Apparatus for lifting and moving an upright cylindrical container

Abstract

A work load lifting and moving apparatus is formed by a wheel supported horizontal main frame in turn supporting a mast assembly having a vertically reciprocal lifting frame gripping and lifting the work load by a hoist supported by the mast assembly. Other lifting apparatus supported by the main frame tilts the vertical axis of the work load in a forward direction.

1 . A lifting, moving and tilting apparatus for a cylindrical work load, comprising: 
 base frame means having a forward work load straddling end and a rearward steering end;    wheel means journaled by and depending from said base frame means for movement from one location to another;    mast means including an L-shaped mast having a foot portion pivotally mounted on said base frame means and having a leg portion projecting vertically upward from the central portion of said base frame for vertical forward tilting movement about a horizontal axis;    screw jack means mounted on the rearward end portion of said base frame means and connected with the depending end portion of said mast assembly for forward tilting of said mast assembly;    lifting frame means having vertically spaced work load engaging arms vertically slidable on said mast leg;    work load band clamp means mounted on said lifting frame means for impinging the work load against said arms; and,    hoist means mounted on the mast assembly and connected with the lifting frame means for raising and lowering a work load.    
     
     
         2 . The apparatus according to  claim 1  in which pairs of lifting frame arms straddle opposite sides of said mast and further include: 
 bearing means transversely supported by said arms for frictional contact with forward and rearward surfaces of said mast; and,  
 a part circular work load contacting member extending between and connected with the respective said pairs of arms forwardly of said mast.  
 
     
     
         3 . The apparatus according to  claim 2  and further including: 
 work load supporting lips on the lower most part circular member.  
 
     
     
         4 . The apparatus according to  claim 2  in which the wheel means includes: 
 a pair of caster wheels under the rearward end portion of said base frame means; and,  
 a pair of auxiliary wheels operatively supported by said base frame means rearward end portion and normally out of contact with a supporting surface for supporting the apparatus in two wheel dolly fashion when the vertical axis of the mast is tilted rearwardly.
