(*) Factory weight setting
- No.1,2 & 3 have mounting bolts and compression washers included and have a drilled and tapped hole for safety cable or lift eye.
- 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.)
Centrifugal force lb. = .0000284 x (in. lb.) x RPMsq. - N = Newtons = (lb. x 4.4482)
- To convert in. lb. to Newtonmeter (Nm) = (in. lb. x 4.4482) / 39.37
- RPM varies with oil flow.
- 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. - Oil flow controls speed (RPM). The oil flow needed to maintain speed may vary with temperature and motor wear.
- 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.
- Inlet and outlet ports are marked on the motor – This motor rotates in one direction only.
- 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.
