PLEASE READ THESE INSTRUCTIONS COMPLETELY
BEFORE USING PROCTOR WALL JACKS
|
The Proctor Wall Jack is a lightweight wall lifting device. Always use a minimum of two Wall Jacks to raise a wall. The 16' Wall Jack has a 1,000 pound lifting capacity. Capacity for the 20' and 23' Wall Jacks is 500 pounds. The Jacks collapse for storage and transportation, but the tubes must be pinned in the extended, working position for lifting.
|
FRAMING FOR TILT UP WITH PROCTOR WALL JACKS:
When the wall is being framed, preparations must be made to prevent it from sliding off the subfloor during the lifting process. This can be done satisfactorily by using light metal strapping, approximately 24-26 gauge, as shown in Figure 1. Use a minimum of three straps on any wall, placing them near the ends and in the center, and about 8' on center on any wall longer than 20'.

SETTING THE WALL STOP:
The Wall Stop is designed to hold a 2 x 4 or 2 x 6 frame wall in an upright position after it has been lifted. Pin the tubes in their extended, working position using the 1/2" pin attached to the lower tube. The Wall Stop should be set at the proper height and firmly tightened prior to placing the Wall Jack into its vertical lifting position. For proper height settings, use the chart on the label on the lower tube, or measure the height of the wall at the lift point and then multiply by 1.45 to obtain the setting.
| Example: 96" high wall x 1.45 = 139" or 11'-7" from Wall Jack Hinge to underside of wall stop. The 1/2" pin must be securely through both sides of both tubes before the lifting process begins. |
Never raise any wall higher than the rated wall height for the Wall Jacks you use.

CARE OF THE CABLE:
The galvanized aircraft cable installed on every Proctor Wall Jack has a minimum breaking strength of 2800 lbs. Care must be taken in handling the Wall Jacks to prevent kinking of the cable or breaking of the strands. The cable should be carefully wound onto the drum of the winch, one even layer at a time, during the lift; it should be stored the same way between uses. Cable should be inspected frequently for broken strands or other damage, and it must be replaced when strands are broken or when the cable is bent, frayed, flattened, kinked, or otherwise damaged. In use, the cable should run free of all contact with the Wall Stop, Handle-nut, Bolt, or other Wall Jack part. Cable should be placed on the inboard side of the Wall Stop projection as shown in Figure 2. Never proceed with a lift when the cable is rubbing any part of the Wall Jack or any other object.
