LSL introduces latest SUB-FLEX system

Level Systems Ltd (LSL) has introduced its latest SUB-FLEX self-leveling system for use with all standard tracked excavators. SUB-FLEX is designed to extend the safe operating range of both new and existing excavators by maintaining a level operating platform on steep slopes with gradients of up to 24 degrees.

The system automatically levels the excavator’s cab and swing boom—independently of the tracks—to ensure safe and efficient distribution of weight on all types of slopes. The automatic leveling function works even while the excavator is moving, allowing operators to work in areas previously off-limits.

Hitachi Zaxis “Dash Three” Excavators


Hitachi has introduced its new Zaxis “Dash Three” excavators: ZX240LC-3, ZX270LC-3, ZX350LC-3, ZX450LC-3, ZX650LC-3 and ZX850LC-3. Enhancements added to these new excavators include Tier 3 engines, faster hydraulics, a redesigned cab, and a beefier undercarriage.

A completely redesigned cab offers an optional heated/air ride seat. Controllable speed in the hydraulic system makes the excavators easy to operate. But the biggest advance is said to be the faster hydraulic system, which boosts productivity by up to eight per cent. Drawbar pull, swing torque, lift capacity, and arm force have been improved, as well.

Blount acquires Sweden’s Votec Engineering

Blount, Inc recently acquired the manufacturing and marketing rights and certain assets of Votec Engineering AB of Söderhamn, Sweden, a manufacturer of forestry harvesting/processing attachments.

Votec has 11 models of harvesting attachments designed for all harvesting applications, and its processing heads can be mounted on excavators in addition to purpose-built forestry machines.

Votec is well known and has a reputation for advances in design, and for manufacturing efficient and productive processing and harvesting attachments, said Dennis Eagan, president of Blount’s Industrial and Power Equipment Group.

Volvo’s D Series features Automatic Traction Control

Volvo has introduced the Automatic Traction Control system as an option on its A25D and A30D articulated haulers. The system monitors wheel slippage and engages the 100 per cent dog-clutch locks when needed, allowing haulers the maximum drive when required.

With the ATC system, haulers can work in the best drive configuration for the prevailing ground conditions. The system reduces operator impact on
tire wear, mechanical fatigue and fuel consumption. Operators are able to concentrate on operating and hauling safely.

Caterpillar updates IT38G Series II Integrated Toolcarrier

Caterpillar has improved the IT38G Series II Integrated Toolcarrier, enhancing versatility, productivity and visibility. The medium wheel loader-based machine has been redesigned to provide excellent lines of sight to the quick coupler and work tools, and the number of work tools available for the machine has been increased as well.

Structural changes have increased full turn static tipping load by 14 per cent to 19,106 lbs. The effects are improved stability and greater work capabilities, without reducing responsiveness. Cat has expanded the line of buckets offered—the range now spans sizes of 2.75 to 3.5 cubic yards.

The machine still maintains key features, including 180 net hp, parallel lift linkages and integral quick couplers.

Tigercat adds 610 skidder to hydrostatic line

Tigercat has added the 173 hp 610 model to its line of hydrostatic skidders. The 610 uses the same electronichydrostatic drive control system found on all Tigercat skidders. With automatic variable speed engine rpm, the system is said to be extremely fuel-efficient and makes the operator’s job easier as there is no throttle control or gear shifting necessary when operating the machine.

The 610 is hinged with Tigercat’s signature centre section, which is constructed with thick steel plate, large pins and tapered roller bearings. The tilting cab accesses the hydraulic and drive line components. The 610 is available with a single or dual function arch and continuous rotation grapple. The seat and all controls are rotated 40 degrees to the right for reduced neck strain. Excellent visibility to the rear tires and the load makes the machine ideal in tight selective cut or plantation thinning
applications, says the company.

Opsal Steel purchases
logging rigging line

Opsal Steel Ltd has purchased I’Anco Products Ltd’s well-known logging rigging line. Opsal will continue to provide rigging shops throughout North America, Australia and New Zealand with the same top quality rigging products that I’Anco has supplied over the last 65 years. I’Anco has committed to expanding its conveyor chain and custom casting business, while Opsal continues to expand its exposure in the timber harvesting sector.

New leveling system means more control for Deere buncher operators

Loggers can experience a new level of performance with the introduction of the 909J and 959J track feller bunchers from John Deere. With their four-way leveling system and increased operator control, these machines are said to offer among the best-in-class combination of power and productivity.

“When it comes to working in steep slope and rough ground applications, the new John Deere J-Series feller bunchers provide unsurpassed stability with all-out performance that puts more wood on the ground,” says Elliott Little, John Deere product manager.

The 909J and 959J were designed with operator productivity and control in mind.

Leveling is possible up to 26 degrees forward, seven degrees rearward and 14 degrees from side-to-side. Both models feature a Total Machine Control system that enables operators to set the speed and acceleration of the tilt to match the application, terrain and capabilities, while providing constant position feedback. In addition, the redesigned cab features increased downward visibility for a clear view of the ground conditions below.

Power is another advantage of the new John Deere track feller bunchers, the company says. These machines provide outstanding saw blade power with quick recovery time and 294 SAE gross horsepower. The hydraulically driven cooling fan optimizes horsepower and increases fuel efficiency by running only when it’s needed. The fan is fully reversible and automatically blows out debris for better airflow into the engine, making it run cooler and more efficiently.

Beyond the standard felling head offered, optional heads are available to match the specific logging application. Two felling head options are available on the feller buncher models (FS22B and the FR22B), and the 909J model can be custom built for harvesting applications with a woods-ready harvesting boom and optional Waratah processing heads (models HTH622B or HTH624).
