Lifting Objects
When this machine is used in object handling applications, the
machine must be properly configured and operated. Ensure the
following safety working devices are equipped and operational.
•
Lifting eye for load hooking.
•
Hose burst protection on both boom and arm.
•
Overload warning devices.
To prevent injury, do not exceed the rated load capacity of the
machine. If the machine is not on level ground, load capacities
will vary.
Short slings will prevent excessive load swing.
Use the lifting eye on the bucket that is provided to lift objects.
Always try to maintain the lifting eye (Figure 115) straight below
the centerline of the arm and bucket pin. In this manner the
weight of the load is being primarily held only by the pin, and not
by the bucket cylinder, link, and link pins.
When a lifting eye is used, the sling/lifting device must be
fastened to the eye in a manner that will not allow it to come
loose.
The highest lift capacity of the machine is over the front and rear
of the machine.
If the machine is equipped with a dozer, the highest lift capacity
is over the rear (Figure 115).
For best stability, carry a load as close to the ground and
machine as possible.
Lift capacity decreases as the distance from the machine swing
centerline is increased.
NOTICE
There may be local or government laws or regulations
governing the use of excavators for the lifting of heavy
loads. Always contact local and government agencies and
follow all applicable laws and regulations.
