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.

A wide belt industrial tension tester capable of measuring force from 0-396 lbs (0-180 Kg.), and belt tension from 0-6336 lbs (0-2880 Kg.), on belts to 12" in width. A single setting of the instrument allows an operator to bring belt force/tension to the desired amount.

Recommended for use on 5V-5VX belts and more. Will service 5V-5VX belts through 18 strands, 8V through 11 strands, C-CX through 13 strands, and D belts through 9 strands.

Operation: Follow the steps for the basic WB1-70 model, except that the outer two units do not show belt tension.
  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.
