Benkelman Beam

Model: HM-574
Price: $1,673.00

The HM-574 Benkelman Beam is a simple lever-arm device which measures deflection of flexible pavements under the action of moving wheel loads. The probe beam, supported by a rigid reference beam, measures deflections using its 2.44m (8ft) probe end and a dial indicator at the end of the fulcrum. Deflections measured on a dial indicator are doubled to obtain total pavement deflection. The probe beam is placed between the tires of a test vehicle and deflection is measured as the vehicle passes over the test area. The reference beam has a leveling adjustment to zero the dial indicator. A switchable battery-operated vibrator alerts operator and assures free movement of beam parts during measurements.

The three-piece, anodized, lightweight aluminum beam is 33lb (15kg) net weight for easy portability, and the longest piece is 6.5ft (1.99m). Dial Indicators must be ordered separately.
