The APE Model 250 Variable Moment Hammer was called to duty. Malcolm Drilling was in need of removing a couple of 24″ pipe pile filled with concrete. With APE custom built jaws that simply bolted into a APE 25″ wood clamp, then installed under the APE 250VM, Malcolm was able to make short work of this task with minimum radial vibration.
The superintendent “Chad” noticed one of the benefits of the variable moment feature. There was absolutely no crane boom vibration when the pile was removed and the hammer was phased out. That said, using a hydraulic squirt boom crane will no longer be taboo when using vibratory hammers. Allowing for quick and easy crane set ups saving time and money.
