Note:1.The load listed in this load chart is under double parts of line. When working under single parts of line,the lifting capacity of same boom combination and working radius is same as
that of double parts of line. But it cannot exceed 13.5t.
2. When using 18m fly jib and the angle is 10°, 80t hook or more than 1.2 t hook should be used by jib to prevent the crane tipping.

4.1.1 Hook over-hoist prevention device
Hook/boom over-hoist prevention device is a safety device, which will prevent the crane from
damages and overturning. So it is necessary to ensure the safety device in normal operation in
order to perform the crane operation more safely.
Under normal working condition, the hook hangs down naturally. The micro switch is normally on
power.
Hook over-hoist prevention device
When the hook (main/ aux. hook) is lifted up to a certain height and touches the block which in
turns activates the micro switch (which will be in open position) by the spring tension and it will
cut off the power supply to the control circuit which controls the hook hoist up action and light up
the warning lamp and activate the buzzer. Only hook lowering action is allowed and the hoisting
action is stopped automatically to prevent overhoist from happening. If main and aux. hooks work
simultaneously, the two hooks can not do lifting action, for two micro switches are in series.

Chapter 7 Wire Rope
Most actions of this crane are done by wire rope. The quality and disposal of wire rope has great
influence on the crane, so it is important to correctly use the ropes which
are appointed by the manufacturer of the crane.
7.1 Unwinding of the wire rope
Warning
z
Do not touch wire rope directly with bare hands. If wires protrude,
you could be injured. Working gloves are recommended.
z
Keep hands and clothing away from the rotating drum and running
wire rope.
z
Failure to observe this precaution may result in serious injury or loss
of life.
When unwinding the wire rope to install the crane, please follow the below correct method
Right
Wrong
The wrong unwinding method of wire rope will disturb the construction of the rope and cause
looseness, kinking or twist which may seriously affect the service life of wire rope.

7.2 Storage of wire rope
z
Please keep the wire rope in dry room, If must keep outside, please cover it with waterproof

z
Wire rope should be supported with wooden blocks. The height above the ground is
200-300mm.
7.3 Winding Wire Rope onto the Drum
See following pictures
Correct
Wrong
Correct winding method of wire rope
Cautions for Rope winding on drum：
a．Select wire rope length appropriate to the working conditions to prevent wire rope in the
upper layer from thrusting into the clearance between the ropes in the lower layer when a load
is lifted.
b．When rewinding wire rope in the first layer on the drum, continuously apply a line pull.
c．When the machine was shipped from the factory, wire rope is installed on the drum without
applying a line pull tension. Therefore, if a large load is lifted, wire rope in the upper layer may
be thrust into the clearance between the ropes in the lower layer, possibly resulting in wire rope
lay looseness, irregular winding, and/or premature strand wire breakage.
d．Before using wire rope on the drum, be sure to pay out wire rope to its full length. Then,
7-2 / 10
QUY250 Operation Manual
Chapter 7
Wire Rope
rewind wire rope in the first layer on drum while applying a line pull tension corresponding to the
type of the work in which the machine will be engaged.
Caution
Wind the pull of first layer wire rope correctly.
When a 6-strand wire rope is used, proper line pull tension for winding wire rope corresponds to
10 to 15% of the load to be lifted per a reeved line. When self-rotation-resistant rope is used,
proper line pull tension for winding wire rope shall correspond to 15 to 20% of the load to be
lifted per a reeved line.
z
Comply with the following procedures when winding the rope on the drum
1. Attach the rope to the drum. Do not extend the end of the rope beyond outer drum surface.
2. When reeling wire rope on the drum, use care to guide the rope in line with each other from
one end of the drum.
3. When the first layer is finished; wire rope should be hammered or pushed into place
with hammer or pry bar to ensure an even winding surface.
4. Keep the gap as smaller as possible between the drum and the first coil of wire rope when
winding continuously.
5. Always keeps sufficient tension when winding.
6. Winding in disorder should be absolutely avoided, which is the main reason to cause the
premature break.
7. As a usual practice that rope rewinding is necessary after a long period of use, or it will run in
disorder occasionally.
8. After installing wire rope in the socket, use rope clip to fix rope end.
9．As a usual practice that the new wire rope needs to test with the moderate rated load after
the installation of new wire rope.
10．Apply the grease to wire rope properly.
7.4 Correction of rope entanglement
According to wire rope inherent construction, when a load is applied to wire rope, the wire rope
7-3 / 10
QUY250 Operation Manual
Chapter 7
Wire Rope
rotates in the direction as the lay is unwound. This property is called “self-rotation”. In high lift
operation or the hook is suspended with 2 to 3 falls, wire ropes may tangle each other due to
the self-rotation property, possibly causing the lifted load to spin so that a safety hazard is
created and/or work efficiency may be reduced. Although self-rotation-resistant rope which can
reduce rope self-rotation property is available, the occurrence of self-rotation can not
completely be prevented.
The method of correcting rope entanglement
Refer to the drawing of the direction of entanglement to judge the entanglement direction of wire
rope.
Hook turns clockwise
Hook turns counterclockwise
Note：
The direction of entanglement（when wire rope is Z lay），wire rope without load is parallel;
wire rope with load is often entangled as the above illustrated.
z
After completely releasing rope tension, detach wire rope socket and rotate the rope end
(rope socket) by hands so that rope entanglement is corrected toward the drum side in
sequence by repeating to hoist and lower the hook.
Rotation direction of rope socket:
z
Rotate the rope socket in the same direction as the hook is rotated by rope entanglement.
z
To S-direction entanglement, rotate clockwise.
z
To Z-direction entanglement, rotate counterclockwise.
Cautions:
①Number of rotations to correct rope entanglement
② Number of rotations to correct rope entanglement=Number of reeved line×Number of
7-4 / 10
QUY250 Operation Manual
Chapter 7
Wire Rope
entanglement (Number of hook turns)
Count required number to slowly rotate the hook until ropes become parallel after the ropes
cease entangling.
③If the rope is rotated more than 5 turns at one time, the rope ray will become loose. Limit the
number of rope rotations up to 4 to 5 turns at a time. Repeat rotations as required.
④The cause of entanglement depends on the time when entanglement occurs.
⑤ If entanglement occurs during test operation soon after the rope is installed, correct
entanglement according to the method mentioned above.
z
In case entanglement occurs after the machine has been operated for a certain period of
time, the following items may be a possible cause of entanglement.
z
After the rope was excessively drawn along the sheave grooves, length of rope lay length
become uneven.
z
Too small sheave diameter, worn sheave groove and too large fleet angle between the
sheave center and wire rope center.
Caution
z
Take care to the rotation of the
rope socket when dismantling
the rope socket.
Twist of boom derricking drum wire rope：
The boom derricking drum rope may occasionally wave when the rope lay is unwound. If this
occurs; remove the rope socket to restore the rope lay. Also, check that the sheaves can rotate
smoothly at the same time.
7.5 Replacement of wire rope
The service life of wire rope is much more different due to separate working conditions. It is
therefore very important that wire rope be inspected at regular intervals. Using defective rope is
not allowed. All ropes including the hoisting ropes and pendant ropes must be checked at
regular intervals. Severe accident will occur without checking wire ropes strictly.
1．Replacement intervals of wire ropes are evaluated with their broken wires, wear and
corrosive conditions.
More than 10% number of strands (except filler
7-5 / 10
QUY250 Operation Manual
Chapter 7
Wire Rope
type) within one length of lay broken.
2. The diameter of the wire rope reduces due to the damage of the rope core. When the actual
diameter is less than 3% (resistant rope) or 10% (other ropes) of the nominal diameter, the wire
rope should be replaced as soon as possible.
Note：The actual diameter of new wire rope may be more than the nominal diameter of
wire rope. The allowed tear and wear will increase.
3. Reduction in diameter exceeded more than 7% of the nominal diameter.
4．Kinked wire rope.
5. Remarkable deformation or corrosion is recognized.
6. The wire rope waves and is heavily deformed.
7．The inner parts of wire rope has been protuberant.
8．Extremely stretched rope by receiving excessive loads or from coming off sheaves.
9．Arced rope by contact with electric current.
10．In case the rope was exposed to electric or gas welding sparks or high temperature.
In addition, such as the pendant ropes are subjected to shock and heavy loads, care must be
paid for failure due to fatigue of materials. The replacement of a rope can be considered
according to above conditions but inside conditions can not be estimated due to different
working conditions. All in all, ropes should be replaced every 2000 servicing hours even if the
above descriptions are followed.
Ropes must be discarded immediately if any one or any combination of the following defects is
found：
① Some strands close to the balanced sheave have contusion.（Sometimes the breaking wire
is choked by the sheaves.），See fig. 1
