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.
Claims
exact text as granted — not AI-modifiedI 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 boom assembly secured to the frame assembly at a first end and to a screed head at a second end, the 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; a drive assembly secured to support and move the frame assembly; a boom assembly secured to the frame assembly at a first end and to a screed head at a second end, the 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.Join the waitlist — get patent alerts
