FIG.11-TOE PLATE DOWN
Figure 11 through 15 help to describe how the portable unit works
When the lift is at the bottom the Lower Toe plate is down (Fig.11), the Upper Toe plate is up with the "T" Roller Bar on the Upper Toe plate compressed (Fig.12)
When the lift begins to rise the "T" Roller Bar on the Upper Toe plate un-compresses and the Lower Toe plate rises to the closed position
FIG.12-"T" ROLLER BAR COMPRESSED
FIG.13-ACTUATOR BAR CONTACTING CAM AND "T" ROLLER BAR RISES ABOVE THE GUIDE PLATES
When the lift nears the top the Upper Toe Plate Cam Actuator Bar contacts the Cam and the "T" Roller Bar rises above the guide plates (Fig.13) allowing the Upper Toe plate to begin folding down (Fig.14)
FIG.14-UPPER TOE PLATE UNFOLDS
The lift stops electrically by activating the limit switch plate, the Upper Toe Plate folds down to the landing position (Fig.15)
FIG.15-TOE PLATE OPENED FOR EXIT
FIG.16-BOTTOM ROLLER GUIDE PLATE
Follow the next steps if you have to change the height requirement of your portable unit
The electrical limit switch stop for the upper landing is controlled by adjusting the Upper Limit Adjusting Bracket as described in the Trust-T-Lift Installation Manual on page 2-7 Fig.17
For the Upper Toe plate to open at the required height, the height adjustment plates must be adjusted
FIG.17-CAM "T" BRACKET & ROLLER GUIDE PLATE RAMP
The Bottom Roller Guide Plate (Fig.16 Part A), Cam "T" Bracket (Fig.17 Part B), and the Roller Guide Plate Ramp (Fig.17 Part C) are permanently attached to the Side Cam Assembly, the only plates to be removed are the spacer plates in-between which vary based on the size of the lift
FIG.18-REMOVE ANY UNNECESSARY SPACERS
� The Roller Guide Plates are held in place with a �"X�" set bolt, loosen them off to remove the unnecessary spacers (Fig.18)
FIG.19-SLIDE DOWN SPACERS
After removing the unnecessary spacers slide down the spacers above as well as the Guide Plate Ramp and the Cam "T" Bracket (Fig.19)
Retighten all of the set bolts to set in place
Once the plates are adjusted properly the Upper Toe plate will open at the preset upper landing
A 28" travel lift can be adjusted to stop at 1" increments between 23" and 28"
A 52" travel lift can be adjusted to stop at 1" increments between 23" and 52"
If your needed height requirement isn't available in the ranges given above give RAM Manufacturing Ltd a call to inquire about a custom height lift
