Hoisting frame and method for hoisting containers

Abstract

The invention relates to a hoisting frame, specifically for hoisting containers, including a longitudinally adjustable beam having a plurality of outer pickup elements arranged at ends of the beam and inner pickup elements arranged near a center of the beam. The inner pickup elements are connected to the beam and moveable in longitudinal direction. The inner pickup elements are moveable along the beam in pairs and are arranged in pairs on a saddle placed transversely on the beam and slideable therealong. The invention also relates to a method for transporting containers by use of such a hoisting frame. The method steps include picking up at least two adjacent containers at a first location, lifting the containers and moving them through the air to a second location, and lowering the containers at the second location. Additionally, at least one of the containers is moved in a longitudinal direction relative to the hoisting frame between lifting and lowering thereof. The hoisting frame of the invention allows containers stacked with various spacings to be transported in double-acting operation.
