Omnibus Control Combines Multiple Functions in One Joystick

The joystick controller for Vac-Con and Xcavator machines provides added convenience in the operation and maintenance of hardworking rigs.

The Omnibus control system for Vac-Con combination and Xcavator (hydroexcavating) machines puts all vacuum and water system functions on a joystick-style controller for one-hand operation.

The system consolidates all the separate switches, levers, instruments, controls and system monitor on a clean panel. Controller area network (CAN) technology substantially reduces the complexity of the electronic and hydraulic systems.

“The configuration eliminates 5,300 feet of wiring — more than a mile — and 124 wiring connections,” says Tom Jody, marketing manager. “Fewer wires and connections mean fewer opportunities for failure points and greater simplicity. And because the cost of technology has come down, this system is surprisingly affordable.”

Jody notes that joystick-style controllers have become popular on a variety of equipment, including construction machinery. The Omnibus control handle is mounted to the top of the truck’s hose reel panel. The monitor screen beneath the handle replaces the instrument panel found on conventional trucks.

On the vacuum side, the handle controls chassis engine rpm and regulates boom movement. The operator twists the handle to telescope the boom, pushes forward or pulls back to lift or lower, and moves side to side to swing the boom left or right.

On the water side, the handle controls starting and stopping of the auxiliary engine that drives the pump, regulates engine rpm to adjust pressure and flow, controls hose reel articulation, activates the outrigger leg that supports the reel, and controls the extension and retraction of the hose.

Operators can use the monitor to program specific functions. For example, if the hose retract speed is set at 25 percent of maximum, then the operator can push forward on the handle to increase the speed to the preset limit.

“Proportional hydraulic valves with a central control unit enable operators to make very accurate and precise movements,” Jody notes. “It puts the power exactly where the operator needs it. That saves time on the job, in turn saving run time and conserving fuel.” In addition, the system provides wide flexibility to expand control and diagnostic capability simply by adding sensors or controllers.
