Common System Arrangements
Joyce jacks, miter gear boxes, couplings and motorized ComDRIVEs® can be used in a number of system arrangements. Several are shown here.
Because jacks selected for systems have uniform lifting speeds and are fully synchronized, unevenly distributed loads can be raised, lowered, and positioned in unison. Jacks of differing capacities may be used in the same system as long as driven shafts turn per 1" of travel are the same.
Arrows indicate the rotational direction to raise the load.
