APE has received a patent on its variable fuel delivery pump that fits all APE, Delmag, ICE, and Pileco diesel hammers. The APE design allows the operator to see the exact fuel setting by observing the same indicator pin that is on the standard four position pump. Pileco, ICE, and Berminghammer rely on a pressure gauge, which changes due to hydraulic line length and oil temperature. The best way to know what fuel setting your on is to be able to read the actual fuel setting and this is what APE’s patented system does. This new technology prevents the possibility of over stroking the hammer due to improperly knowing where the fuel setting are.
APE/J&M has recently delivered 5 J&M Model 115 HIH’s to a Cleveland jobsite that is an old garbage landfill that has been capped and a new shopping mall is being constructed on it. Closed end pipe piles are being driven thru the trash to support the buildings.
One interesting feature of the piles on this job is that although 10.75″ pipe piles are being driven, a 16″ shoe is welded on the end of the pile, eliminating all wall friction and making the pile a true end bearing pile. This was designed in such a way because of a fear that splicing piles could ignite the methane gas that is released as the pile is being driven thru the decaying garbage in the ground. The oversize shoe creates a large void between the wall of the pile and the soil and allows the methane to escape.
