UMC4000 - Universal blade control

Description

Our UMC4000 blade control system is used on construction and land-leveling machinery or machinery blade attachments to automatically control the blade in earthmoving and grading applications. It could also be used on drainage, trenching or milling machinery. By the use of machine laser receivers, ultrasonic transducers or slope sensors a reference elevation will automatically be transferred to the cutting edge of the blade. The system is ready for integration of GNSS or TPS system using a digital terrain model as reference.

UMC4000 consists of a control unit and a control panel (MMI = man-machine-interface) with joystick and programmable functionality. The system controls up to 8 different hydraulic functions, no matter if tied to On/Off solenoid or proportional valves (PC or PV). Thus, UMC4000 features blade elevation control of up to three height cylinders (main, if there is, plus right and left) and automatic adjustment of both hydraulic side doors of the grading blade. In addition, our MMI steers other functionality such as control of three-point-hitch, hydraulic masts or folding the blade for road transportation, as an example. The UMC4000 is versatility at its best.

Option: MC Assistant

New: For our UMC4000 control series we offer the MC Assistant. This is a software assistant that makes the manual operation of the grading blade easy. If you move the joystick up or down, the blade raises or lowers. If the joystick is back in the centre again, the MC assistant brings the blade automatically into its levelled position. A correction by hand to get the zero-position of the blade is not needed any more. Moreover, the MCA is more precise and faster than hand correction by use of an mechanical scale.

The prerequisite for using this technology are linear hydraulic cylinders, whose stroke position is measured with millimeter precision by an integrated sensor. The corresponding analog or digital height signal is continuously read by our UMC4000 control box and included as an additional control parameter. Cylinder travel limitation and/or centering are thus easily implemented. The stroke of the two height cylinders and, consequently, the cutting edge height of the blade can be defined with the joystick and proportionally controlled manually – first gently and then steadily faster.

Through collaborative development and cooperation, the MC Assistant has been integrated into Rex Leveller graders, tested, and delivered several times. Customers who use the MC Assistant and Rex Leveller levelers are amazed at how easy, fast, and precise manual control can be.

The ideal partner for the MC Assistant is a linear hydraulic mast, which functions like an electrically operated mast, but is significantly more robust and less prone to failure. The leveler is thus fully automatic: Laser receivers can be inserted and removed at the push of a button. The laser level is automatically found. The layer thickness of the material to be paved can be defined with millimeter precision.

Option: 3D Control

In addition to traditional laser, ultrasonic, and inclinometer sensors, our UMC 4000 can also integrate 3D systems from the three leading manufacturers. It doesn't matter whether a GNSS system with one or two GNSS antennas or an automatic total station with prism tracking is integrated. It's important that, in addition to the GPS antenna/prism and the communication modules, the 3D computer is also integrated. This is because it loads the digital terrain model (DTM as a target) and continuously calculates the deviations of the actual measurements from the DTM. The 3D computer transmits the delta, or elevation difference, to our UMC4000 in real time, which then controls the valves of the blade elevation cylinders.

UMC4000 mit 3D Rechnern — UMC4000 mit 3D Rechner

Manual control of the various hydraulic functions with the joystick remains the same as usual; of course, the automatic blade height control can also be activated at the push of a button.
As you are already used to with our 2D sensors, with 3D you can also decide for yourself which 3D system (GNSS or ATS) and which manufacturer, its 3D software, and 3D support seem most suitable for your work. With the UMC4000 system, hardware-wise, only the cable set usually needs to be added or adapted. Otherwise, you can purchase an activation code for the 3D application. Contact us if you are planning to purchase a new UMC4000 with a 3D option or would like to upgrade an existing UMC4000 with a 3D option.
Of course, the handling of the UMC4000 and the plug-and-play sensor system remain the same. When started, the UMC4000 queries which sensors or 3D systems are connected, recognizes them, and then just start your job.

Sensors for UMC4000

Linear laser receiver

Our ULS250 is a 360° laser receiver developed and manufactured for mobile machine grading application.It is fully linear (proportional) over its 25 cm reception height. That means that within its reception window the on-grade position can be moved electronically from the centre to any off-grade position simply by a push on a button.

Product data

5 channel laser receiver

Our SLS220 is a budget-priced 360° laser receiver developed and manufactured for machine control applications. The reception height is 22 cm in total. It ist a 5 channel machine laser receiver. The on-grade position is fixed at the centre of its reception window.

Product data

Multi-Sonic sensor

The UMS224 is a precise ultrasonic sensor for use on road construction machinery. This ultrasonic sensor measures the elevation over reference ground, curb-stone or string-line. If used over a string-line the UMS224 will detect both height and direction. The sensor has built-in LED height displays on the side and front, as well as LEDs for lateral adjustment.

Product data

Three axis slope sensor

The UNS300 is an external slope sensor in a heavy duty aluminium housing. The sensor measures the slope in all three axis X, Y, Z. It has a resolution of 0,1° and it is temperature compensated. The sensor will be mounted in cases, when the UMC4000 control box with internal slope sensor cannot be installed onto the moving blade.
