Abstract:
A spreader (24) comprises a main frame carrying container connector arrangements configured to engage with a transport container (10); a rotator enabling rotation of the main frame in relation to a crane bracket about a substantially vertical rotation axis (A2); a rotation motor configured to, responsive to a rotation control signal, operate the rotator to rotate the main frame; a rotation detector configured to detect rotation of the main frame in relation to the crane bracket; and a control system configured to, based on a discrepancy between the rotation control signal and a rotation detected by the rotation detector, generate a rotation alert signal.
Abstract:
A spreader for lifting a transport container comprises a main frame (26) suspended in a main frame suspension arrangement (36) to enable translation along a longitudinal axis (L). The main frame (26) is vertically supported by the main frame suspension arrangement (36) along a support line extending between a first support end (68a) and a second support end (68b), and the main frame suspension arrangement (36) carries the weight of a suspension arrangement load comprising the main frame (26), container connector arrangements (28a, 28b), and any container(s) attached to the container connector arrangements (28a, 28b). A detector arrangement is configured to detect if a centre of mass of the suspension arrangement load is positioned at a longitudinal position along the support line which is beyond a limit position.
Abstract:
The present invention relates to a crane monitoring, warning and protection system. The crane monitoring, warning and protection system comprises at least one anemometer (70) for measuring wind movements in the vicinity of a crane and a database on at, a forecast module (60) for collecting and analyzing wind movement data from the at least one anemometer (70) and a database on atmospheric data (80) to predict possible occurrence of a hazard, and a processing unit (40) for monitoring the crane connected to the at least one anemometer (70) and the forecast module (60). The processing unit (40) generates an alert signal based on the prediction from the forecast module (60). Upon detection of a hazard, the processing unit (40) activates a crane lock (30) to stop movement of the crane along a rail direction.
Abstract:
The present innovation relates to warning devices for load transfer operations, particularly for warning personnel working in heavy industrial sites near cranes and their loads. A crane load warning device has a retention unit and pivotally connected signaling unit. The signaling unit has user programmable lateral warning lights, vertical focused beam light and an audio signal. The retention unit has a retractable clamping arm with clamps, adapted to clamp onto load rigging such as a wire sling and retain the warning device on the load. The crane load warning device can be attached to a crane load whilst maintaining a vertical orientation of the focused beam light and prevent accidents by providing audio visual warning signals.
Abstract:
Die Erfindung betrifft ein Verfahren zur Überwachung einer Arbeitsmaschine, insbesondere eines Krans, die aus zwei oder mehreren Einzelelementen für den Arbeitseinsatz gerüstet wird, wobei ein Überwachungsmittel der Arbeitsmaschine ein oder mehrere gerüstete Elemente eindeutig identifiziert und deren Einsatzzeit bestimmt, wobei die bestimmte Einsatzzeit wenigstens eines Elementes zusammen mit Identifikationsinformationen an ein Speichermittel zur Erstellung einer Einsatzhistorie des Elementes übermittelt wird.
Abstract:
A system and method of measurement, identification and analysis of material lifting products using remote monitoring. The method includes designing a lift plan for a load including various equipment and a plurality of legs. A lift sensing and monitoring device is selected for each of the legs and connected thereto. Load data is transmitted from each of the lift sensing and monitoring devices during the lift to a mobile receiving and transmitting device. An alert is generated if any tension value from the load data is greater than capacity.

Abstract:
The present invention relates to a crane (101).The crane (101) has a hoist (113) for performing a lifting operation and a controller (125) for controlling operation of the crane. At least one sensor (127) is provided for detecting the presence of a person in a safety region (129). The controller (125) is configured to inhibit operation of the crane (127) when the sensor (127) detects a person in the safety region (129).The present invention also relates to a crane control system and a method of operating a crane (101).
