone in a manner that if the conductor shoe assembly is moved outside the operating zone, into the area occupied by the shoe derailment device, the conductor shoe assembly is derailed from the conductor rail assembly as the conductor shoe assembly engages the wedge head and is maintained in a derailed state by the electrically insulating material when the conductor shoe assembly is engaged with the body.

A crane, such as a bridge crane or gantry crane, having at least one horizontally extending crane girder, which is designed as a lattice girder having a plurality of braces and on which a crane trolley having a lifting device can be moved. At least some of the braces are planiform, and each of the planiform braces has a flat main surface, which extends transversely to a longitudinal direction of the crane girder. On each longitudinal side of the braces, a first cut-out and a second cut-out are provided in the main surfaces. The longitudinal sides of at least some of the planiform braces are free of edge bends at least between the first and second cutouts.

A method for optimizing a model used in real time by an antisway function for the transport of a load by a hoisting appliance, including a gantry able to move along a first axis and a trolley able to move along a second axis, wherein, when transported, the load presents a first sway along the first axis and a second sway along the second axis. The model represents the theorical sway of the load over time, including a first curve representing a first sway, a second curve representing a second sway, and a third curve representing a third sway being a vector of the first sway and the second sway. A control device determines a first remarkable point for the first curve or the second curve depending on the torque of the gantry or the trolley when one of the gantry and the trolley is accelerating, determines a second remarkable point for the first curve or the second curve depending on the torque of the gantry or the trolley when one of the gantry and the trolley is stopped, determines a first remarkable point or the second remarkable point for the third curve depending on a load measurement or the torque of the hoist mechanism when the gantry and the trolley are moving at a steady speed, and synchronizes the model with at least one of the remarkable points.
