OPERATION
- 05 -
A. Cautions before operation
4. Duty ratings refer to the type of use the equipment is subject
to. Consider the following when determining duty rating.
• Environment: harsh environments include hot, cold, dirty, wet
corrosive, or explosive surroundings. Protect the equipment
from harsh environments when possible.
• Maintenance: poor maintenance, meaning poor cleaning,
lubrication, or inspection, leads to poor operation and
possible damage of the equipment. Minimize poor
maintenance by carefully following the instructions
contained in this manual.
• Loading: severe loading includes shock loading and lifting
loads that exceed the load rating of the equipment. Avoid
shock loads, and do not exceed the load rating of the
equipment.
• Frequency of operation: frequent or lengthy operations
increase wear and shorten the life span of gears, bearings,
pulley, and other components.
1. The force required to lift the load must not exceed the load
rating of the crane. Consider the total force required to lift the
load, not the weight of the load.
2. This equipment can not develop forces that will exceed the
load rating.
3. Performance ratings of the equipment are affected by the
position of the boom. See the performance characteristics
Table 4, Table 5, Table 6.
• Load rating represents the maximum force that can be placed
on new equipment. Load ratings are assigned values for
specific boom positions and wire rope lengths. Crane load
ratings decrease as you extend the boom.
• Lift varies with the position of the boom and the length of the
wire rope.
• Reach varies with the position of the boom.
B. Prepare operation
When adjusting boom length, set the boom angle just above
horrizontal and hold the telescopic boom securely so it does
not slide abruptly in or out of the upper bracket weldment
causing damage or injury.
When adjusting the boom angle, raise the rotation lever(#6-
E1000 & E2000) with one hand and operate the ratchet jack
(#5) with the other to avoid jamming or injury.
1. Be conscious that you can perform the entire operation without
hazard.
2. Inspect all components and parts of the equipment.
3. The load must be clear of other objects and free to move. Make
sure the load will not tip, spin, roll away, or in any way move
uncontrollably.
4. Konw your load and make sure you do not exceed the load rating
of the crane and its any components.
5. Position the boom so the load hook is centered over the load
avoid sidepulls which could damage the crane or cused the load
to tip. Refer to fig.1 on page 1.
6. Adjust the boom length by moving the telescopic boom weldment
in or out. The load rating decrease as you move the boom out.
Refer to performace characteristics table on page 9-11.
7. Adjust boom angle by operating the ratchet jack(for E1000 and
E2000) to raise the boom or lower the boom.
C. Attaching the load
1. Clear objects from the path of the load so you can move it freely
and obseve it at all times during the operation.
2. Make sure the wire rope is not twisted. A twised wire rope could
cuase the load to spin when it is raised off the ground.
3. Seat the wire rope or sling in the saddle of the hook with hook
safety latch completely closed.
4. Centre the load on the hook so it will remain balanced and not
tip or rotate to one side.
WARNING
Do not wrap the wire rope round the load. This will damage the
wire rope and could cause the load to slip out. Use a sling or
other approved lifting device.
D. Moving the load
1. Move the load slowly and smoothly at the beginning to make sure
the load is balanced and securely attached before continuing.
2. Operate the winch to raise or lower the load. Refer to the winch
operation manual provided.
3. Observe the wire rope as it winds onto the drum. If it becomes
loose, uneven, or overlapped, stop the operation and rewind the
wire rope before continuing. Continued operation with overlapped
or uneven wire rope can damage the wire rope and shorten its life.
4. Operate the ratchet jack(for E1000 & E2000), if necessary, to
adjust the angle of the boom to keep the pulley centered over the
load.
5. Rotate the boom to move the load side to side.
1). Rotate the boom slowly and smoothly to avoid swinging the
load or causing shock loads. Do not jam the boom against
other objects.
2). Use the handle to rotate the boom. Do not push or pull the
load or the wire rope to rotate the boom.
