First Claim
Patent Images
1. A mobile lift comprising:
- a generally rectangular, horizontal frame structure including (i) first and second laterally spaced telescoping side frame members, and (ii) front and back telescoping cross-frame members operatively connected between the side frame members for adjustability of the frame structure in length from front to back and in width from side to side;
front and back pairs of vertical telescoping frame members supporting the horizontal frame structure proximate the front and back corners respectively for adjustability of the height of the horizontal frame structure;
article lift apparatus connected in fixed relation to one of said frame structure and said vertical frame members, and adapted to engage a load for raising and lowering a load from the ground;
a pair of laterally spaced telescoping horizontal frame members connecting the front and back vertical frame members on each side of the frame structure for adjustability between said front and back pairs associated with adjustability the side frame members of said frame structure;
front and back rolling supports proximate the front and back corners of the lift and supporting the frame members and frame structure for ground mobility;
one of a speed reduction system and a braking system connected to said rolling supports; and
a steering mechanism for at least one of said front rolling supports and said back rolling supports.
