[Chai Jin cable tray to recommend the star product - Bridge] checking the formula: Q = q1 + q2 using the formula: q1 - Cable uniform load (layers of uniform load of maximum value) (kN / m2) trough cable tray, uniformly distributed load is a tray, ladder or cable tray load; q2-- consider cable laying or maintenance, the person's weight equivalent uniform load (kN / m2) cable tray, q2 value Calculation of cable trays offer, people generally based on the weight of p = 90kg dollars. Said the concentrated load and uniform load bending moment 2 by Maximum bending moment equal conditions shown in translation: Let pι / 4 = q2ι2 / 8 则 q2 = 2p / ι∵P = 90kg∴q2 = 180 / ι where: P --1 people load (kg) ι - 1 support points spacing (maximum value if the fulcrum distance range) (m) q2--1 human equivalent uniform load (kg / m) based on the preliminary determine the bridge models, specifications and fulcrum distance, consult the manufacturer of the sample data, cross-check the spacing and bridge models, until meet the load requirement.
