         7 . The apparatus of  claim 1 , wherein the actuator includes two pistons, each piston has a first end connected to the frame, and a second end connected to the wrap support. 
     
     
         8 . The apparatus of  claim 1 , wherein the adjustable wrap holder further comprises a guide disposed between the wrap support and the frame. 
     
     
         9 . The apparatus of  claim 8 , wherein the guide comprises a scissor lift. 
     
     
         10 . The apparatus of  claim 8 , wherein the adjustable wrap holder further comprises a cover over the actuator. 
     
     
         11 . The apparatus of  claim 1 , further comprising:
 a step ladder assembly attached to the frame.   
     
     
         12 . The apparatus of  claim 11 , wherein the step ladder assembly comprises:
 a first step board having a proximal end connected to the frame by a hinge and a distal end for latching to a support member, and the support member is attached to the frame.   
     
     
         13 . The apparatus of  claim 12 , wherein the first step board includes two or more pieces arranged in telescope. 
     
     
         14 . The apparatus of  claim 12 , wherein the step ladder assembly further comprises:
 a second step board pivotably attached to the frame, wherein the second step board is shorter than the first step board.   
     
     
         15 . The apparatus of  claim 14 , wherein the step ladder assembly further comprises:
 a link connected between the first step board and the second step board.   
     
     
         16 . The apparatus of  claim 1 , further comprising:
 one or more guide arms attached to the frame, wherein the guide arms are positioned to align with openings of standard pallet blocks.   
     
     
         17 . The apparatus of  claim 1 , further comprising:
 wheels attached to the frame.   
     
     
         18 . The apparatus of  claim 17 , further comprising:
 a handle for steering.   
     
     
         19 . A foldable wrap holder, comprising:
 a first support bar;   a second support bar;   a third support bar;   a first flexible belt connecting the first and second support bars; and   a second flexible belt connecting the second and third support bars.   
     
     
         20 . The foldable wrap holder of  claim 19 , wherein each of the first, second, and third support bar includes a hanging peg.
