1. An apparatus for transporting a load, comprising:
a frame displaceable along a rail;
a load carrier which is rotationally mounted on the frame to be rotated around a horizontal axis;
an adjusting motor arranged to rotate the load carrier relative to the frame around the horizontal axis;
a rotation blocking device for blocking a rotational movement of the load carrier with respect to the frame in a braking operation mode of the rotation blocking device;
a decoupling means configured to decouple the load carrier from the rotation blocking device and/or the frame from the rotation blocking device, such that a limited amount of movement of the load carrier and/or the frame with respect to the rotation blocking device is allowed in the braking operation mode of the rotation blocking device, and
a resilient member for resisting at least part of said movement of the load carrier and/or the frame with respect to the rotation blocking device;
wherein the resilient member is configured for resisting a rotational movement of the load carrier with respect to the frame around the horizontal axis, as part of said limited amount of movement; and
wherein the decoupling means comprises mounting holes, provided in the rotation blocking device for connecting the rotation blocking device with the load carrier and/or the frame, the mounting holes being elongated in a tangential direction around the horizontal axis for allowing said rotational movement.
