<p>The emptying process involves using the pump (410) of an emptying device (100) to create a maximum pressure, suitable for the dustbin of normal weight. The hydraulic or pneumatic motor (110) runs at this pressure unless the dustbin exceeds a certain weight, in which case the pressure is reduced to a lower level. A pressure raising device (300, 310) is fitted between the pump and the hydraulic or pneumatic motor.</p> |
