How to find spanner size from bolt diameter

Following formula are used to calculate spanner size – For bolt size upto M14 . Spanner Size = ( Bolt Size * 1.5 ) + 1. Example for M12 bolt, Spanner Size = ( Bolt Size * 1.5 ) + 1 = ( 12 * 1.5 ) + 1 = 18 + 1 = 19

Rail transport

Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks.In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run.Tracks usually consist of steel …

Belt Conveyor Dynamic Characteristics and Influential …

This paper uses the Kelvin-Voigt viscoelastic model to establish the continuous dynamic equations for tail hammer tension belt conveyors. The viscoelastic continuity equations are solved using the generalized coordinate method. We analyze various factors influencing longitudinal vibration of the belt conveyor by simulation and propose a control strategy to limit the vibration. …

Longwall mining

Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was …
