Abstract: An apparatus for emptying and filling horizontal freezers, which includes a first and a second chain actuator, the chain actuators being arranged parallel to each other and parallel to an y axis, the chain actuators having first and second ends, a sliding beam arranged between the first and second chain actuators nearby, or at, the first end of the first and second chain actuators, and a feeding arrangement for retracting the first and second chain actuators from an extended configuration to a collapsed configuration and for extending the chain actuators from a collapsed configuration to an extended configuration.
