Telex ELECTRO-VOICE X-Line TM Xvbp Structural Ratings, Xvbp Pull-UpBar Structural-StrengthRatings

Xvbp Pull-Up Bar Structural-Strength Ratings:

The working-load structural-strength ratings for the Xvbp pull-up bar are shown in Figure 18. The structural ratings are independent of the angle of pull in the front-to-back direction; however, the Xvpb is only rated for use for side-to-side pull angles of a maximum of ±5°, as shown in Figure 18.

A pull-up assembly is only necessary when the front rigging chains (Xvsg, Xvsl and Xvsd) go slack because gravity will not permit the cabinets to hang with the required vertical angles. The pull-up assembly must only be pulled back until the front chains are taut. Additional pull-up force can result in excessive forces in the rigging, or can result in load shifts between the front and back cabinet rigging hardware, the grid, or the hoist motors used to suspend the array. It is the responsibility of the user to make sure that an excessive pull-up force has not been applied.
