Each box of photovoltaic module weighs about 910kg. In most cases, the photovoltaic modules transported by vehicles are transported in stacks of photovoltaic module packaging boxes, with the carriages placed side by side in 2 rows.

Under the conventional condition, a forklift can be adopted for unloading under the condition that the terrain address condition allows; under the condition that the forklift cannot be used due to poor terrain conditions, the crane is basically used for unloading, and when the crane is used for unloading, the following problems are caused:

1. when the soft hanging belt is used for lifting the packing box, the unloading mode is basically that the packing boxes with single-row assemblies are overlapped, and two rows/multiple rows cannot be lifted at the same time, so that the unloading can be completed only by lifting at least twice. (this is because when two rows of boxes are lifted by the sling, the boxes will tilt/swing to the middle due to the gravity of the boxes and the deformation of the sling)

2. Because the crane is unloaded the in-process because of box gravity and suspender deformation, lead to the suspender to tighten the extrusion to photovoltaic module packing box, probably lead to the photovoltaic module atress deformation damage in the packing box, increase unnecessary economic loss.
