AUTOMATED MASONRY SYSTEM

WARNING:
• DO NOT use damaged or deteriorated equipment.
• Begin assembly with leveling jacks and mud sills. Secure leveling jacks to mud sills.
• DO NOT use unstable objects under leveling jacks and/or mud sills.
• The footing must be sound, rigid, and capable of carrying the maximum intended load with
out settling or displacement.
• Use only leveling jacks (maximum extension of 12 inches) to adjust
to uneven surfaces.
• All tower sections must be secured together by threading connecting
bolt through nut in previous tower or base and tightening to at least
175 FT. LBS.
175 ft. lbs.
• DO NOT use tower if connecting bolt or nut is damaged and/or will
not tighten.
IMPROPER USE OF THIS EQUIPMENT WILL RESULT IN SERIOUS INJURY OR DEATH.
ASSEMBLY:
-
• Bracing must be used in the following man
ner:
1. A diagonal brace must be secured
between and perpendicular to pairs of
bases to ensure squareness. (Applies
to closed bay only.)
2. A diagonal brace must be secured
across the splice that joins the base to
the rst tower. (Applies to closed bay
only.)
3. A diagonal brace must be secured
between each set of towers. (Applies to
closed bay only.)
4. Two horizontal braces must be secured
between carriages. (Applies to open
bay only.)

WALL TIE AND HORIZONTAL BRACING DIAGRAM
• Maximum free standing height equals 3
times the smallest base dimension.
• When height exceeds 3 times the small
est base dimension, scaffold must be
restrained from tipping by factory approved
methods (see above diagram).
• Horizontal bracing is required in open bay
every 21' of height (see above diagram).
• For heights that require more than 9 towers
(63'), consult factory for additional diagonal
and horizontal bracing instruction.
• Before raising the platform, ensure towers
are plumb.
• Before raising, ensure the following:
1. The cable is free of any defects such
as kinks, broken strands, at spots, or any
other defect that could reduce strength.
2. Winch is securely attached to carriage with four connecting bolts.
3. The safety dog is present and operable.
4. The pinning device is present and operable.
5. Tender platform is pinned to carriage at each tower; retainer bolt is present on mason
platform.
• Install all guard rails, end guards, and toeboards prior to use.
• When "jumping" cable, the only approved method of blocking the load is with pinning device
located on carriage.
• After the cable has been placed in service and is under tension, the nuts on the 3 wire rope
clips attached to the cathead unit should be tightened to compensate for any decrease in
rope diameter caused by loading. This should be done before each use and after the initial
load has been applied.
-
• Heights greater than 125' must
be certied by a registered
Professional Engineer.
• Platforms rated capacity =
2,000 lbs. / tower. (Capacity
includes men, tools and ma
terials.) (An allowance of 4.2
lbs. / foot has been made for
boards.)
• Structural capacity based on a
4 to 1 safety factor.
• Cable capacity based on a 6 to
1 safety factor.

USE:
METAL CONDUCTS ELECTRICITY! DO NOT USE WHERE EQUIPMENT OR USER MAY
CONTACT POWER LINES OR OTHER LIVE ELECTRICAL CIRCUITS.
• Inspect scaffold daily and before each use.
• DO NOT alter or override safety devices under any circumstances.
• DO NOT use wire, rope, or any other type of tie down device to modify the intended function of safety dog, pinning device, winch, crank, or any other Mason-Jax component. If all
components are not functioning properly, product malfunction such as free wheeling descent
could occur.
• DO NOT use without guard rails or toeboards installed.
• DO NOT sit or stand on guard rails.
• DO NOT stand on or climb crossbraces.
• DO NOT use crossbraces for a platform support.
• DO NOT exert horizontal force on top of a free standing scaffold.
• DO NOT use boxes, ladders, or any other means to increase the working height.
• DO NOT overload - check with factory for safe working loads.
• DO NOT place loads cantilevered beyond outermost edge of tender platform.
• DO NOT apply shock load. When stocking materials, ease loads onto platform.
• Carriages and towers move in opposite directions. Keep body parts, clothing, materials, etc.
clear of these parts.
• Immediately replace a guard rail and toeboard after loading tender platform.
• Access scaffold platform only by independent scaffold stair tower, through building wall
opening, or by extension ladder. DO NOT CLIMB TOWER SECTIONS OR CROSS BRAC
ES TO ACCESS PLATFORM.
IN ADDITION TO THE ABOVE, FOLLOW ALL FEDERAL, OSHA, STATE AND LOCAL CODES
AND REGULATIONS FOR THE PROPER USE OF THIS EQUIPMENT.
