The Selection of Cable Bridge Load

October 23rd, 2014

best roll forming machines

The deck floor roll forming machine facts seem to be a big question for people. What is deck floor roll forming machine?

When choosing a cable bridge load level, cable tray work uniformly distributed load should not be greater than the selected uniformly distributed load rating of the cable bridge load level, if the actual span cable tray of steam-water is not equal to 2 m, the uniformly distributed load work shall meet the requirements. You will know how to make a passive purlin roll forming machine well. In steam-water various components and meet the corresponding load conditions, the size should be with a straight run of tray, ladder, curved series matching.

Choose according to the bending radius of cable tray
In the choice of cable tray bending or tilt, guide device, should not be less than the minimum allowable bending radius in cable tray, which is strongly different with deck floor roll forming machine facts.

Main problems of design drawings in material statistics:
1) items. Some statistical bracket material statistics through only a partial, bent on some statistics. Some material table is without a steam-water altogether. For engineering general contracting company, the consequences of a missing item is in the project quotation stage lead to roll forming machine china price low, and in the project implementation stage always purchasing department and suppliers to sign the supplementary contract, thus resulting in a loss of general contracting company profits.

2) Wrong. The reason is that many designers for some concept is not clear, some count steam-water bending, as attachments, some put the cover as main materials. In fact, carrier includes the pass-through of cable tray and bent on two parts. Cable tray attachment includes all kinds of connection plate, cover plate, plate, pressure plate, terminal board, led under parts, fasteners, etc. Accessories in the material are not shown in the table, by the supplier with goods supply, which cost into the unit price part of the bracket. Projects do not need to separate the supplier offer.

3) a big deviation statistics, the number is usually less. Do you know roof panel roll forming machine and glazed tile roll forming machine ? Then how to compare accurate statistics of cable tray in the engineering quotation material? In general, the straight part of the bracket can consider the allowance of 1% ~ 2%, the bending part is direct statistical quantity. Bridge length divided by the average column spacing (outdoor column span generally take 6 m, indoor column span usually take 3 m), post number, increased by 2% ~ 4% allowance. And bridge length divided by the average spacing of steam-water, get the number of steam-water, consider 1% ~ 2% allowances.

All in all, deck floor roll forming machine facts should get more attention as metal roll forming machine is significant in many fields.
