Consolidating a placement is a job measured in reach and in head size, not in horsepower: the head has to fit between the bar and the shaft has to get it to the bottom of the form. The UM-Series ships as one assembly, motor and shaft and head together, so what a crew orders is a working vibrator rather than a power source that still needs a shaft matched to it. Eight builds cover four head diameters across three shaft lengths, which is what lets one range serve slab work and deep wall pours from the same shelf.

The motor case is aluminium to keep the unit light on a shoulder through a pour, the handle is vibration dampened so the operator's hands are not taking what the head is putting into the concrete, and the whole unit is double insulated, which is why no ground connection is required at the outlet. A sealed fan keeps the cement dust that hangs over a placement from being pulled through the motor. This is built for the concrete crews consolidating placements at a slump of three or more, and for the contractor who wants a shelf of ready-to-run units rather than a box of shafts.

Common Applications

  • Consolidating slab and footing placements
  • Consolidating wall and column forms where the shaft has to reach the bottom
  • Working concrete around congested reinforcement with a small-diameter head
  • General concrete placement at a slump of 3 in or more

Selection Notes

  • Head diameter sets both the amplitude and the space the head needs; the 0.90 in head is the one that goes into congested bar, and the 1.50 in head carries the largest amplitude in the range
  • Shaft length is what decides reach; the 3.2 ft builds are for slab work and the 8.2 ft builds for anything the operator has to reach down into
  • The 0.90 in and 1.25 in heads are offered on the 8.2 ft shaft only, so a short-shaft requirement narrows the choice to the 1.10 in and 1.50 in heads
