Round cord cable, and widely used on board halyard, sports facilities, children's entertainment, etc. The surface is smooth, the use of safe and favored by the majority of customers and accept the customization of various specification, inventory adequate, lightning shipments.
The use of the heaving head knot：
In the past, crews often used scrap metal or gravel, or heavy weights such as hook rings, to increase the end of the line to allow it to go further. This operation mode has been banned, because it will increase worker, shore workers, tug with cable or the mooring boat crew members in the mooring operation was struck by the object, or the ship mooring personnel when heaving line is thrown back to hit and cause the risk of serious personal injury.
1. The preparation of the heaving line：
Place the eye ring at the end of the cable to the left wrist, and turn it clockwise into a circle with a diameter of about 30 cm. The coil should be prevented from twisting into a twist, otherwise, the rope will be tied and the impact will be thrown. Practice shows that the smaller the circle is, the smoother the loop is when the left hand can hold. After the circle is closed, the left hand holds the loop of the rope naturally bent and is placed in the waist, and the right hand grabs the cable and lifts the heaving line about 80 cm from the distance. Pay attention to the length of the rope between your hands.
2. The throwing point of the heaving line:
When you are ready to do your work, stand on the left side of your body, with your feet wide open and your body centered on your right leg. Right hand filed a heaving line head slightly to do back and forth, then drive the heaving line head from bottom up, by the former backward in a 45 ° Angle at the upper body rotation. The rotation speed should not be too fast, otherwise, the throwing direction is difficult to control and is not safe. The key to throwing distance is the explosive power of the shot.
After the rotation 2 to 3 turns, when the heaving line is turned to the right side of the body, use the continuous movement of the waist, chest and swing arm, while the center of gravity shifts to the left, leaving the heaving line at a 45-degree Angle.
Attention should be paid to the "starting point" as far as possible, and the quick pull of the arm to improve the acceleration of the "flying" of the heaving line. It is crucial to grasp the "shot point", too early or too late will cause the heaving line to fly out of the target. In a moment, the palm of the palm should be directed towards the target and the fingers are naturally extended to prevent the rope from being pulled.
When shooting, you should shout "come" along with the heaving line and fly out quickly. On the one hand, it can serve as a boost for a weightlifter. On the other hand, it can warn the other party to prepare for the emergency and timely response.
