Tiltable work platform

Abstract

A work platform assembly 10 of the invention has a base 12 and a work platform 36 movable with respect to the base 12 . The work platform 36 can be connected to the base 12 by at least one pivot arm. A lift device 64 is configured to move, e.g., raise and tilt, the work platform 36 with respect to the base 12 . In one particular embodiment, the work platform 36 is connected to the base 12 by a plurality of pivot arms that are pivotally connected to the base 12 and the work platform 36 . In one embodiment, the lift device 64 is a pneumatic lift bag located between the base 12 and the work platform 36 .

1 . A work platform assembly, comprising: 
 a base;    a work platform movable with respect to the base, wherein the platform is connected to the base by at least one pivotable support; and    at least one lift device configured to both lift and tilt the platform with respect to the base.    
   
   
       2 . The work platform assembly of  claim 1 , wherein the work platform is connected to the base by at least one forward support and at least one rear support.  
   
   
       3 . The work platform assembly of  claim 2 , wherein the forward supports are connected at or near the front of the work platform.  
   
   
       4 . The work platform assembly of  claim 3 , wherein the rear supports are connected to the work platform rearwardly of the front supports.  
   
   
       5 . The work platform assembly of  claim 1 , wherein the lift device includes at least one pneumatic lifting bag.  
   
   
       6 . The work platform assembly of  claim 1 , including a turntable connected to the base.  
   
   
       7 . The work platform assembly of  claim 2 , including a receiver operably connected to the at least one rear support and configured to engage the lift device.  
   
   
       8 . A work platform assembly, comprising: 
 a base;    a work platform movable with respect to the base;    a first forward support spaced from a second forward support, with one end of each forward support pivotally connected to the base and the other end of each forward support pivotally connected near the front of the work platform;    a first rear support spaced from a second rear support, with one end of each rear support pivotally connected to the base and the other end of each rear support pivotally connected to the work platform rearwardly of the front supports; and    a pneumatic lifting device configured to lift and tilt the work platform with respect to the base.    
   
   
       9 . The work platform assembly of  claim 8 , including a receiver operably connected to the rear supports and configured to engage the lifting device.  
   
   
       10 . The work platform assembly of  claim 8 , including a turntable connected to the base.  
   
   
       11 . The work platform assembly of  claim 8 , including a stop connected to the work platform.  
   
   
       12 . The work platform assembly of  claim 8 , wherein the lifting device is a pneumatic lift bag.  
   
   
       13 . The work platform assembly of  claim 12 , wherein the lift bag is a wedge-shaped lift bag.  
   
   
       14 . A work platform assembly, comprising: 
 a base;    a work platform connected to the base by a pair of first supports spaced from a pair of second supports, with one end of the first and second supports pivotally connected to the base and the other end of the first and second supports pivotally connected to the work platform; and    a pneumatic lift bag positioned between the base and the work platform such that inflation of the lift bag raises and tilts the work platform with respect to the base.
