EXCAVATOR RATED LIFT
CAPACITY TABLES
AVOID DEATH OR SERIOUS INJURY
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.
AVOID DEATH OR SERIOUS INJURY
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
equipment failure and/or structural collapse of the machine.
To operate safely the excavator must 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 respond to changes in those 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.
