Dynamic study of the mechanism of movement of the trolley of a revolving crane mounted on a wall
SCIENTIFIC WORK, 2022Divara bərkidilmiş dönən kran sənaye müəssisələrində, tikinti meydançalarında və başqa yerlərdə yük-boşaltma işlərində geniş istifadə olunur. İş zamanı kranın arabacığının hərəkət mexanizminin qərarlaşmayan hərəkətlər zamanı dinamik yüklərə məruz qalır. Bu zaman dinamik yüklər statik yüklərə nəzərən daha böyük qiymət alır. Həmçinin kranda yük asılarkən

Overhead cranes are widely used when performing reloading operations on closed ones (fig.1) and open warehouses of sea and river ports. Since they are a link in the technological process, the productivity of Port lines depends on their reliable and continuous operation. Overtime and long term operation of metal structures of overhead cranes in the mode

Actin inhibitors block or slow anaphase chromosome movements in crane-fly spermatocytes, but stopping of movement is only temporary; we assumed that cells adapt to loss of actin by switching to mechanism(s) involving only microtubules. To test this, we produced actin-filament-free spindles: we added latrunculin B during prometaphase, 9-80 min before ...
