A lifting fixture comprises a lifting affordance slidingly coupled to an upper horizontal beam assembly, a lower assembly comprising two spaced-apart horizontal beams defining an intervening gap, and a substantially vertical structural assembly connecting a first end of the upper beam assembly to a first end of the lower assembly. The horizontal beams include arrays of threaded holes for receiving various adapter plates. The first horizontal beam assembly comprises a motor driving a power threaded lead screw engaged to a lifting affordance such as a lifting eye. The motor may be controlled by wireless remote control. The lifting fixture allows lifting of an object stored beneath an overhead obstruction to be manipulated using a crane whose lifting axis is offset to the side of the overhead obstruction.

A crane control system for controlling a plurality of cranes is provided. The crane control system in some embodiments includes a master controller unit, at least one computer readable memory for storing a plurality of tokens, each token from the plurality of tokens associated with a respective crane from the plurality of cranes, and a processing unit responsive to commands inputtable by an operator of the master controller unit to send the commands to individual cranes from the plurality of cranes, wherein the processing unit associates the commands with respective tokens to control the cranes associated with those tokens. The crane control system in some embodiments also includes a processing unit that is responsive to a signal indicative of a synchronization loss to issue a command to bring the plurality of cranes into a safe condition, such as an emergency stop, or a corrective action.

A method for controlling a materials handling and/or construction machine, such as a crane or cable excavator, wherein different control functions are selected on a screen of a controller with a touchscreen function by touching a control function symbol, and respective functional parameters of the selected control function are set. A working region boundary of a working region delimiting function for automatically deactivating and/or slowing down at least one actuator is displayed on the screen together with a display of the materials handling and/or construction machine and/or the work surroundings in the form of a touchscreen display element when the working region boundary is reached and is adjusted by touching and moving the working region boundary on the screen relative to the display of the materials handling and/or construction machine and/or the work surroundings thereof.

Horizontal translation, pendular motion, and or yaw control of a load suspended from a carrier with a suspended load control system, wherein control input to the suspended load control system may be provided through the use of more than one remote pendant.
