e ) Line up the caster holes with the brake shoe hole and brake pedal hole.
f ) With the washer on the bolt-side of the caster assembly, reinsert the longer axle bolt through the brake pedal,
brake shoe, and caster. Reapply the axle nut at this time.
g ) Using a 3/4-inch wrench and 3/4-inch socket and ratchet, securely tighten the caster nut.
h ) Repeat steps a) through g) to install the remaining caster brakes.
3. V-Groove Track Installation
a ) The exact span of the crane may vary from the design span. Install the full length of the track on one side, making
sure that the track is straight and level. Fasten V-groove track to the floor using 3/8-inch lag bolts and suitable
anchors. (For track supplied by Spanco, use a bolt in each hole. Otherwise, space bolts approximately three feet
apart on each side of the track in a staggered arrangement.) Use shims or grouting as required to keep the track
level and alignment pins at joints to keep the track true. End stops are required at each end of both tracks.
b ) Lay one or two sections of the opposite side of the track at the design span, assemble the crane on the tracks
following the assembly instructions, and operate the crane back and forth a few times, being careful not to run the
crane off the tracks. The loose sections of track will float and set the track to the exact crane span.
c ) After the operating span is determined, attach all the other sections of track to the floor making sure the track is
straight, level, parallel, and at the same elevation as the first track. The end stops should be set square with a 3-4-5
right triangle. The sides and the hypotenuse can be multiplied by any convenient number, such as three, used in the
example.
d ) Set one end stop at point A and measure along the runway track nine feet from point A to point B. With point B
as a center and fifteen feet as a radius, draw a circular arc on the floor. With point A as a center and 12 feet as a
radius, draw a circular arc on the floor intersecting the other arc at point C. A line running through points A and C
is perpendicular, or square, with the runway track.
e ) Extend this line to the other runway track to locate the end stop on that runway. Repeat the process at the other
end of the runway, or measure along each runway the same distance from these end stops for locating the stops at
the other end of the runways.
