Patent ID: 7445053

Claim:
A ripping device comprising: a vehicle body of an earthmoving vehicle; a beam; a shank mounted on the beam; an arm including a first attachment end pivotally coupled to the vehicle body about a first pivot axis, and a second attachment end pivotally coupled to the beam about a second pivot axis; a single hydraulic tilt cylinder disposed only on a first side with respect to a longitudinal vertical center plane of the ripping device and spaced apart from the longitudinal vertical center plane, the hydraulic tilt cylinder including a first tilt cylinder end pivotally coupled to the vehicle body about a third pivot axis and a second tilt cylinder end pivotally coupled to the beam about a fourth pivot axis; and a single hydraulic lift cylinder disposed only on a second side with respect to the longitudinal vertical center plane of the ripping device and spaced apart from the longitudinal vertical center plane, the hydraulic lift cylinder including a first lift cylinder end configured to be pivotally coupled to the vehicle body about a fifth pivot axis and a second lift cylinder end pivotally coupled to the beam about a sixth pivot axis; the fifth pivot axis of the first lift cylinder end of the hydraulic lift cylinder being located upward of the third pivot axis of the first tilt cylinder end of the hydraulic tilt cylinder, and the sixth pivot axis of the second lift cylinder end of the hydraulic lift cylinder being located downward of the fourth pivot axis of the second tilt cylinder end of the hydraulic tilt cylinder.
