Dozens of APE 200 Vibratory Pile Driver/Extractors Rushed to UAE

MASSIVE FAILURES OF OUR COMPETITION’S MACHINES PROMPTS APE BUILD UP IN UAE

APE Austria has begun a massive shipment of new APE Model 200 vibratory pile driver/extractors to the UAE. This is in response to recent electronic and overheating of our competition’s so-called new units in hot weather conditions. APE machines are will known for their simplicity and ability to handle both the hot Saudi Arabian sun and the cold of Alaska. The secret is our unique kidney loop cooling circuit which can be reversed in cold weather.

APE units come with massive heat exchangers and a special kidney loop oil cooling system that keeps the machine running even in 125 degree temperatures. APE developed a simple electrical system to mate with the advanced Tier III CAT engines. We avoided adding fancy touch screen panels that are subject to code failures that shut the unit down and require re-programming to get started again. APE machines are simple yet advanced. Our hydraulic gauges are old school simple yet our CAT Electronics are fuel efficient.

Our power units feature a built-in spare hydraulic tank, CAT Tier III engine, Super Heavy Duty radiator and oil cooler, kidney loop oil system, all stainless steel control panels, tachometer in the remote pendant (found only on APE machines) tool box with spare jaws and hoses and tools to do all the maintenance work and a 5 year warranty.

The APE 200 has the world’s greatest lifting capacity, heavy metal eccentrics, helical gears, one piece gear/eccentric, giant spherical double roller bearings, patented two stage suppressor, 0-ring seals on all parts for ready operation under water, clamps with nylotron lined slides and one piece cylinders and larger jaws for excellent gripping ability.

The APE 200 is the world’s most demanded vibratory pile driver due to its many patented features.

False and Misleading Vibro Specifications-Watch Out for Tricks

Are you purposely being mislead?

One of the first steps in selecting the right size vibratory pile driver is to do an amplitude equation to determine whether the vibro has enough amplitude to shake the pile. To do this calculation one must know the eccentric moment of the machine. Some manufacturers fail to list the eccentric moment of their machine. Why would this important information be missing from their specifications? The answer: To make you believe their hammer is really bigger than it is. A good example is HMC’s spec sheet on the Movax Sonic Side Grip. (see their literature included in this blog.) It is missing the eccentric moment information.

What is the dynamic energy of this hammer? 100 tons they say. That would require over 800 inch pounds of eccentric moment! Not possible! What is the inch pounds or eccentric moment? Without this info there is no way to do a simple amplitude equation or know the true force in tons. I guess you have to risk that once it gets to the job it will drive the piles. Come on HMC, put your eccentric moment on the spec sheet please. Why hide it?
