Abstract: The invention includes improvements in the device and method for lifting objects, such as bulk bags, in an area of a building with low headroom constraints. Among the many improvements of the hoist arrangement is a movable cart and frame assembly that is mounted to or between various I-Beam configurations of a hoist structure, such as a bulk bag unloader, so that the object being lifted can be raised higher under its overhead hoist frame. By reducing the height requirements of a standard hoist, which can often take up as much as 15? to 24? of space between the I-Beam and object being lifted (such as a bulk bag) a user may now use a taller bulk bag or other object with a greater capacity. In most states, highway trailers are limited to hauling a maximum load of approximately 44,000 pounds. The addition of 12? to 24? of extra lifting height can often be the difference between filling a bag to 2,000 pounds instead of a lesser amount such as 1,500 pounds.
