ANCHORED CRANE TRACK FOR SEISMIC REGIONS

摘要

material handling facilities. SUBSTANCE: proposed anchored crane track has filled rail support, ties and two rail lines. Concrete anchors with cross ribs are embedded in filled rail support under each rail line along the line, being spaced through three-four ties. Concrete anchors are connected with ties by means of threaded joints of steel bolts. Steel bolts are rigidly fixed in head tee- part of anchors. Pressure plates resting on ties through rubber pads at both sides of each rail are put on steel bolts. EFFECT: provision of crane stability and partial damping of vibrations at earthquakes. 2 cl, 2 dwg
