A lifting attachment for lifting one or more containers, comprising a lifting attachment frame and an arm on each end of the lifting attachment frame, wherein the arm comprises an upper locking mechanism and a lower locking mechanism. Each arm further comprises a pivotable extension connected to an actuator, wherein a proximal end of the extension comprises a pivot point connecting the extension to the arm and a distal end of the extension comprises a support portion, wherein in a resting position the distal ends of the extensions are turned to move the support portions to each other and in an operating position the distal ends of the extensions are turned downwards for supporting the container from its side.

Lifting attachment for lifting containers

A hoisting mechanism of a crane comprising at least one rope drum for a hoist rope, at least one hoist motor for driving the rope drum, a gearing coupled between the rope drum and the hoist motor, and having an input gear on the hoist motor side and an output gear on the rope drum side, and a brake for braking the input gear. The gearing has a differential to which a first input gear and a second input gear are arranged, wherein the first input gear and the second input gear are coupled to each other and further coupled to the output gear, wherein a first hoist motor connected to the first input gear, and a second hoist motor connected to the second input gear are arranged, and wherein the first input gear and the second input gear have unequal total gear ratios relative to an output shaft. The invention also relates to a method for operating this hoisting mechanism.
