A lifting arrangement of a transport cart of a storage and retrieval system, the lifting arrangement comprising: a lifting drive shaft having a first end and a second end; a lifting driving arrangement (30, 32) connected to the lifting drive shaft, for rotating the lifting drive shaft; a first and a second eccentric (34, 35), the first eccentric being fixed to the first end of the lifting drive shaft and the second eccentric being fixed to the second end of the lifting drive shaft; a first and a second linkage system (40, 60), each having a first part (41, 61) and a second part (51, 71) distant to its respective first part, the second part of the first linkage system being connected to the first part of the first linkage system via a first link arm, and the second part of the second linkage system being connected to the first part of the second linkage system via a second link arm, the first and the second parts (41, 61, 51, 71) each being rotatably mountable to a chassis of the transport cart, whereby a periphery of the first eccentric bears against the first part of the first linkage system and a periphery of the second eccentric bears against the first part of the second linkage system so that when the lifting drive shaft rotates the first and the second eccentric (34, 35), the periphery of the first eccentric urges a reciprocating movement onto the first linkage system and the periphery of the second eccentric urges a reciprocating movement onto the second linkage systems so that the respective first and second parts (41, 61, 51, 71) turn back and forth around an axis oriented substantially parallel to an axis of the lifting drive shaft, characterized by that the first part of the first linkage system defines a first opening that encloses the first eccentric, and the first part of the second linkage system defines a second opening that encloses the second eccentric, and whereby the periphery of the first eccentric bears against a periphery of the first part of the first linkage system defining the first opening, and the periphery of the second eccentric bears against a periphery of the first part of the second linkage system defining the second opening. a lifting drive shaft having a first end and a second end; a lifting driving arrangement (30, 32) connected to the lifting drive shaft, for rotating the lifting drive shaft; a first and a second eccentric (34, 35), the first eccentric being fixed to the first end of the lifting drive shaft and the second eccentric being fixed to the second end of the lifting drive shaft; a first and a second linkage system (40, 60), each having a first part (41, 61) and a second part (51, 71) distant to its respective first part, the second part of the first linkage system being connected to the first part of the first linkage system via a first link arm, and the second part of the second linkage system being connected to the first part of the second linkage system via a second link arm, the first and the second parts (41, 61, 51, 71) each being rotatably mountable to a chassis of the transport cart, whereby a periphery of the first eccentric bears against the first part of the first linkage system and a periphery of the second eccentric bears against the first part of the second linkage system so that when the lifting drive shaft rotates the first and the second eccentric (34, 35), the periphery of the first eccentric urges a reciprocating movement onto the first linkage system and the periphery of the second eccentric urges a reciprocating movement onto the second linkage systems so that the respective first and second parts (41, 61, 51, 71) turn back and forth around an axis oriented substantially parallel to an axis of the lifting drive shaft, characterized by that the first part of the first linkage system defines a first opening that encloses the first eccentric, and the first part of the second linkage system defines a second opening that encloses the second eccentric, and whereby the periphery of the first eccentric bears against a periphery of the first part of the first linkage system defining the first opening, and the periphery of the second eccentric bears against a periphery of the first part of the second linkage system defining the second opening.
