ABSTRACT:
An apparatus for transferring toxic waste liquid directly into a 55 gallon waste drum includes a mobile drum cradle that lifts the drum so it can be moved to a container presently holding the toxic liquid. A vacuum is produced in a transfer reservoir, and an inlet valve of the tank is opened and a dump valve of the tank is closed. The vacuum draws waste liquid through a tube and the inlet valve into the transfer reservoir until a full condition is sensed. The vacuum then is released, the inlet valve is closed, and the dump valve is opened, dumping waste liquid from the transfer reservoir through the dump valve directly into the drum. This procedure is automatically repeated until all of the waste liquid is transferred or a drum full condition is sensed. The drum is then carried to a disposal site by the mobile drum cradle.
