This does not seam to be a complicated process to select a slewing bearing for the machine. Whether it is a crane, aerial platform, concrete pump or another arm, the principles are same. https://lnkd.in/empN2uvu

B4SH21-280A bevel/right angle gearbox is especially designed Steel Plant Lifting operation, replacement of Flender B4Sh21.  it is mainly used for the casting cranes and ladle cranes; the air breather is facing downwards, eliminating the filter in the air breather but keeping the venting hole design. This design can provent the dust entering into the gearbox, while the air breather with filter is easy to be blocked. #lifting #ladlecrane #castingcrane #crane

#china #factory #crane www.bw-crane.com Bridge crane structure Bridge: it is composed of two main beams, two end beams, platform, guardrail and other parts. There are two structural forms: box and truss. Crane running mechanism: it is composed of motor, brake, speed regulator, coupling, transmission shaft angular bearing box, wheel, etc. Lifting trolley: it is composed of trolley frame, hoist structure and trolley running mechanism. The lifting structure of bridge crane is composed of motor, brake, transmission shaft, coupling, reducer, drum, fixed pulley block and steel wire rope. Divided into single brake and double brake.

Continuously welded rail lines During our Steel 101 workshop at SDI on June 11, Barry Schneider of SDI spoke to us and one of things he was proud of is SDI's capacity to make and ship ¼ mile long rail sections -- that's right a continuous rail 1/4 mile long.  They have a special train (where the rail can slide back and forth as the train goes around corners) that is capable of handling these long rails and by making such long sections in their mill they save a lot of welding work in the field. This left me with two questions.  How is rail welding together in the field and, why doesn’t welded rail buckle when the temperature changes.  The typical clickety-clack that rains make came from the sound of wheels rolling over expansion joints.  These joints were gaps placed at frequent intervals where the rail could slide a bit as it expanded/contracted with changes in temperature.  These joints had a problem however, each time a wheel went over them these joints (and the wheels) wore a bit and over time the rails had to be replaced.  Welded rail solves the wear problem but where does the expansion go? Well thanks to the internet now I know – here are two interesting youtube videos that explain how welded railroad rails work.  It’s obvious from the welding video that longer rail sections save a lot of time and expense. https://lnkd.in/e3tArQvr https://lnkd.in/eQPKY5ib

Full threaded rods are common, readily available fasteners that are used in multiple construction applications. Rods are continuously threaded from one end to the other and are frequently referred to as fully threaded rods, redi rod, TFL rod (Thread Full Length), ATR (All thread rod) and a variety of other names and acronyms. #fastener #bolt #nut #cupheadscrew #Stainlesssteel #screwmachine #screw 🌍 https://buff.ly/3TYv18u
