Abstract:
A lift assembly for lifting and tilting an implement relative to a frame of a work machine, comprising:a lift arm having a frame pin bore, a cylinder pin bore, an implement pin bore, and a linkage pin bore, wherein (i) said frame pin bore and said cylinder pin bore define a first line, (ii) said frame pin bore and said implement pin bore define a second line, (iii) said second line is located above said first line, (iv) said first line and said second line define an angle which is greater than three degrees, (v) a plane intersects said first line at a center point of said cylinder pin bore and is normal to said first line, (vi) said plane divides said lift arm into a frame-side segment and an implement-side segment, (vii) said frame side segment includes a first extension and a second extension spaced apart from each other so as to define a lever space therebetween, and (ix) said first line includes a first segment which is entirely coincident with said implement-side segment of said lift arm, (viii) said linkage pin bore is defined in said frame-side segment;a tilt lever pivotably coupled to said lift arm at said linkage pin bore such that said tilt lever extends through said lever space;a tilt cylinder, coupled to said tilt lever, for tilting said implement which is pivotably coupled to said lift arm; anda lift cylinder for moving said lift arm between an upper position and a lower position, wherein said lift cylinder is coupled to said lift arm at said cylinder pin bore.
