A scissors lift vehicle comprising: a chassis comprising a pair of parallelly oriented channels, each channel comprising a first forward end and a second aft end, said first forward ends of each of said channels coupled together using a forward plate extending orthogonally between said first forward ends, said second aft ends of each of said channels coupled together using an aft plate extending orthogonally between said second aft ends and parallel to said forward plate; a first pair of wheels disposed at one end of said chassis and a second pair of steering wheels disposed at an opposite end of said chassis, the wheels (104, 312, 316) configured to roll along a travel surface and comprising a circular profile having a radius R, each wheel (104,312,316) of each pair of wheels spaced apart laterally with respect to the other wheel of the pair, the pairs of wheels spaced apart longitudinally from the other pair of wheels; a pair of tracks, each of the pair of tracks comprising an upper surface, a lower surface and a thickness extending therebetween, said pair of tracks extending aft at a height less than R above the travel surface from said forward plate parallel to said pair of channels; a pivot connection coupled to said aft plate at a height less than R above the travel surface; and a scissors stack assembly comprising a plurality of paired scissors linkages extendable from a retracted position to an extended position, each scissors linkage of a first pair of scissors linkages (120, 122) of the plurality of paired scissors linkages, pivotally coupled to a respective pivot connection, each scissors linkage (340, 342) of a second pair of scissors linkages (124, 126) of the plurality of paired scissors linkages comprising a respective truck coupled to a distal end of each scissors linkage (340, 342) of said second pair of scissors linkages (124, 126), wherein each respective truck is configured to roll on said upper surface of a respective track and comprises: an inner support plate, an outer support plate, and a roller assembly extending therebetween; a linkage connection configured to couple to said distal end of a respective scissors linkage of said second pair of scissors linkages (124, 126); and a track keeper comprising a body extending from at least one of said inner support plate and said outer support plate to face-to-face proximity to said lower surface. a chassis comprising a pair of parallelly oriented channels, each channel comprising a first forward end and a second aft end, said first forward ends of each of said channels coupled together using a forward plate extending orthogonally between said first forward ends, said second aft ends of each of said channels coupled together using an aft plate extending orthogonally between said second aft ends and parallel to said forward plate; a first pair of wheels disposed at one end of said chassis and a second pair of steering wheels disposed at an opposite end of said chassis, the wheels (104, 312, 316) configured to roll along a travel surface and comprising a circular profile having a radius R, each wheel (104,312,316) of each pair of wheels spaced apart laterally with respect to the other wheel of the pair, the pairs of wheels spaced apart longitudinally from the other pair of wheels; a pair of tracks, each of the pair of tracks comprising an upper surface, a lower surface and a thickness extending therebetween, said pair of tracks extending aft at a height less than R above the travel surface from said forward plate parallel to said pair of channels; a pivot connection coupled to said aft plate at a height less than R above the travel surface; and an inner support plate, an outer support plate, and a roller assembly extending therebetween; a linkage connection configured to couple to said distal end of a respective scissors linkage of said second pair of scissors linkages (124, 126); and a track keeper comprising a body extending from at least one of said inner support plate and said outer support plate to face-to-face proximity to said lower surface.
