Abstract
Provided in this disclosure is a digger/derrick system (or generally any type of machine) having a diesel engine to power a hydraulic system for raising and lowering the digger/derrick and powering other components. The system includes a centrifugal clutch that engages the diesel engine while the engine is running, thereby powering an electrical generator that drives the hydraulic pump while also charging an on-board battery bank system. When the engine is turned off, the centrifugal clutch is decoupled. The battery banks then power the generator, which in turn drives the hydraulic pump. In this manner, the digger/derrick offers the advantages of noise reduction as the hydraulic systems can be operated without running a noisy diesel engine. This noise reduction after enhances safety since operators elevated in the derrick and operators on the ground can more readily communicate to give clear warnings to avoid danger and other undesirable circumstances.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
