Latest Patents

One of Endres' latest patents is a flameless heater for an operator's cab. This innovative device features automatic heat control, utilizing a hydraulic pump to provide pressurized fluid. The fluid flows through a restrictive orifice, generating thermal energy and raising the fluid temperature due to a drop in hydraulic pressure. The heated fluid then circulates through a heat exchanger, where a fan blows air over it to deliver hot air into the operator's cab. A spool valve, connected in parallel with the orifice, helps to limit the rise in fluid temperature, while a temperature sensor selectively opens and closes the spool valve to maintain the fluid temperature within specified limits.

Another notable patent is the hydraulic crane aerial platform attachment. This attachment is designed for cranes and includes an extensible boom with a basket that is pivotally suspended from the boom tip. A loop on the bucket engages a projection secured to the boom when the bucket is pivoted adjacent to the boom, allowing the boom to be fully retracted. A hand lever-operated brake locks the bucket relative to the boom when in a working position, enhancing safety and functionality.
