The apparatus consists of a support frame, C, to hold apart the strap handles, d, of a bulk bag for aggregate or waste. This enables the removal of material, easily pulling down the top of the bag as emptying proceeds while holding the bag open. The frame has four identical bars which link together by loop catches (see figure 4). The bag strap handles may be threaded onto the loops (see figure 7), which are then locked into each other with the loop catch to form the frame. The frame is easily assembled and disassembled with no loose parts. Four identical leg components (see figure 9) may be included to support the frame so that it can be used to hold a bag open enabling access for refilling also. The device is easily assembled and disassembled making it portable. |
