TECH UPDATE

RUBBER-TIRED LOG LOADERS

TECH UPDATE EDITOR: DIANE METTLER

arbrofer

Arbrofer offers the 125,000-lb AF-712 knuckle boom loader powered by a 247hp C-9 Cat engine. It has a large lifting capacity 9,300 kg at a 9.14 metre reach, can pull up to 150,000 lbs and has a boom reach of 42'.

The AF-712 has a hydrostatic swing, with a swing rate torque of 79,657 lbs ft. The hydrostatic transmission is engaged from the modulating system located inside the cab. The hydraulic motor is directly mounted on the five-speed semiautomatic transmission and allows traveling speeds ranging from 2.4 km/hr to 14.5 km/hr. All new, high pressure hydraulic controls increase the machine’s lifting capacity as well as provide higher lifting capacities and shorter cycle times.

The frame rails are made of high strength steel plates. Fastacting stabilizers mounted at the four ends of the chassis ensure good stability in all working positions and the log loader turns 360 degrees with the stabilizers in a raised position. The highvisibility cab is roomy, tilts 90 degrees forward and is equipped with front guarding. Options include butt ‘n top type boom, shortwood, treelength and butt ‘n top grapples, air compressor for trailer braking, fire protection package, and more.

Caterpillar

Caterpillar’s large line of rubber-tired machines offers customers versatility and variety. Wheel loaders range from compact to small, mid-size and large. Among these is the new H Series: the 950H, 962H, 966H, and 972H.

All the company’s loaders feature powerful Cat engines, including ACERT Technology, which reduces emissions at the point of combustion via a system approach. It allows engines to run cleaner because they burn fuel more precisely and more efficiently, while maintaining engine performance and offering reliability with durability. These engines are said to provide exceptional power, efficiency and controllability in millyard applications.

The H Series wheel loaders range in power from 216 hp to 307 hp and weigh between 40,202 lbs to 55,451 lbs. They have a breakout force of 136 kN to 230 kN. All feature a new loading sensing hydraulic implement system with simultaneous lift and tilt capabilities, new electro-hydraulic controls, and improved serviceability points. And the H Series is five per cent more fuel efficient than the previous model.

Forks are matched to the specific log loader making them the ideal total-system solution for log handling. Millyard forks feature a top clamp that closes between the tines, allowing the forks to close onto loads as small as a single log. This design is ideal for moving logs throughout the processing cycle and sorting.

Liebherr

 

Liebherr’s log loaders have been developed from the company’s many models of material handling machines, used worldwide in a variety of applications.

The dedicated machines are designed and manufactured for millyard and bush log handling, featuring heavy-duty undercarriage and axles.

The most popular model in Western Canada is the Liebherr A934 B HD. It is a rubber-tired machine with high traction and floatation Michelin or Bridgestone radials. It’s designed for pulling log trailers hauling up to 60 cubic metres of wood and is available with three different front attachments.

The shortwood front has a 7.6-metre boom with a six metre angle stick. A variety of dangle-type grapples is available and sized for the wood length and weight. It features 47’ of reach from the centre line of the machine. And it can lift a full grapple of wood at full reach with the outriggers down, 360 degrees, at 75 per cent of its total lift capacity and at 87 per cent of the hydraulic power.

The tree-length front has the 7.6-metre boom with a five metre stick and a 1.1 metre live heel attachment. Also available for tree-length applications is a butt ‘n top front with a heavyduty stick, specially designed to handle the rigours of side torque.

Tanguay

 

Tanguay offers two models of knuckle boom wheel loaders. Both models feature highly efficient and low fuel consumption engines with state-of-the-art hydraulics for smooth and fast loading cycles.

They are equipped with a proven transmission for economical and reliable trailer towing. The outriggers insure incredible stability, with full lift capacity of over 360 degrees.

The hydraulic cab riser brings the operator up over 18 feet from the ground and it’s controlled by an electro-proportional control valve for smooth operations. The large 52” x 60” cab has a safe rear entrance and it’s been engineered for safety and comfort. Wheel loaders come with a wide choice of boom configurations for handling all types of wood and can be custom designed on request.

The WL150 is a 55,000 lb loader with a lift capacity of 35,000 lb. It features: a 165 hp Isuzu Turbo diesel engine; 17.5 x 25 tires with optional 20.5; a six-speed powershift transmission; and up to 100,000 lb towing capacity.

The WL350 is a 75,000 lb loader with a lift capacity of 46,500 lbs. It features: a 215 hp Cummins QSB Electronic engine; standard 20.5 x 25 tires with optional 23.5; a six-speed powershift transmission; and up to 150,000 lbs towing capacity.

The Tanguay knuckle boom wheel loaders are designed and built in North America specifically for the forest industry, with easy service access and competitive spare parts.

Terex/Fuchs

Terex/Fuchs offers six powerful loader models, giving the customer the right machine for the right job: the MHL 320L, 331L, 340L, 460L, 434L and 464L. These fuel efficient loaders operate on a load sensing hydraulic system and are powered by high horsepower, efficient Deutz engines, which the company says allows operators to cut fuel bills in half.

The high volume tank, working with a separate hydraulic oil cooler, allows the loaders to run at a low temperature. All the machines travel fast, allowing them to load and offload, sort, stack and feed quickly, resulting in greater productivity.

The MHL 320L, 331L, 340L and 460L models feature adjustable cabs. When stacking or sorting, the cab can be elevated up to as much as 18’ to eye level. They range from the 41,900-lb 320L with a maximum lift of 18,000 lbs and a reach of 31’ to the 73,744 lb 460L, with a maximum lift exceeding 38,000 lbs and a maximum reach of 44.3’.

The MHL 434L and MHL 464L have fixed cabs. The 343L weighs in at 50,926 lbs with a maximum lift capacity of 26,000 lbs and a reach of 35’. The 464L weighs 84,878 lbs with a substantial lift capacity exceeding 40,000 lbs, with a reach of 36’.

Sennebogen

The latest generation of Sennebogen material handlers for the forest industry, the 723 and the 735, have rear pin-mounted booms, extra wide axles, longer wheelbases and larger pneumatic tires.

These specific design features provide optimum weight distribution, stability and a smoother ride in all “pick and carry” operations in the millyard or in the forest. For additional stability, the 700 series comes with a front dozer blade and can be ordered with both front and rear-mounted blades.

With the rear-mounted boom comes increased visibility on the right side, increasing safety, even in tight quarters. Both models of the 700 Series come with all-wheel steering and, in all wheel-drive mode, are driven by two variable speed hydraulic motors.

High lifting and loading capacities have been achieved by optimizing the boom positioning. The end result is productivity even when the loads are large and the reach is long.

The oversize swing bearing and high-capacity pump allow the operator complete control in the swing action, even under load.

The 800 Series, long on experience in the forest, is available in over 20 different configurations, both tracked and rubbertired depending upon the application. Sennebogen offers a range starting with the 821 weighing in at 44,000 lbs to the 870 weighing approximately 200,000 lbs. The company also offers a complete line of special models ideally suited to specific applications and unique situations particular to high-volume loading operations.
