6. LIFT SUPPORTING STRUCTURE
• Top Mounting: The Plasma One 4 can be mounted from the top by using four 3 /
8
” threaded rods spaced
at 12 3 /
8
-inches [31.4 cm] wide by 23-inches [58.4 cm] deep. See Figure 4. The threaded rod must be
supported by a rigid mount and should not exceed more than 12-inches [30.4 cm]from the supporting
structure without cross bracing between the rods. If clearance allows, a “X-Y” or cross-supporting grid
structure is strongly recommended as shown in Figure 5a & b. The “X-Y” structure allows the lift
position to be adjusted side-to-side and front-to-back.

• Side Mounting: The Plasma One 4 lift can be mounted from the sides by using the four (4) 3 /

” - 16
bolts to attach the lift to the adjacent ceiling joist (or support structure). The lift top frame is designed to
fit within a standard 16-inch [40.6 cm] space between the floor joist. Spacers should be added to the side
of the lift top frame to avoid expanding the top frame when the bolts are tightened. The 14-inch outside
dimension of the lift top frame should always be maintained. See Figure 4.
