Chapter 4 Operation 31
The rotation system on the Tirehand is designed to allow the user to manipulate large tires. It is
a precision function that was not designed to apply high loads. However, the load holding valves
that are built into this system to help control the tire during handling will also prevent the body of
the Tirehand from rotating freely when loads are applied to a single Tirehand arm. When one arm
is used for bead breaking, these forces can translate into torques that attempt to rotate the body
of the Tirehand. The load holding valves will not allow this to occur. In this situation, the forces
that are created in the Tirehand rotation turntable are well in excess of what the gear teeth can
tolerate. Using one arm of the Tirehand for bead breaking will void the warranty of the Tirehand.
NEVER use one arm of the Tirehand
to break beads. Failure to comply may
result to severe equipment damage.
A bead breaker must be used to separate the tire from the rim. It is acceptable to use the
Tirehand for holding the sidewall and flange away from the bead while o-rings and locking rings
are being installed.
Tirehand Electrical Safety
Keep away from powerlines! If you must operate the Tirehand near powerlines:
1. For lines rated 350 kV or below, keep a minimum clearance of twenty feet (6.1 m) between
the lines and any part of the tirehand or load.
2. For lines rated over 350 kV, keep a minimum clearance between of fifty feet (15.25 m).
3. In transit, keep a minimum clearance of four (4) feet (1.22 m)
4. Use a signal person to observe the clearance and give timely warning for all operations
where it is difficult for the operator to maintain the desired clearance by visual means.
