ABSTRACT:
A device for opening a cylindrically bilateral filter canister, such as that houses the M98 chemical, biological, radiological filter for storage and transport. The filter canister is sealed with an epoxy-covered pull-cord that ends in an eye-loop. The device is disposed on a platform for the opening operation. The device includes a frame, first and second rollers, and a winch. The frame includes first and second support members. The first support member engages the platform and supports the second support member. The first and second rollers are disposed parallel to the platform to support the canister along its periphery. The winch includes a drum and a motor and is disposed on the frame. The drum engages the eye-loop. The motor turns said drum to receive the pull-cord from the canister.
