Latest Patents

One of Sawitzki's latest patents is for a vane motor. This innovative design features a rotor body driven by compressed air, equipped with vane gaps for radially movable vanes. The rotor shaft is designed to rotatably bear the rotor body relative to a motor bushing. Additionally, the patent includes a method for lubricating the vane motor, ensuring long-lasting and low-service operation. The rotor shaft is configured as a hollow shaft with a lubricant reservoir that is accessible from the outside, enhancing the motor's efficiency.

Another significant patent by Sawitzki is a fall protection device for a hoist. This invention includes a hoist body with a drive mechanism for raising or lowering a hoist chain or cable. The hoist is suspended from a support device, and a safety device with a coupling element and damping element is mounted between the hoist body and the support device. This design allows the hoist body to drop a certain height before the coupling element becomes taut, effectively damping the fall under load.
