Abstract
An excavator for use on slopes having an incline above 30 degrees, the excavator comprising an undercarriage, a propulsion system and a house rotatably mounted to the undercarriage, wherein a rigid member extends upwardly from the undercarriage, through the house and around which the house rotates, the rigid member supports a cradle to which an engine power pack is mounted within the house, the cradle allowing the engine power pack to tilt within the cradle so that it stays generally horizontal as the excavator travels over a slope.
Claims19
An excavator for use on slopes having an incline above 30 degrees, the excavator comprising:
- an undercarriage;
- a propulsion system;
- a house rotatably mounted to the undercarriage;
- and
- a rotary union or hydraulic swivel,
- wherein a rigid member extends upwardly from the undercarriage, through the house and around which the house rotates, the rigid member supports a cradle to which an engine power pack is mounted within the house, the cradle allowing the engine power pack to tilt within the cradle so that the engine power pack stays generally horizontal as the excavator travels over a slope, and
- wherein the rotary union or hydraulic swivel are coupled to the rigid member and mounted at an upper part of the house, the rotary union or hydraulic swivel being in fluid communication with hydraulic cylinders on the house for operating a working assembly of the excavator and configured for providing continuous slewing of the house.
An excavator for use on slopes having an incline above 30 degrees, the excavator comprising:
- an undercarriage;
- a propulsion system;
- and
- a house rotatably mounted to the undercarriage,
- wherein a rigid member extends upwardly from the undercarriage, through the house and around which the house rotates, the rigid member supports a cradle to which an engine power pack is mounted within the house, the cradle allowing the engine power pack to tilt within the cradle so that the engine power pack stays generally horizontal as the excavator travels over a slope, and
- wherein the rigid member has members extending around the engine power pack to ends thereof for rotational engagement with corresponding members formed on the cradle.
