1. A container manipulation device, for the manipulation of a bulk material container comprising a bottom and side walls, the container manipulation device comprising:
a frame, configured to be provided on a hoisting device,
two container engagement members provided spaced apart on the frame, each pivotally connected to the frame by a slewing bearing connected to the frame about a respective transverse engagement member pivot axis, the associated engagement member pivot axis being the central axis of the slewing bearing, the pivot axes of the two engagement members being coaxial, wherein the engagement members are arranged for engaging the container there between,
two pivoting mechanisms, one for each container engagement member, arranged for pivoting the engagement members with respect to the frame between a first orientation of the engagement members in which the engagement members, in use, orient the container in an upright orientation wherein an upper side of the container faces upwards, and a second orientation of the engagement members in which the engagement members, in use, orient the container in an upside-down orientation wherein the bottom of the container faces upwards so that the container may be emptied, the pivoting mechanisms each including
an elongate coupler, pivotally connected with a first end to the engagement member about a coupler pivot axis located at a first distance from the engagement member pivot axis, and having a second, opposite end, and the elongate coupler pivotally connected with the first end to a rotatable inner ring of the slewing bearing,
an elongate rocker, pivotally connected with a first end to the frame about a rocker pivot axis (28), and with an opposite, second end pivotally connected to the second end of the coupler about a rocker-coupler pivot axis, and
an actuator for pivoting the rocker about the rocker pivot axis such that the engagement member pivots between the first and second orientation.
