APPARATUS AND METHOD FOR IMPROVING THE CONTROL OF A CONCRETE SCREEDING MACHINE
First Claim
1. A screeding machine for screeding a concrete surface having a partially cured concrete area and a newly placed concrete area, said screeding machine comprising:
- a wheeled unit having a plurality of wheels for moving said wheeled unit over a support surface;
a screeding head assembly having a grade setting device and a vibrating member, wherein said screeding head assembly is movable over the concrete area via an extendable and retractable boom assembly extending from said wheeled unit;
wherein said screeding machine comprises at least one of;
(a) a boom speed cruise control for automatically controlling the travel speed of said screed head assembly during a screeding pass so that the travel speed of a first screeding pass of said screed head assembly is substantially the same as the travel speed of at least one subsequent screeding pass of said screed head assembly;
(b) an auto-stabilizer control that automatically adjusts the stabilizer actuators of said wheeled unit of said screeding machine to a preselected degree of extension in response to a user input;
(c) a control for automatically controlling the lowering of said screed head assembly toward and to the concrete surface and automatically activating said grade setting device and said vibrator at a beginning of a screeding pass and automatically deactivating said grade setting device and said vibrator in response to said screed head assembly being raised away from the concrete surface at the end of the screeding pass; and
(d) an auto-screed control that allows the operator to select a maximum value for at least one of a boom extension speed, a boom retraction speed, a boom rotation speed and a screed head rotation speed, whereby a respective speed of at least one of these functions of said screeding machine is limited to the selected value in response to the operator selecting an auto-screed mode.

Abstract
A screeding machine including at least one of (a) a boom speed cruise control for automatically controlling the travel speed of the screed head assembly, (b) an auto-stabilizer control that automatically adjusts the stabilizer actuators of the screeding machine to a preselected degree of extension, (c) a control for automatically controlling the lowering of the screed head assembly toward and to the concrete surface and automatically activating the auger and vibrator at a beginning of each screeding pass and automatically deactivating the auger and vibrator in response to the screed head assembly being raised away from the concrete surface at the end of a screed pass, and (d) an auto-screed mode that allows the operator to select maximum values for at least one of a boom extension speed, a boom retraction speed, a boom rotation speed and a screed head rotation speed.

11. A screeding machine for screeding a concrete surface having a partially cured concrete area and a newly placed concrete area, said screeding machine comprising:
-
a wheeled unit having a plurality of wheels for moving said wheeled unit over a support surface; a screeding head assembly having a grade setting device and a vibrating member, wherein said screeding head assembly is movable over the concrete area via an extendable and retractable boom assembly extending from said wheeled unit; and a joy-stick steering system that is operable to control the steering of at least two of said wheels, said joy-stick steering system providing an operator steering control of said at least two wheels by means of a joy-stick control handle, wherein the steering of said wheels of said screeding machine is controlled electronically by operator positional input at said joy-stick control handle. - View Dependent Claims (12)

13. A screeding machine for screeding a concrete surface having a partially cured concrete area and a newly placed concrete area, said screeding machine comprising:
-
a wheeled unit supporting a screeding head assembly having a grade setting device and a vibrating member, wherein said screeding head assembly is movable over the concrete area via an extendable and retractable boom assembly; a right joystick control and a left joystick control for controlling respective functions of said screeding machine, wherein said right joystick control at least initially controls first functions and said left joystick control controls second functions; and a joystick swap control that is actuatable by an operator of said screeding machine, whereby said right joystick control controls said second functions and said left joystick control controls said first functions in response to actuation of said joystick swap control. - View Dependent Claims (14)
