Abstract
Extended-reach lift apparatus for remote accessing of low-clearance areas is provided. The apparatus includes a vehicle whose frame supports a vertically pivotable telescoping boom which is elevatable by means of hydraulic rams. An extended tilt head is provided on the free end of the boom which includes parallel upper and lower link members of equal length. A work implement support having a discrete work implement tilting cylinder is attached to the remote ends of the upper and lower links of the tilt head. A hydraulic cylinder extending between the boom and the lower link of the tilt head provides separate tiltability of the tilt head while the design of the tilt head mechanically assures the maintenance of the attitude of the work implement without requiring additional hydraulic compensation during such tilting.
