Hoists, platforms and davits are described as well as methods of securing same to telecommunication and other towers. The hoists, platforms and davits may be secured to the towers on a temporary basis using clamps. The clamps may include brackets and cables. The cables may be attached to the brackets, may wrap around the outer surface/perimeter of the tower pole/leg and may use tension to keep the bracket in place.

The invention relates to a method for crane configuration and crane assembly on the basis of an online portal, which holds at least one database with a plurality of standard crane configurations or is connected to the same, with an interface for the user access to the online portal, wherein a crane user virtually composes their individual crane configuration from a plurality of standard configurations and the individual crane configuration is stored on the online portal, wherein at least one further database of the online portal, or an externally connected database, holds assembly information about the stored individual crane configuration, the online portal filters the assembly information relevant in relation to the stored crane configuration and provides it for retrieval by an assembly team.

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.

Working equipment system includes a working equipment, a control unit, a monitoring unit, and a processing unit. The monitoring unit is configured to receive a first data set including predefined equipment data, a second data set including operation data based on sensor signals, a unique identifier for the working equipment, and a time stamp for the second data set. The processing unit is configured to calculate a time series of wear indicator values based on the stored first and second data sets, to estimate a predicted lifetime of the working equipment by extrapolating the indicator values, to compare the predicted lifetime with a target lifetime, and to select an operation mode in dependence of the comparison such that the predicted lifetime corresponds to the target lifetime. The processing unit is configured to transmit the selected operation mode to the control unit that is configured to apply the selected operation mode.

A tower crane includes a tower on which is pivotally mounted a boom displaceable between a lowered position and a raised position. The crane is configurable between a service configuration in which the boom is controlled in rotation and a weather vane configuration in which the boom is in the raised position and is released in rotation on the tower to allow orientation in the direction of the wind. A wind load system is mounted on the boom and is adjustable between a retracted shape in the service configuration providing a reduced surface exposed to the wind, and a deployed shape in the weather vane configuration providing an extended surface exposed to the wind. The wind load system is configured to move from the retracted shape to the deployed shape under the effect of its own weight alone (i.e., under gravity) when the boom is raised.
