Abstract
A single-acting, three-stage, four-section telescopic ram for use in conjunction with a triple-lift type mast in a lift truck. The ram features an extremely low overall length when fully contracted, thus affording good operator visibility. The ram also is capable of producing surprisingly 'high-lift' despite its low contracted profile. Further, the ram features an internal construction that produces constant lifting and lowering speeds for a load, as well as providing for positive control over the sequence of movements of parts in and on an associated mast.
