WJKC rail pressure is JBT1696-2010 GB LHC

A, LHC1 rail pressure device characteristics: 1, LHC1 rail pressure is mainly used for fixed steel crane beam with a horizontal guide wheel track of fixed and flexible large-tonnage crane hook track. 2, no need to crane beam drilling, crane beam flange welded directly to the board. 3, LHC1 rail pressure is under lateral force to withstand the maximum horizontal guide wheel acts as 135K N; maximum lateral force under LHC2 rail pressure is subjected to horizontal guide wheel role 220KN; LHC3 rail pressure is subjected to horizontal guide wheel The maximum lateral force under the action of 400KN. Two, LHC1 rail pressure selection of note: with horizontal guide wheel crane end to the full-length track laying works with composite rubber plate, with no horizontal guide wheels may lay. Three, LHC1 rail pressure Mounting: 1, the base, the base can be used three grooved surface and press the center rail position fix, the position of the crane beam centerline tolerance disabilities 1.00mm; 2, T-bolts, and place goes to the rail direction; 3, adjustment plate, and there facing the groove on; 4, followed by installation of the platen, washers, spring washers and nuts; 5, move wedge adjustment plate, rail pressure control to adjust the vertical and direction of the rail position, when the pressure plate and the bottom rail of closely packed, and then tighten the nut. Bolt tightening torque LHC1, LHC2 of 256N m, LHC3 to 423N m;.. 6, in order to reduce stress can take a symmetrical weld seam, reverse welding, stitch welding and other measures; 7, should be considered in the design and construction of fixed base plate for cranes Deflection change.
