Boom and Terminology

The DELTA FORCE boom, also named DDZ, DDY or DDV, is pendulum suspended in a strong and stable parallelogram-
shaped boom lift (ParaLift).
• DDZ type: Fully hydraulic operated with all functions controlled via the direct hydraulic system (DH).
• DDY type: The hydraulic functions for raising / lowering and folding / unfolding of the boom are operated via the
tractor hydraulics.
• DDV type: Same as DDZ, but with the hydraulic boom tilt cylinders replaced with steel wires for easier boom folding.
