Abstract
A bag lifting and emptying system (100) may include a rupture mechanism (120) for the bag (105), an attachment mechanism (110) for the bag (105), and a hoist (130)connectable to the attachment mechanism (110). The rupture mechanism (120) may be configured to rupture a bottom portion of the bag (105), when the bag (105) is lowered onto the rupture mechanism (120), so as to cause the contents of the bag (105) to be transferred from the bag (105) into a receptacle (137). The attachment mechanism (1 10) may be configured to releasably attach to the bag (105). The hoist (130) may be configured to lift the bag (105) and subsequently lower the bag (105) onto the rupture mechanism (120).
