Cable Tray the installation method is: 2 suspension rods+1 cross arm, the suspension rods are perpendicular to the horizontal plane, the top of the suspension rods is connected and fixed with expansion bolts or other fixing parts, the bottom of the suspension rods is connected to the cross arm, and the cross arm is parallel to the bottom of the bridge. The weight of the bridge is transferred to the support through the cross arm and suspension rod.

Arm mounting bracket is generally used as a support for horizontal cable trays. The support arm and the bridge are also in a horizontal position, fixed to the wall, beam or column with bolts, and the bridge is then connected and fixed to the support arm.

Vertical installation bracket, this type of bracket is used for the installation of vertical and vertical cable trays, and is generally used in vertical shafts. The bracket is fixed on the wall of the vertical shaft, and the weight of the bridge is mainly concentrated on the connection surface between the bridge and the bracket.

For Hot dip Galvanized cable tray, determine the diameter, material, and length of the suspension rod and cross arm, and then calculate the weight of a pair of brackets based on the unit weight table. The installation spacing of Slotted cable tray is generally 1.5-2m. Knowing the total length of the bridge frame can determine the number of brackets.

Arm support bracket, as above, determine the relevant parameters of the arm components, calculate the individual installation quantity and installation quantity.

Vertical brackets, which occupy a relatively small proportion of space, are generally not included in the calculation.
