Tech Update - Forwarders

PonssePonsse

Ponsse is said to be the first forest equipment company to introduce a forwarder with active damping. The highly popular active damping system used in the Ponsse Ergo and Bear harvesters has now been introduced in forwarders, increasing the stability of driving and significantly reducing sideways movements affecting the operator.

The unique active damping system developed by Ponsse effectively eliminates vibration caused by uneven terrain and keeps the cab in a vertical position. The system enables quick movements and provides the operator with first-rate working conditions, the company says. The cab remains in a vertical position within the active damping system's movement range, particularly on slopes, increasing comfort in loading.

The six-wheel Ponsse Buffalo ADS forwarder is now equipped with the active damping system patented by the company. The new forwarder combines the agility of a six-wheeler and the comfort of an eight-wheeler achieved through its active damping system. www.ponsse.com

TigercatTigercat

Tigercat builds three forwarder models ranging from 11 to 20 tonne capacity.

Smallest in the range is the 1045B, a heavy-duty11-tonne forwarder with a 201 hp Mercedes 906 engine. Next is the 1055B, powered by a 228 hp Mercedes 906 Tier III engine. The 1055B has a 14-tonne load capacity. This is an all-around forwarder, well suited to thinning or final fell applications.

Tigercat's highest capacity forwarder is the 20-tonne 1075B. Built for final fell applications, extreme terrain and forwarding heavy timber over long distances, the 1075B is powered by the 275 hp Mercedes 906 Tier III engine.

The wide super-duty 20-tonne bogie for the 1075B provides extra flotation and reduced ground pressure when equipped with tracks and eliminates bogie-lift on steep slopes. Additionally, with Tigercat's unique centre section design, the 1075B does not require an oscillation lock, allowing the operator to reach out and pick up a load of logs while the machine is still in motion for improved productivity. 

Various bunk and wagon options are available to customize the Tigercat forwarders to specific applications, together with optional sliding bunks for added versatility. The 1055B and 1075B are also available with optional expanding bunk systems.

LogsetLogset

Logset forwarders are designed to withstand the harshest conditions and are built from components from leading suppliers. All Logset forest machines are equipped with Agco Sisu Power's efficient, low fuel consumption common rail engines, Loglift-loaders and NAF drive train. The main suppliers of hydraulic components are Sauer and Rexroth.

Logset forwarders have spacious and modern cabs with excellent sound insulation, the company says, and visibility from the cab is unobstructed in both the drive and load modes. Titan forwarders are equipped with Logset's Total Operation Control (TOC) system. The TOC controls the main functions, such as the engine, crane, transmission, lights and air conditioning, cruise control as well as some optional functions.

Agco Sisu Power has developed custom made engine software for Logset in accordance with the requirements of their forest machines.

TimberProTimberPro

The TimberPro TF800B series is among the most versatile forwarders on the market today, says the company. What makes the TF800B so versatile is its ability to work 360 degrees all around the machine. The 360 degree work area allows the operator to easily fix or mat heavily used skid trails and retrieve wood from difficult-to-reach areas. This same 360 degree work area allows the TF800B – COMBO machine to be both an effective harvester and forwarder.

The TimberPro TF840B forwarder with its powerful drive train can be transformed into a clambunk skidder for tree length operations. It is also available with an optional 4' longer rear frame and custom long length wood basket to forward long length logs.

The cab forward design and centered steering joint allows the TF800B series to have a very tight turning circle with no off-tracking. The operator swings with the boom, effectively making the machine an extra loader at the landing.
