Ladder-type trays are used for laying power and control cables in the open air, inside buildings and structures. The sections of the trays of the horizontal track should be interconnected by entering one into the other and fixing by means of a bolted connection. Fastening to the supporting structures must be carried out using a bolted connection. The main characteristics and designations of the trays are presented in the table 1.
Table 1 – Ladder trays
|Tray designation||Sizes, mm||Description|
|Width, mm||Length, mm||Useful length, mm|
|NL-20||180||2000||1905||Pan elements welded joint. Coating – primer, PF enamel.|
|NL-К-20||180||2000||1905||The connection of the elements of the tray is riveted. Galvanized sheet.|
By agreement with the customer, NL trays can be equipped with turns, contractions, branches and swivel joints for turning the trunk in a vertical plane. It is allowed to change the coating of trays and workpiece materials in agreement with the customer.
