Two-Stage Marker Detection–Localization Network for Bridge-Erecting Machine Hoisting Alignment [PDF]
To tackle the challenges of complex construction environment interference (e.g., lighting variations, occlusion, and marker contamination) and the demand for high-precision alignment during the hoisting process of bridge-erecting machines, this paper ...

The Technical and Economic Aspects of Using DC or AC Motors in the Drive of Hoisting Machines [PDF]
A hoisting machine is one of the main components of an underground mine process line. The drive systems currently used in these machines are based on direct current, synchronous, or induction (AC) motors. Power electronic converters are used to power and

Pattern recognition of rigid hoist guides based on support vector machine [PDF]
In order to evaluate the serviceable condition of rigid hoist guides and recognize their status patterns, vibration and angle signals were collected from an test-rig which can simulate different sorts of defects. Characteristic parameters by which status patterns can be judged were selected and designed.

Machine vision–based measurement approach for transverse vibrations of moving hoisting vertical ropes in mine hoists using edge location [PDF]
Hoisting vertical rope is a continuum of one-dimensional movement during operation of hoist, and there are no appropriate ways to measure its vibration displacement at present. In this paper, a non-contact and unmarked machine vision measurement method is proposed for measuring the transverse vibration displacement of hoisting vertical ropes.

Investigative study of hoisting machine loading when using frequency converter controlling systems
The paper deals with the impact of the controlling system adjustment on the level of the dynamic loads operating on the hoisting machine parts during the period of the non-steady motion. The impact of the operating regime of the hoisting machine generalized mechanism on the consistency of operation and the variation of the parameters of the mechanism ...
