(*) Factory weight setting

1. No.1,2 & 3 have mounting bolts and compression washers included and have a drilled and tapped hole for safety cable or lift eye.
2. Sound produced in decibels - decibel reading taken with vibrator mounted on a 400 lb. steel plate at a distance of 3 ft. (.9m) from dB meter - A scale - slow response. Noise levels may be greater than those listed dpending upon the structure on which the vibrator is mounted. (Caution: Above 85 dB use ear protection.)
3. Centrifugal force lb. = .0000284 x (in. lb.) x RPMsq.
4. N = Newtons = (lb. x 4.4482)
5. To convert in. lb. to Newtonmeter (Nm) = (in. lb. x 4.4482) / 39.37
6. RPM varies with oil flow.
7. Rule of thumb -
   @ 1745 to 4600 RPM - 1 lb. (1 N) of force to 20 lbs. (2.0 kg) material in slope section of bin.
   @ 6000 to 9000 RPM - 1 lb. (1 N) of force to 10 lbs. (1 kg) material in slope section of bin.
8. Oil flow controls speed (RPM). The oil flow needed to maintain speed may vary with temperature and motor wear.
9. Average running pressure is taken with a vibrator mounted on a 400 lb. steel test plate with an oil temperature of 100sF (37.7sC). On the job pressure may vary with the work load and rigidity of the mount.
10. Inlet and outlet ports are marked on the motor - This motor rotates in one direction only.
11. Force outputs listed here are calculated at the RPM listed, but a higher RPM may be acceptable if the vibrator weights are set on a lower setting. You may contact your dealer or the factory for the bearing life at higher speeds. (Note: for models HC3-3500 and HL3-3500, the RPM listed is the maximum RPM for all weight settings).

Specifications

Three styles of mounting make these vibrators extremely versatile.
The Bolt-On style foot (H9-500, HA9-1600, HA4-3300) is used for all permanent applications. The Clamp-On style foot (HL4-3000, HL3-3500) is used for rail car unloading and other temporary applications. The Cradle-Lug style vibrator (HC4-3000, HC3-3500) must be used with one of the brackets listed. Weld-On, Clamp-On, Bolt-On, or Wedge Brackets. The wedge bracket is designed to fit all female brackets commonly supplied on most rail cars and is the preferred method of rail car unloading.
