Vibratory hammers are so compact and lightweight—compared to their high-impact pile driving counterparts—they can easily be attached to your excavator.
This provides you with the capability of driving piles, sheeting, and caissons in what might be otherwise hard-to-reach areas. Vibratory hammers are also quieter and safer to use near other existing foundations since the oscillation of the vibration going from the hammer through the pile and into the ground can be better contained to a specified area.
Vibratory hammers are also less expensive to purchase or rent, and they don’t require the need for a crane or extensive rigging, which is also better for your bottom line.
They can be driven by electricity or hydraulics, and can easily plug the right unit into the hydraulic system of your excavator when using that as the pile-driving vehicle.
Other advantages of an excavator-mounted vibratory hammer include:
-Hydraulic Clamp -The clamp attached to the hydraulic mount on your excavator allows your equipment operator to easily hold a pile in place while being driven.
This reduces the need for additional equipment that might normally be needed to bring the piles to the spots where they will be driven and hold them in place because the excavator can simply pick them up and drive each into their predesignated spots.
-Gear Box - The gearbox on most vibratory hammers allows the clamp to rotate 360 degrees. This might not be a big deal if you are simply driving piles or pipes, but when trying to place sheeting piles or caissons, positioning is very important.
The rotation gearbox provides you with the ability to leave the excavator in place while rotating the pile, so piles that are being placed near existing structures or into the water from a shoreline location can easily be manipulated.
- Vibration Suppression - Vibratory hammers operated by sending high-frequency vibrations from the apparatus through the pile and into the ground.
Since the vibrations can go in both upward and downward, vibration suppressors help to keep the vibration from traveling back up into the arm of the excavator while channeling them back down through the pile.
This provides a very fast and effective way to drive materials into the soil.
If you do not already have a vibratory hammer but need to drive piles for a specific foundation project, you may want to consider working with a heavy machinery rental company that can supply you with a number of different options. Renting is a great option if you:
- Only need the equipment for a short amount of time.
- Don’t want to tackle the expense of purchasing a unit.
- Don’t want to have the extra expenses associated with storing and maintaining the equipment.
- Potentially need a variety of different types of vibratory hammers.
- Want expert advice on what types of hoses and mounts you need to work with your existing excavator.
- Also need to rent an excavator and or machine operator.
Conclusion
Vibratory hammers are a great way to drive different kinds of piles, pipes, sheeting, and caissons into a variety of soil conditions. You may want to consider renting a vibratory hammer that is compatible with your excavator if you want expert advice on what kind of hoses and mounts you’ll need for your vehicle, and you don’t want the added expense of purchasing, storing, and maintaining the vibratory hammer yourself.
