Industrial Wide Belt Tension Tester
These testers are intended for INDUSTRIAL situations where:
- Belt tensions reach 6000 pounds...
- Belt widths reach 12 inches...

Need to measure tension in that big belt?
- It's EASY! -
The AWI and WB-170 product lines have you covered!

Guaranteed accurate readings.

Functions in much the same manner as the basic WB-170, except it services belts to 12" in width, and has a force range of 0-297 lbs (0-135 Kg.), and corresponding belt tension range of 0-4752 lbs (0-2160 Kg.).

  1. Study belt manufacturer's manual to determine recommended force and tension ranges for the specific belt being tested.
  2. Clamp instrument anywhere along the belt, preferably centered, and insure that the 1/8" bar (below the belt) is located between cogs.
  3. Simultaneously tighten eye-bolts until desired force is indicated on the center unit or desired belt tension shows on the two outside plunger rods.
  4. Tighten (or loosen) belt until the top of the belt is located halfway up the sighting holes.

At this point, you have achieved proper belt tension.
