Abstract
An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a front end and rear ends and a pair of spaced vertically oriented stabilization legs supporting a generally horizontal front member. An extendable boom assembly is provided having front and rear ends, and an exterior boom section pivotably secured to the frame assembly proximate said rear end. The extendable boom assembly is also adjustably mounted on said front member to allow generally lateral motion of the boom.
Claims17
An apparatus for screeding concrete to produce a level finished surface comprising:
- a frame assembly having a front end and rear ends, said frame assembly having a pair of spaced vertically oriented stabilization legs secured to the front end thereof, said spaced legs supporting a generally horizontal front member therebetween, and at least one stabilization leg secured to the rear end thereof;
- an extendable boom assembly having front and rear ends, and an exterior boom section secured to said frame assembly proximate said rear end thereof and to a screed head at said front end, said extendable boom assembly adjustably mounted on said front member;
- and
- an actuator secured between said front member and said extendable boom assembly to impart generally lateral motion thereto.
An apparatus for screeding concrete to produce a level finished surface comprising:
- a frame assembly having a front end and rear end, said frame assembly having a pair of spaced vertically oriented stabilization legs secured to the front end thereof, said spaced legs supporting a generally horizontal arcuate front member therebetween, and at least one stabilization leg secured to the rear end thereof, each of said stabilization legs having a leveling actuator secured thereto for adjusting an elevation of said frame assembly and thereby said screed head;
- an extendable boom assembly having front and rear ends, said front end adjustably secured to said front member;
- an actuator with an extendable arm thereon, said actuator secured at a first end to said front member;
- and secured at a second end to said extendable boom assembly to impart generally lateral motion to said boom.
