  • the present invention relates to a semi-underground waste container comprising a remote controlled opening and closing system of a lifting bag, a remote controlled opening and closing system kit of a lifting bag for retrofitting a semi-underground waste container and a method for remotely opening and closing a lifting bag of a semi-underground waste container.
  • a semi-underground waste container is based on a vertical structure in which generally over 50 % of the container is located underground.
  • the containers occupy a minimal surface area that allows practical waste collection solutions even in small and confined spaces.
  • Semi-underground waste containers enable the use of larger containers. Furthermore, gravity compacts the waste by its own weight inside the containers. Therefore, semi-underground waste containers enable less frequent waste collection.
  • the large waste capacity reduces emptying traffic in the area and minimizes environmental load. Increasing intervals between emptyings reduces fuel costs and emissions.
  • Embodiments of the invention provides remote controlling means for opening and closing the lower part of the lifting bag and a method for remotely opening and closing a lifting bag of a semi-underground waste container for emptying.
  • a remote controlled opening and closing system of a lifting bag of a semi-underground waste container for closing and opening the lifting bag.

  • the remote controller is wirelessly connected to the wince and arranged to transmit control signals to the wince for closing and opening the lifting bag as a result of selection of a switch.
  • a first end of the pulling line is connected to the lower part of the lifting bag and the second end to the drum of the wince. If the selection switch for closing the lifting bag is selected, the emptying device receives the closing control signal and the pulling line is pulled by the wince so that the pulling line wraps around the drum and the lifting bag closes. And if the selection switch for opening the lifting bag is selected the wince receives the opening control signal and the pulling line is released by the wince so that the pulling line un-wraps from the drum and the lower part of the lifting bag opens.
  • the lifting bag is a soft lifting bag and the first end of the pulling line is connected around the lower part of the lifting bag, and for closing the lifting bag, the pulling line is pulled so that first end of the pulling line compresses around the lower part of the lifting bag, and for emptying the lifting bag, the pulling line is released so that the compression of the first end of the pulling line around the lower part of the lifting bag releases.
  • the lower part of the lifting bag is a container and the first end of the pulling line is connected to the container, and for closing the lifting bag, the pulling line is pulled so that the container tilts underneath the upper part of the lifting bag, and for emptying the lifting bag, the pulling line is released so that the container tilts away underneath the lifting bag.
  • the pulling line is a polypropylene rope.
  • the pulling line tube is a flexible hydraulic hose.
