Opis:
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.

Opis:
The paper contains the designs of modifications of testing devices, which were constructed for the purpose of checking the functional properties of the mechanical pallet fixing lock built by the KOMA – Industry s.r.o. company, which is used for securing pallets with cars in parking houses. The individual testing devices consist of one or two positioning devices, the moveable parts of which are placed perpendicular to each other in the frame of the testing device. A mechanical pallet fixing lock is attached to the moving part of the perpendicular positioning device, and it consists of the following three parts: the body, the pulley holder and a compression coil spring. A plate is attached to the moveable part of the horizontal positioning device and is adapted to receive a pressure force sensor or to engage a mechanical fixation lock or the break of an electromagnetic locking device. The paper contains the description and method of experimentally determined resistance, which is created by the shear friction on contact surface, when inserting or withdrawing the pulley holder tube from the plain bushing of the fixation lock body. Additionally, the paper provides the values of the measured vertical forces, which are generated by the deformed compression spring with a wire of circular cross-section during inserting/withdrawing of the pulley holder tube into/from the fixation lock body. The values obtained from the performed experimental measuring of vertical forces and frictional resistance during the inserting of the pulley holder tube into the plain bushing of the fixation lock body will be used for subsequent checking of the functional properties of pallet fixation locks and will allow determining the optimal position for attaching the pallet fixation locks to stack cell steel beams in the parking house, on which chain conveyers push pallets with cars are parked.

Opis:
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.

Opis:
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.

Opis:
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.
