A bulk bag discharge assembly comprising a main frame assembly and a bag conditioning assembly. The main frame assembly defines a bulk bag receiving region having a discharge support base structurally configured to receive a bulk bag thereon for discharging. The bag conditioning assembly comprises opposing conditioner frames, each having a proximal end, a distal end, and an impact face, and at a proximal end, pivotably coupled to the main frame assembly. A powered cylinder is pivotably coupled to the main frame assembly at a first end, and to the first conditioner frame at a second end. The conditioning assembly is structurally configured to impact a side of a bulk bag positioned on the discharge support base, without impacting a bottom of a bulk bag, wherein the distal end of the first conditioner frame is directed at least partially in an upward direction within the bulk bag receiving region.

A pallet lifter for use with a crane enables lifting of materials on a pallet, and then unloading of the materials at one or more locations, such as on a roof of a building. The pallet lifter may include a cage or a retainer frame that contains the material, with a pusher of the lifter used to push out individual portions of the materials. The pusher may unload the material from the top of the pallet of material, such as by sliding it down a ramp. The pusher alternatively may unload the material from the bottom of the stack on the pallet, by pushing it through a slot in the cage. For top-unloading embodiments the pallet lifter may include an assembly for changing the position of the pusher relative to the frame and the pallet, for example moving the pusher downward layer by later as the materials are unloaded.
