A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

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 control switch for operating a crane. The control switch includes a first interface designed to transfer signals between the control switch and a control unit of the crane. In order to combine, in particular, the robustness and operating reliability of the control switch desired in industrial use with increased functional scope in a cost-effective way, the control switch is provided with a second interface designed to transfer signals between a mobile terminal and the control switch in order to add functions of the mobile terminal to the functional scope of the control switch.

A concrete/steel structure disassembling apparatus which comprises a triangular or T-shaped housing, and a suspension member is pivotably coupled to the triangular or T-shaped housing, and the suspension facilitates suspension of the triangular or T-shaped housing from a crane. At least a concrete/steel pulverizer apparatus is pivotably supported by the triangular or T-shaped housing, and the concrete/steel pulverizer apparatus comprises a pair of concrete/steel pulverizer arms for engaging with a desired section of a concrete/steel structure and pulverizing the same. The concrete/steel structure disassembling apparatus incorporates its own completely independent power module for supplying hydraulic power to the concrete/steel pulverizer apparatus and controlling operation of the at least one pair of concrete/steel pulverizer arms, and the power module is supported by the triangular or T-shaped housing.

For updating an inventory of objects located in a hoisting area wherein a load is handled by a hoisting appliance equipped with a scanning device and spanning a hoisting area, the inventory including physical data and log data associated with objects and being provided by a supervisory system supervising the hoisting area, a control device: generates a trajectory of the hoisting appliance for navigating through the hoisting area taking in account a time interval and the log data, wherein the trajectory comprises a starting point, a target point and a number of consecutive line segments connecting the starting point and the target point, optimizes the trajectory for allowing a scan of objects associated with old log data during the time interval, executes the optimized trajectory and scanning objects during the optimized trajectory, yielding to scan data related to the scanned objects, and sends the scan data to the supervisory system for updating the inventory with the scan data.

A method and equipment for controlling a lifting device, wherein a main steering direction of the control device used by an operator is selected from at least two options; the impact of the control device on the directions of motion of the lifting device is changed according to the selected main steering direction; and the lifting device is controlled with a control device.
