The Siemens MWL is a mechanical calibration weight lifter for Siemens MSI, MMI, MBS, MCS, and MUS belt scales. The MWL mechanically raises and lowers the static weights and stores them above the belt scale calibration arms, so the operator can lower and apply them safely without leaning into the conveyor.
The MWL is mechanically operated, and can apply weights up to 750 pounds. The crank handle uses 12 rotations for full range of motion, and can be removed and stored for safety with a locking ball-pin that secures the MWL when it's not in use.
