DJ-type large-span cable tray can be divided into ladder type, tray type and trough type, represented by T. P. C respectively.
Ladder-type cable tray features good ventilation performance, yet not dust-proof or anti-interference. The trough-type and tray-type cable trays have dust-proof and anti-interference performance.
The Support spacing ≤ 6mm, orders can be accepted when the span> 6mm
For the actual load performance of trough type, tray type and ladder type, refer to the figure below
The cover weight of trough type, tray type and ladder type cable tray is to be calculated separately, B-type cover needs to be widened by 60mm
