Gremo Forwarder 1350VT
Gremo Forwarder 1350VT - Full pulling force and full speed. Without moving a finger.
The Gremo forwarder 1350VT is equipped with a continously working and variable speed hydrostatic transmission called Gre- VT (Grevete). Gre- VT is another leap forward in technology that Gremo has been the first to introduce on forestry machines. The unique transmission cuts the working cycles and by that increases performance and profibility. The hydrostat pump drives two hydrostat motors mechanically connected to the cardan shaft via a gearbox.
The driver does not have to shift gear, but can select the speed range, either 0-11.8 km/h or 0-25 km/h. Driving position 1 has always both motors engaged. This position is selected, if the speed should not exceed 11.8 km/h. In driving position 2 both hydrostat motors are still engaged from start, but the larger of those two is disengaged automatically as soon as the speed exceeds 11.8 km/h. Engaging and disengaging are controlled by GreControl, a software developed by Gremo.
The unique feature with this system is the fact that the Gremo 1350VT is able to run at 0-25 km/h without being interrupted by gear shift and with maximum pulling force. Thus it is possible to start with maximum pulling force even in driving position 2 The pulling force amounts to fully 18.4 kN, and the system submits higher pulling force across the speed range.
But to make the whole thing really worthwhile a big and powerful Diesel engine with high torque is called for. Gremo has chosen a step 3 common-rail Cummins 6-cylinders with 6.7 litres cylinder capacity. It develops 191 HP already at 1700 revs and delivers incredible 900 Nm at low 1200-1475 revs. It isby the way the same engine installed in the Gremo 1050H harvester, but there with 220 HP.The engine in the 1350VT is limited to 1700 revs. to save fuel. More power should not be necessary anyway.
In order to facilitate the cleaning of the radiators and to save fuel the cooling fan is driven by a hydraulic motor. The fan speed is adjusted to the cooling requirements and is controlled by GreControl. Every 30 minutes it reverses the fan rotation for 10 seconds to blow-off the radiators.This gadget has recently also been added to the 1050H harvester.
The boom pump has 145 cc volume and is electronically controlled via GreControl. This means that you can choose different flow rates at pre-determined speed to suit different working tasks, boom types and ways of driving. This offers possibilities for lower fuel consumption.
Gremo 1350VT , 1050F and 1050H are furnished with the same type of drivers cab featuring Gremo´s product distinguishing mark - the visibility.Most people say that the close range visibility and the easy-view working area are unmatched. Good visibility less strains the eyes, which means a lot for the driver´s capacity during his working day.
