A method comprising obtaining data from one or more lidars that are installed beneath a trolley comprised in a gantry crane such that the one or more lidars provide a field of view that enables detection of a spreader and a load that is located beneath the spreader, determining, based on the obtained data, a position of the spreader comprised in the gantry crane and configured to be moved by the trolley, and monitoring the environment around the spreader during loading or unloading the load to which the spreader is capable of gripping to.

The invention relates to a method of monitoring at least one crane, preferably two or more cranes, in particular revolving tower cranes, on a construction site, wherein one or more optical detection means are provided, and wherein a collision monitoring unit analyzes the recorded optical data to recognize a possible collision between at least one crane and one further crane and/or another projecting edge.

A method for controlling a boom of a crane in proximity of obstacles at a worksite by defining a forbidden volume is disclosed. In the method a distance from the boom to an outer surface of the forbidden volume is determined and a computing device limits movement of the boom based on the distance from the boom to the outer surface of the forbidden volume to avoid entering the forbidden volume with the boom while the crane is in operation.

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.

A ceiling transport vehicle includes an obstacle detecting portion fixed to a main body portion at a location that is above an article supported by a vertically movable member located at a transport purpose position. The obstacle detection portion is within an area in which the article exists in plan view such that a direction in which detection light, etc., is emitted is tilted outward of the article. When vertically moving the vertically movable member between the transport purpose position and the transfer purpose position, the controller is configured not to determine presence of an obstacle based on detected information from the obstacle detecting portion while the vertically movable member is located in a subject range, and is configured to determine presence of an obstacle while it is not located in the subject range.

An aerial work platform with protection device of electronic sensing type includes: a vehicle, a telescopic transmission component pivotably installed on the vehicle and an operation platform connected to a distal end of the telescopic transmission component. The operation platform comprises a bottom plate, a circular fence disposed on a perimeter of the bottom plate and a control panel installed on the circular fence; the control panel has a barrier formed on its perimeter, the barrier comprises two side bars located at two lateral sides of the control panel, a protection device of electronic sensing type electrically connected with the control panel is disposed on the barrier, and the protection device of electronic sensing type comprises an optical transmitter and an optical receiver which cooperate with each other and are faced towards each other.

A method for controlling a crane component of a tower crane in proximity of obstacles at a worksite by defining a forbidden volume is disclosed. In the method a distance from the crane component to an outer surface of the forbidden volume is determined and a computing device limits movement of the crane component based on the distance from the crane component to the outer surface of the forbidden volume to avoid entering the forbidden volume with the crane component while the crane is in operation. The crane component is one or more of a boom and a hook block.

The present disclosure relates to a method for real time monitoring of the current status of a construction site having one or more work machines, wherein a monitoring means installed at least one work machine monitors the environment of the work machine in real time and generates corresponding monitoring data, with the generated monitoring data being transmitted by the monitoring means to at least one processing unit for a real time evaluation of the current construction site status.

The present invention relates to a crane (101). The crane (101) has a hoist (113), movable in at least one lateral direction (X, Y), for performing a lifting operation. A controller (125) is provided for controlling lateral movement of the hoist (113). An imaging sensor (127) is provided for detecting a person in a defined safety region (145, 147). The controller (125) is configured to inhibit operation of the crane (101) when the imaging sensor (127) detects a person in said safety region (145, 147). The invention also relates to a control system for a crane (101) and a related method.

A transport system including a plurality of transport vehicles is provided. Each of the plurality of transport vehicles includes: a distance detecting portion configured to detect a distance D to a preceding transport vehicle, which is another transport vehicle traveling in front of the corresponding transport vehicle; a signal transmitting portion capable of transmitting a start signal to a subsequent transport vehicle, which is another transport vehicle traveling behind the corresponding transport vehicle; and a signal receiving portion capable of receiving the start signal that is transmitted from the preceding transport vehicle. Each of the plurality of transport vehicles is configured to transmit, when starting to travel, the start signal using the signal transmitting portion, to start to travel upon receiving the start signal from the preceding transport vehicle using the signal receiving portion, and to stop when the distance D to the preceding transport vehicle that is detected by the distance detecting portion is equal to or smaller than a set distance TH1.
