It is strong, it is stable, and it has eight wheels.
The Eco Log 688 takes the step into the next generation and joins the pendulum arm harvesters in the G series. The new 688G also comes with several other improvements. With a new hydraulic system, new pumps and naturally equipped with Eco Log´s modern harvester cabin, the 688G now offers an even higher tractive force and strength than before – in the machine as well as in the already strong harvester crane that has now been lifted to yet another level.
In the development of our 688G Eco Log have introduced a lot of new technology – an updated transmission, a new hydraulic system and a new generation of pumps. These are large updates that generate both high tractive force and performance to the machine. Thanks to a new crane valve and an electrically controlled crane pump, Eco Log get more power to the crane that can work efficiently even on full reach. As a customer, you get a really strong all-round machine in the same class as the largest machines on the market, a machine that can be used for everything from bigger thinning.
To achieve maximum traction force, the transmission and powertrain have been developed by equipping the machines with a completely new transmission pump and motor. Depending on the conditions in the forest and what the operator prefers, you can choose between different selectable driving modes where there is also a boost function for the situations when you need that extra power.
New on the eight-wheeled harvesters is also variable pressure levels, which means that the pressures to crane and harvester head is automatically calibrated and adjusted. It means that the machine is working with different pressure levels depending on the situation and external conditions. One gets plenty of power in both machine and crane when needed but can also operate with significantly lower pressure and save fuel when possible. Since the pump pressure calibration is automatic, it also makes servicing easier, and you never have to control the pressure on the crane or harvester head pumps. The machine takes care of that.
Other improvements that have been made on the machine are, amongst others, better tilt angles on the crane base and a stronger oscillation frame lock that adapts automatically to both speed and crane position. Also, the machine’s design has been given a boost. Source
