STEP 2 - BOOM/MAST ASSEMBLY INSTALLATION
TIP: Upper and lower pivot bearing assemblies are identical.
2.1 Locate top pivot bearing assembly and bottom pivot bearing mast type jib cranes
assembly in the desired location (bolts by others).
Make sure the pivot bearing assemblies are in line and plumb
through pivot pin holes in the bearings (diagram 2A).
2.2 If using optional rotation stops, execute step A of the rotation
stops section on Rotation Stops before proceeding to next step.
2.3 Place the top and bottom pivot assemblies onto the top pivot pin and
bottom pivot pin of the mast. Be sure the thrust washer is between the
mast and bottom pivot bearing (diagram 2B). Take the entire mast
assembly with pivot bearing assemblies and raise them into position.
Bolt the top pivot assembly to the overhead support and the bottom
pivot assembly to the floor support. One-half inch (1/2”) clearance
should be allowed between top fitting and overhead support to ease
installation and for shimming if required.
2.4 For a MT400: Bolt boom to mast using bolts for the top of boom
Diagram 2A. Plumbing the pivot bearing
assemblies.
and bolts for mast connection plate using hardware provided
(diagram 2C).
For a MT450: Bolt boom to mast using hardware provided (diagram 2D). mast type jib cranes
2.5 Level boom to a point of 1/300 of span (in inches) above level. Shim, if
necessary, between mast and back of boom plate (shims by others).
Make sure that shim has full contact at connection and that there are
no voids. Torque nuts (chart 2A).
2.6 Tighten mounting bolts (grade 5 or better) to manufacturer’s specifications.
Bolt Dia. Torque
1/2" 50 ft.-lbs.
5/8" 95 ft.-lbs.
3/4" 175 ft.-lbs.
7/8" 300 ft.-lbs.
1" 450 ft.-lbs.

STEP 3 - ENDSTOP/TAGLINE INSTALLATION mast type jib cranes
3.1 Endstop
A) Bolt endstops to end of boom closest to mast (diagram 3A).
B) Roll hoist trolley (by others) into place.
C) Bolt remaining endstops into place at the front of boom
    (diagram 3A).
D) Torque nuts (refer to chart 2A, above, for proper torque
     rating).
3.2 Tagline Assembly
A) Bolt tagline bracket and an endstop to end of boom closest
     to mast (diagram 3B).
B) Roll hoist trolley (by others) into place.
C) Bolt remaining tagline bracket and endstop into place at the
     front of the boom (diagram 3B). Torque nuts (refer to chart
     2A, above, for proper torque rating).
D) Bolt eyebolt to the tagline brackets. Be sure the eyes of the
     eyebolts are oriented toward each other.
Diagram 3A. Endstop installation.

E) Run wire rope between eyebolts and clamp to form a loop
     at each end. Tighten eyebolts so wire rope is taught.
F) Add “S” hooks to wire rope and squeeze closed the top
     of the “S” hook.
G) Space “S” hooks evenly along wire rope and place round
     power cable/air hose through bottom loop of the “S” hooks.
H) Squeeze bottom of “S” hook to grip wire, or tape wire in
     place. Do not squeeze too tightly or damage may occur to
     power cable or air hose.

STEP 4 - OPTIONAL ACCESSORIES
4.1 Rotation Stops
A) Prior to mast installation: Locate rotating stop block. Weld
     stop block to under side of mast bottom plate using E70xx
     electrodes, per AWS D1.1 specifications (diagram 4A).
B) Swing boom to the farthest position of use in one direction.
C) Place stationary stop block on lower pivot assembly against
     the rotating stop block.
mast type jib cranes
D) Weld stationary stop block to lower pivot assembly using
     E70xx electrodes, per AWS D1.1 specifications (diagram 4B).
E) Repeat Steps A-D for opposite direction.
F) Touch up with paint provided.
4.2 Bottom Entry Collector
A) Connect wires through the pivot pin to the collector wires
     (diagram 4C).
B) Place connector over the top of the pivot pin making sure the
     connected wires are pushed down inside the pivot pin.
C) Lock the connector in place by tightening the set screws at the
     base of the collector.
D) Connect the collector to the stabilizer bolt mounted in the mast
     assembly.
E) Add appropriate size hole in the collector cover to allow
     installation of hoist power cable to collector.
F) Attach collector cover with mounting hardware provided.
