Cable Tray Support bracket fabrication and installation

Cable Tray Support bracket fabrication and installation

1、support bracket fabrication

Hesheng Group ‘s high strength polymer whiskers flame retardant cable tray can use the finished plastic pipe hoop or metal support and hanger bracket. If the metal support is used, anti-corrosion measures should be taken according to the design, and a rubber pad should be placed on the contact surface of the bridge and the metal support.According to the different laying methods of the cable tray, the fixed support method is also different accordingly.  Hesheng is a professional cable tray factory or cable tray supplier  which can supply all kinds of cable tray in differenct materials.

(1) The cable tray is laid horizontally along the beam bottom:

This is a common way of laying the cable tray. The cable support bracket is composed of the main column and the cross arms. The main column is fixed by steel expansion bolts on the beam or roof, the cross arms is mounted on the main column by angle steel, and the cable tray is laid on the horizontal beam.

(2) The cable tray is laid horizontally along the wall

When the cable trunking  or wireway cable tray is laid horizontally along the wall, the support is composed of column, column base and cross arm.When the wall is a concrete wall, the column base is generally embedded according to the cable tray height to be installed in civil construction; when the wall is a brick masonry, the column can be directly fixed on the wall by metal expansion bolts instead of the column base.

(3) The cable tray or cable trough is laid vertically along the shaft

The cable tray is laid vertically along the vertical shaft. The support can be directly fixed on the shaft wall by metal expansion bolts, and then fastened on the steel strut channel or unistrut with fixed swallow tail buckle.

2、Support bracket installation

Before the installation of the polymer cable tray or ladder cable tray or perforated cable tray or wire mesh cable tray or wire cable tray , use the direction of the bullet line to mark the position of the fixed point.The bracket spacing for horizontal mounting is 1.5~3m and vertical mounting is not more than 2m.According to the bearing load of the support, select the corresponding metal expansion bolt. After the metal expansion bolt is inserted into the fixing point, use the nut and the corresponding washers to fix the support directly to the metal expansion bolt.When installing the bracket at the same time, pay attention to the net distance between the cable tray and other pipes and adjust the height and position of the bracket appropriately.
