Side-step concrete screeding apparatus

Abstract

An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a pair of spaced vertically oriented stabilization legs secured to the front end thereof supporting a generally horizontal front member. An extendable boom assembly is secured to the frame assembly at a first end and to a screed head at a second end. A side-step assembly includes an actuator with an extendable arm secured to the boom assembly to impart generally lateral motion.

I claim: 
     
         1 . An apparatus for screeding concrete to produce a level finished surface comprising:
 a frame assembly having a front end and rear end, the frame assembly supporting a generally horizontal front member therebetween;   a drive assembly rotatably secured to support the frame assembly;   an extendable boom assembly secured to the frame assembly at a first end and to a screed head at a second end, the extendable boom assembly adjustably disposed on the front member; and   a side-step assembly having an actuator with an extendable arm thereon, the actuator secured at a point to the front member, and the extendable arm secured to the boom assembly to impart generally lateral motion thereto.   
     
     
         2 . An apparatus as claimed in  claim 1  wherein the actuator is an hydraulic actuator. 
     
     
         3 . An apparatus as claimed in  claim 1  wherein the actuator is a linear actuator. 
     
     
         4 . An apparatus as claimed in  claim 1  comprising:
 a pair of spaced vertically oriented stabilization legs secured to the front end of the frame, the spaced legs supporting a generally horizontal front member therebetween. 
 
     
     
         5 . An apparatus as claimed in  claim 4  comprising:
 a vertically oriented stabilization leg secured to the frame assembly at the rear end thereof, whereby the stabilization legs level the frame and the screed head. 
 
     
     
         6 . An apparatus for screeding concrete to produce a level finished surface comprising:
 a frame assembly having a front end and rear end, the frame assembly supporting a generally horizontal front member therebetween;   an extendable boom assembly secured to the frame assembly at a first end and to a screed head at a second end, the extendable boom assembly adjustably disposed on the front member; and   a side-step assembly having an actuator with an extendable arm thereon, the actuator secured at a point to the front member, and the extendable arm secured to the boom assembly to impart generally lateral motion thereto.   
     
     
         7 . An apparatus as claimed in  claim 1  wherein the actuator is an hydraulic actuator. 
     
     
         8 . An apparatus as claimed in  claim 1  wherein the actuator is a linear actuator. 
     
     
         9 . An apparatus as claimed in  claim 1  comprising:
 a pair of spaced vertically oriented stabilization legs secured to the front end of the frame, the spaced legs supporting a generally horizontal front member therebetween; and 
 a vertically oriented stabilization leg secured to the frame assembly at the rear end thereof, whereby the stabilization legs level the frame and the screed head.
