Effect of Operational Condition Changes on the Durability of the Rope for Pusher of Circular Wagon Tipper

Article discusses the pusher wagons in transhipment complex. In terms of the reliability of this device appears to be the weakest link in the transhipment of bulk substrates operated rotary tilter because of its design causes increased wear of the rope. The mode of handling the rope through the properties is an ideal solution for transport of the wagons, which led to finding ways to extend its life. This contribution is proposing a design method for a possible modifications of the pusher with an expected minimum costs and there are calculated the load characteristics of the rope before and after adjustment of the device.

LOCKING THE MOVEMENT OF PERSONS ON THE BRIDGE CRANE

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.
