Page 7: Centre Of Gravity Coordinates
5 - TRANSPORTE Y MANIPULACIÓN ● Discharge via forklift truck: Centre of gravity (mm) Weight The unit is designed to be transported safely by using a forklift (kg) truck. The forks of the forklift truck must come in on the side of the unit, ensuring that the centre of gravity of the unit remains within the forks, because a misbalance in the transport may cause the unit to turn over and fall from the forklift truck. -
