Failure analysis of a mine hoist rope

Engineering Failure Analysis, 1997
Abstract An extensive investigation was carried out to determine the cause of the early retirement of an in-service hoist rope. The rope was retired earlier than expected because it met the criteria for removal based on the number and distribution of wire breaks.

Hybrid-hoists for ultra deep-level mines

1999 IEEE Africon. 5th Africon Conference in Africa (Cat. No.99CH36342), 2003
Hybrid-hoists have been proposed as a possible solution for ultra deep-level hoists. The hybrid hoist consists of a combination of a conventional hoist and a linear motor. Instead of the entire load being supported by the hoisting rope, the linear motor will take up most of the work during times when peak stresses would usually be placed on the rope ...

Vision-based 2D Vibration Displacement Measurement of Hoisting Vertical Rope in Mine Hoist

Proceedings of the 2020 3rd International Conference on Artificial Intelligence and Pattern Recognition, 2020
In this paper, a non-contact, unmarked computer vision measurement method is presented and applied to measure the two-dimensional (2D) vibration displacement of hoisting vertical ropes. In this method, the primary work is to perform camera calibration of monocular vision using a neural network (NN) model.

Fatigue Life Analysis of Mine Hoist Drum

Advanced Materials Research, 2014
This article is based on a certain type of hoist drum, Moreover, we make the stress and mode analysis for the drum, and make preliminary check on it. Then find the position of the weak section, we calculate the force in each stage of hoisting system and draw force-timing load spectrum,we translate it into stress function of weak link.

Uncertainty analysis and time-dependent reliability estimation for the main shaft device of a mine hoist

Mechanics based design of structures and machines, 2020
The main shaft device (MSD) is a key component of the mine hoisting system. During lifting, vibration of the system will cause dynamic tension of wire rope at both ends, resulting in the complex stress state at the critical location of the MSD and thus ...

A New Electric Mine Hoist at Butte, Montana

Transactions of the American Institute of Electrical Engineers, 1917
A description of equipment in connection with a recent Ilgner-Ward Leonard hoist installation at the Elm Orlu Mining Company, Butte, Montana. This installation is one of the two largest of this type in operation in this country. Complete data on two sets of tests; the first conducted to analyze a typical day's run and the second to determine efficiency
