Lifting Objects - Doosan DX140R Operation & Maintenance Manual

LIFTING OBJECTS

IMPORTANT
There may be local or government regulations, about the
use of excavators for the lifting of heavy loads. Always
contact your local and government agencies in regards to
these regulations.
When this machine is used in object handling applications, the
machine must be properly configured and operated properly.
Ensure the following safety working devices equipped and
operated.
• 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 94) straight below
the center line 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 most stable position is over the corner of the machine.
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
center line is increased.
