Description:
Dam vibrator- Mass concrete compaction for biggest granulation
- Variable mounting possibilities
Damvibrator
Hydraulic internal vibrators for VMH-150 are especially suitablefor mass concrete compaction of biggest granulation (max. Ø approx.250mm) because of their high centrifugal forces. All thesecomponents are carefully mated together and provide therefore along life and a high reliability with high power, which isnecessary for this hard application. The vibrators are operated bythe hydraulic system of the carrier vehicle.
Unit for mass concretecompaction | Vibrators | Theoretic compactionefficiency(m³/h) | Required minimum lifting power of theexcavator(kN) | Required flow at 180bar(l/min) | Total weight(kg) |
VM2HD | 2 | 70-100 | 7.5 | 32 | 660 |
VM3HD | 3 | 105-150 | 8.6 | 48 | 730 |
VM4HD | 4 | 140-200 | 10.3 | 64 | 850 |
* Depending on the concrete characteristics only the pureconcreting time is considered (without moving, respectively newpositioning the excavator.)
** Additionally the hydraulic system of the excavator must haveenough reserve capacity for the necessary movements of theexcavator arm.
