ELGRA 89 Series Percussion Post Driver

See Our Amazing 89 Series In Action!

We can safely say ALL new post drivers sold on the market today require safety screens - UNTIL NOW!
ELGRA has been inspired to produce a new concept of driving posts into the ground. This is the first one of its kind here in Australia.

Here at ELGRA we have designed and manufactured a well-built robust post driver to outperform all other post drivers. Due to its clever design, there is a considerable saving in overhead weight when fully extended, compared to the old free fall hammers. By reducing this overhead weight, it makes the post driver stable and far safer to operate on steeper slopes.

Power Head 89 Post Driver Features

The Power Head cannot be dry fired as the main head requires material (post) under it to allow the head to retract up inside the main body. This then allows the head to start beating at the same time you activate the retract head lever. Once the post is in the ground at your set height, you let the levers spring into the centre. The main Power Head ram has an adjustable valve, this allows you to set different pressures on the head. With the Power Head Series, once you activate the lever you get continuous hits from 450-950bpm. The Power Head Series also comes with hands free hydraulic swing auger into the drill position, it also has hydraulic down force for those tough jobs.

  • 3 point linkage, Excavator or Skid Steer mounts available
  • Adjustable Down Force on Power Head
  • Continuous Hitting Power from Start to Finish
  • Custom size post guides available
  • No Greasing Required
  • Hydraulic Tilt Features:
  • Sideway Tilt: East/West = 18 degrees
  • For/Aft Tilt: North/South = 12 degrees
  • Hydraulic Swing on Auger into Drill Position

Work Cover Compliant!
Post Driver, S89, 75 Cell Driver by El-Gra Engineering, Nowra, NSWAs stated in the WorkCover and WorkSafe 2009 Legislation - All post drivers with a free falling hammer MUST be fitted with a safety screen/guards, the hammer must be fully enclosed 300mm below the lowest point of the hammer stop and 2.4m to the top of the screen from the ground. If the guard is opened the drop speed of the hammer must be restricted to a maximum 100mm/second. If the guard is removed the hammer must remain inoperable.

Being that it's all hydraulically driven (cell included), it gives you the operator, a combination of power, manoeuvrability and versatility. It will save you time, and that will save you money.

And it delivers - with Four Power Head Options:

OPTION 1 50 Cell
