Ponsse

All Ponsse forwarder models have the power required to cope with extremely varied conditions and even the most difficult terrain, says the company. The favourable ratio between net weight and load carrying capacity, the smallest turning radius for their size class, according to the company, as well as proportions that distribute the weight evenly over all tires make these forwarders very productive.

The Buffalo King is Ponsse’s largest, followed by the Buffalo, Elk, Wisent and Gazelle.

The Buffalo King can carry nearly its own weight in wood. The 18-tonne Buffalo King offers its operator a luxurious cab, the powerful Ponsse K100 loader, ample load space, an efficient and powerful Mercedes-Benz engine and a sturdy structure ready for the most demanding harvesting conditions.

The Buffalo is 9,395 to 11,250 mm in length and 2,670 to 2,960 mm wide. It can carry 14,000 kg, with a load space length of 4,240 to 6,100 mm and has a 7.9 mm reach.

The Elk forwarder has a carrying capacity of 13 tonnes. It’s designed for extremely challenging terrain. The Elk is 9,120 to 9,725 mm (+700 mm adjustable extension) in length and 2,670 to 2,970 mm wide (depending on tires).

The Wisent is 9,050 mm in length, can carry 12,000 kg and has a load length of 4,500 mm. And the Gazelle has the same reach as the Buffalo and Wisent, but is lighter, at 11,900 kg, and with a carrying capacity of 10,000 kg.

Tigercat

Tigercat builds three forwarders for extreme duty applications. They offer tough construction, excellent cooling capacity and great stability when traveling and loading.

The 1055 forwarder is designed with a strong frame, large pins and steer cylinders and a durable centre section with tapered roller bearings in the articulation and oscillation joints. It’s powered by a 201-hp (150 kW) Mercedes 906 Tier II engine. Electronic canbus control technology governs machine functions and the extra large cab with extended windows offers improved visibility when unloading.

The 1055 is equipped with 14-tonne rated bogie axles and all control valves are located in a single compartment accessible at ground level. And the operator has easy access to engine and hydraulic components through tilting engine enclosure and tilt cab.

The more powerful 1065 is designed for maximum stability and has many of the same features as the 1055, but is powered by a 228-hp (170 kW) Mercedes 906 Tier II engine and equipped with 18-tonne rated bogie axles. Like the 1055, wagon options can be configured for 4.8 m lengths or double bunk 3 m logs.

Designed for the tough final fell applications in extreme terrain, the 50,370-lb 1075 is equipped with a 241-hp (180 kW) Mercedes 906 Tier II engine and 20-tonne rated bogie axles.

TimberPro

TimberPro has recently been working on a totally new design for its wheeled forestry equipment. The goals were to have complete visibility to the boom side of the cab with the engine mounted in the rear, a larger, quieter and more comfortable cab, gull wing access for maintenance and repair and new booms with more lift capacity with the stick cylinder mounted on top for less possibility of damage.

This all had to be done on a rotating platform with a radius of no more than 62” to retain the no tail swing feature. This has all been accomplished on the forwarder, feller buncher and both the clambunk and grapple skidders, which all use the same rotating upper platform along with engine options from 250 to 300 hp. And the two-tone colour options—red, blue or green—have made the machine appealing as well.

Trans-Gesco

Powered by a 400-hp Cummins QSM electronic engine, the Trans-Gesco TG88 has a 25-ton payload capacity and a wood basket designed to maximize payload for various log lengths up to 35’. The heavy-duty frame and robust loader is controlled by state-ofthe-art load sense hydraulics and is available with an optional live heel for long length. The proven 100 per cent hydrostatic traction and steering assist offers superior maneuvrability, and a huge 160,000 lbs of tractive effort and a wide choice of track up to 60” wide for extremely low ground pressure. The TG88 is also available with a clambunk forwarder or grapple skidder configuration.

Valmet

Komatsu Forest’s new Valmet 840.3, 860.3 and 890.3 series ergonomic and technical advances push productivity even farther. Powered by fuel-efficient Tier III Sisu diesel engines, these big machines move timber even faster.

The six- or eight-wheel drive, 16-ton capacity Valmet 860.3 machines are maneuverable all-around performers with a sixcylinder, 190-hp engine and 590 ft-lb (800 Nm) torque at 1,500 rpm. They feature the CRF 10 boom with longer 25.6’ (7.8 m) reach and 28,544 ft-lb swing torque.

The 20-ton, 890.3 are powered by a 230-hp engine, with 738 ft-lb. (1,000 Nm) torque at 1,500 rpm. These eight-wheel drive machines feature a strong, sturdy CRF 14 boom—no other forwarder reaches farther, according to the company.

Inside, the new “dot-three” series machines have more cab comfort, better visibility, and improved convenience, making longer, more productive work shifts less stressful. The cab is redesigned with attention down to the smallest detail. Frequently used buttons are placed more accessibly. Lower panel profiles improve operator sightlines in all directions. Cab windows feature integrated sunshades. The easy-to-use MaxiForwarder system simplifies operation and maximizes operator efficiency.

The machines feature Valmet’s exclusive ProTec, completely protected hose passage between the boom tip and grapple.

New braking technology effectively dampens grapple swing. It also has a specially designed rotator. ProTec likely increases operator productivity by more than 10 per cent while reducing snag hose breaks by 20 per cent. Valmet equipment gets to and from the landing fast. Its unique articulated design provides excellent stability and allows for tight and safe turns.
