Method for monitoring at least one crane

Abstract

The invention relates to a method for monitoring at least one crane, preferably two or more cranes, in particular rotary tower cranes, at a construction site, wherein one or more optical detection means are provided, and a collision monitoring unit analyzes the acquired optical data in order to recognize a potential collision between at least one crane and another crane and / or any other interfering edge.

Description

technical field [0001] The invention relates to a method of monitoring two or more cranes, in particular rotating tower cranes, on a construction site. Background technique [0002] Operation of the crane and control of the hook with or without a suspended load is usually performed by a crane operator in the crane cabin, on the operator's platform or on the ground in the crane's working area. An optimal overview of the construction site is guaranteed from the crane cockpit; however, the distance between the crane operator and the hook is often so great that precise movement of the load to be placed or the hook is difficult. Furthermore, it often happens that the hook is located in an area where it cannot be seen or can only be seen in a limited way by the crane operator. For example, when the hook falls behind the edge of a building blocking the direct line of sight from the crane cab to the load. In these cases, instructions are usually given by a second person.

Problems solved by technology

Especially with multiple cranes on a construction site, the probability of such a shutdown scenario is not small, and cutting power to all the cranes (ie not just the ones with collision risk) would result in a huge impact on the work operations on the construction site. interference

This in turn makes crane operators more reluctant to accept the system

[0006] Since deformations of the load-supporting structure or possible swaying of the hoisting ropes that occur during the movement of the crane cannot usually be identified via data exchange on the interface, with these systems only the position of the load or the movement of the load in a rigid state can be identified

In addition, collision risks can only be identified between cranes equipped with the corresponding ACS

Imminent collisions between the crane and other objects on the construction site such as vehicles, buildings, components or even people moving around may not be detected or recognized
