Lever-Operated Mechanical Movement
The JJ arrangement uses a long operating handle beside the upright rack. The illustrated lifting point travels along that rack. Allow space for the lever movement as well as the load contact and base.
JJ rack jacks use a hand-operated lever to move a lifting point along an upright rack. Four catalog models share a listed 3 T capacity and 125 mm minimum lifting height, with different body and maximum lifting heights.
