Wire Rope Sheave Friction Effects
When a takeup weight is offset to the side of a conveyor, a wire rope is commonly routed from the take-up weight through a series of sheaves to the take-up carriage. The friction developed from a series of wire rope sheaves can effect the actual belt tension at the take-up carriage. Through real-time testing the actual tension on a takeup carriage was recorded with data acquisition using an int...
متن کاملStudy on Wire Rope Brace Design Method of Prestressed Braced Steel Moment Frame
To study the design method of sectional area and initial tension of wire rope brace of the prestressed braced steel moment frame structure system, theoretical analysis of this structure system is conducted in this paper. The lateral stiffness formula is derived. It reveals the lateral stiffness is related to the lateral stiffness of bare steel moment frame, story height, the distance between co...
متن کاملElectromagnetic Method of Testing the Wire Rope Vis-a-vis Calibration of Defects
This paper presents the details about calibration of defects; wear and broken wires by electromagnetic method in a wire rope used for hoisting of men and material in mines, aerial rope ways, lifts etc. Electromagnetic method of testing the wire ropes consists of powerful magnets to magnetize the wire rope, and sensors to detect the defects in the wire ropes. A typical instrument used in the inv...
متن کاملCondition Monitoring of Rope-less Elevator Braking System Based on Wavelet Denoising
The rope-less elevator driven by Permanent Magnet Linear Synchronous Motor (PMLSM) is a new technology for high-rise buildings. In the practical operation, PMLSM inevitably encounters various kinds of turbulences which directly affect the rope-less elevator’s operation. The braking system is important for rope-less elevator safe and steady operation. Usually, the ordinary inspections are not ab...
