Abstract

A drive system for a mixer barrel for absorbing weight of the mixer barrel (1). The drive system communicates with a base (5) via a weight supporting element which supports the mixer barrel (1) and enables relative movement therebetween. The weight supporting element comprises at least one distortable elastic element (28, 29, 30, 39) enabling the movement between the drive system and the base (5). The at least one elastic element (28, 29, 30, 39) supports the weight of the mixer barrel (1) above the at least one elastic element (28, 29, 30, 39). The drive system (4) has at least one component (36) which limits movement of the drive system (4) and increases a distance between the drive system (4) and the base (5) such that a torque strain on the drive system (4) is braced by the base (5).
