Claims19
A materials handling vehicle comprising:
- a vehicle power unit having a longitudinal centerline;
- a monomast coupled to said vehicle power unit and having a centerline offset from and generally parallel with said longitudinal centerline of said vehicle power unit, said monomost comprising:
- a first stage weldment coupled to said vehicle power unit;
- a second stage weldment positioned to telescope over said first stage weldment;
- a third stage weldment positioned to telescope over and surround, when retracted, said first and second stage weldments;
- and
- a mast weldment lift structure for effecting lifting movement of said second and third stage weldments relative to said first stage weldment;
- a fork carriage apparatus movably coupled to said monomast, said fork carriage apparatus being movably coupled to said third stage weldment;
- and
- fork carriage apparatus lift structure for effecting lifting movement of said fork carriage apparatus relative to said third stage weldment and being located outside of said third stage weldment, at least a substantial portion of said fork carriage apparatus lift structure falling within a blocked viewing area for an operator so as not to block any additional operator viewing area.
