Tadano GT-550E-2, Operation And Maintenance Manual

Page: 11 / 100

Lift Single Loads Only
Do not lift two or more loads simultaneously even if
their total mass is within the specified rated lifting
capacity; otherwise, the loads may lose balance. It
is usually not possible to maintain complete atten-
tion to multiple loads.
Operate According to Signals
If signals are not obeyed or if signals are improperly
made, accidents can occur.
Follow instructions of the signal person. An emer-
gency shut down signal must be acknowledged
whoever gives it.
Operate the Crane from the Operator’s
Cab Only
Controlling the machine from outside the cab,
through the cab window, is strictly forbidden and
extremely dangerous.
Conduct a Safety Check within the Load
Radius of the Crane before Starting
Operation
Any person located close to the crane may become
caught between machine components or between
the counterweight and a fixed obstacle. Before
starting any swing motion, make sure that there is
no one nearby. Sound the horn to warn all immedi-
ate personnel of crane startup.
During crane operations, fence off or barricade the
work area to prevent unauthorized persons from ap-
proaching the machine.
Be Extremely Careful When Raising the
Load Clear of the Ground
Stop lifting the load once the rigging is fully taut,
check that the load is suspended at a point just
above its center of gravity, and that the load is not
stuck to the ground or interfering with a nearby
body or structure.
Lift the load vertically. When the load clears the
ground, stop lifting and suppress any swaying; then
check that the rigging is secure, the load is in a sta-
ble position, and the crane is not overloaded.
Then, recommence the lift again.
Do Not Lift the Load Clear of the Ground
by Raising or Extending the Boom
Raise a load clear of the ground by vertical hoisting
only.
Raising or extending the boom to lift a load clear of
the ground will cause the load to sway, posing a
hazard.
If the boom is elevated to raise a load clear of the
ground, the crane will not be automatically stopped
even in case of an overload. An overloaded machine
can overturn or be damaged.
