New track-type tractor

The D6R Series II track-type tractor features a new electronic C9 engine that meets emissions requirements for the US, Europe, and Japan, plus other improvements that increase productivity and reduce operating costs.

The Series II machine retains the best features of the D6R track-type tractor, including modular components for faster service, the elevated sprocket design, exclusive advanced modular cooling system, and a differential steering option.

The C9 engine features an electronically controlled, hydraulically actuated direct-injection fuel system that improves fuel economy and reduces emissions.

Air-to-air aftercooling also helps minimize emissions and boost engine performance. The engine is rated at 165 net hp (123 kw) when the machine is equipped with standard undercarriage. With XL, XW, or LGP configurations, net power is 185 hp (138 kw).

The torque divider and transmission are matched to the engine to optimize performance and component life.

The planetary powershift transmission now features load compensating shifting, which automatically adjusts the clutch engagement timing according to load factors.

This results in improved tractor performance and operator comfort during speed changes.

The D6R II has a spacious cab, isolation-mounted and pressurized to reduce sound and vibration.

The operator has clear views of the blade and ripper tip. The machine is equipped with a fully adjustable seat to reduce fatigue.

Ergonomically designed, pilot-operated controls for the blade and ripper help improve productivity. The differential steering system and electronic fingertip control clutch and brake aid maneuverability and control.

A newly designed instrument panel helps keep the operator informed, and the monitoring system provides instant feedback about operating conditions, as well as valuable information for diagnostics.

The tractor is designed for easy service. Most major components can be removed and installed as modules, reducing repair time.

Cooling system cores can be removed individually without removing the radiator, decreasing service time and increasing uptime.

The engine oil change interval is extended to 500 hr. Implement valves are easier to access. Pressure test points are provided for fast hydraulic and power system checks. When repairs are needed, the D6R II accommodates electronic diagnostic tools.

Pressure sensor also records temperature

An RTD temperature option has been added to this firm's line of pressure sensors.

The option utilizes a 0.1% DIN standard tolerance 100 ohm platinum RTD and is available on voltage or current output pressure sensors.

This option can be added to nearly all the maker's pressure models, regardless of range, including miniatures.

This capability is suited for uses that encounter extremes in temperatures such as natural gas compressor station monitoring.

Robotics manipulator arm features new wrist camera

A new wrist-mounted camera for the TITAN 3 manipulator arm is designed to improve operator view of the task being performed.

The monochrome or color camera is contained in an integrated titanium housing for maximum protection.

No external cabling is required because camera signals and power are routed though the TITAN 3 arm.

Video signals can be in NTSC or PAL format and are available at the TITAN 3 slave bottle.

Pressure release technology patented

A newly patented annular pressure release technology is designed to save offshore producers well-damage and rig-downtime costs.

The annular pressure release system (APRS) serves as a safety valve for relieving pressure caused by hot production fluids trapped between the outer wall of one casing string and the inner wall of another.

APRS is a thin metallic disk built into the outer wall of the casing coupling. The disk is calibrated to burst at a predetermined pressure and temperature threshold selected by the end user.

The threshold can be set high enough to allow for thorough well testing but lower than that required to collapse the casing string or otherwise damage the well.
