This paper describes a question of evaluation necessity of bridge cranes using the method of limit deformation state and oscillation damping. The solution was performed by means of theoretical analysis and an experimental verification at the selected bridge crane. The final result sounds that in the case of a correct strength computing of given bridge crane, it is not necessary to also check deformation and damping of oscillation as well.

This article deals with a dynamic simulation of the movement and fall of persons working at a height, using the rope belaying system. The input data, which are necessary for a created simulation model, were obtained from experimental measurements realised from the concrete belaying system. The simulation analyses were performed for three different values of the rope pre-load level. Consequently, the outputs from the simulations presented in this article were applied in a real design proposal of the rope anchoring arrangement for a horizontal belaying system.

This article describes a technical proposal of anchoring determined for a horizontal belaying system, which was developed to increase the safety of crane operators and maintenance staff in their movements and work at heights. This belaying system can be installed either on the common, already existing footbridge of the overhead travelling crane or on the crane track. Loading of the steel wire rope was investigated by the simulation figurines during various assumed loading regimes. The figurines were attached to the rope belaying system by means of the standard personal protective equipment and the calculation process was realised using the non-linear dynamic FEM analysis.

This article describes the design of a horizontal rope system for increasing the safety of work and movement on a specific device operating in height. This system is designed to be installed on a conventional existing crane footbridge or crane track structure and this system enables a free pass along the rope, without unclamp of spring hook on prolongation rope. The calculation was made by non-linear dynamic FEM analysis.
