Excavator Rated Lift Capacity Tables - Doosan DX27Z Operation And Maintenance Manual

EXCAVATOR RATED LIFT
CAPACITY TABLES
Let everybody be away from the boom cylinder. While
lifting operation, boom, arm, bucket hoses might burst
and then high-pressure oil will be ejected at high-speed.
If that failure mode takes place, handling weight or front
structure might fall by its gravity to the ground to cause
fatal injury to the person.
When changing the hoses record the part numbers of
the hoses to factory log book.
Do the service job under the company's serviceman.
All rated lift capacities are based on the machine and
the load both remaining level at all times. DO NOT
EXCEED THE RATED LIFT CAPACITY. Lifting loads
greater than those shown in the rated capacity tables
can cause catastrophic
structural collapse of the machine.
To operate safely the excavator should be on a firm, level
and uniformly supporting surface. The operator is expected
to make due allowance for all specific work site and lift
related conditions, and
conditions that could pose a hazard. The following could all
cause hazardous conditions and accidents or injuries:
• Soft or uneven ground.
• Unlevel terrain.
• Side loads.
• Modifications or poor maintenance of the excavator.
• Failure to lift squarely over the end or over the
side of the machine.
When a load is in the air, the operator must remain alert.
• Avoid side loads that may be caused by uneven
slings, traveling with the load or swinging too quickly.
• The load can become unbalanced if the hook line
is twisted and starts to rotate. If the surface area
of the load is large enough, wind gusts can
create side loads.
• Keep the bucket hook point directly over the load. Tag
lines on opposite sides of the load can help maintain
greater stability against side loads and wind gusts.
