注意:

1、合成绳索仅限用于非工业的越野自救应用。
2、尖锐物体接触及磨损会显著缩短合成绳索的寿命。每次使用前都需要检查合成绳索是否安装牢固及完好无损。

安装:

如需自行安装合成绳索,严格检查绞车滚筒和导缆器是否有任何损坏,缺口或毛刺,以免损坏合成绳索。

步骤1

将合成绳索穿过导缆器,从滚筒下方绕过并穿过滚筒上的绳索固定孔。

步骤2

从滚筒上的绳索固定孔拉出合成绳索,以足够滚筒的长度,并使用胶带等将这段绳索固定在滚筒上。

步骤3

保持一定的拉力,将绳索缠绕在滚筒上。绳索必须保持至少8圈始终保持在鼓筒上。

合成绳索的日常检查

新的合成绳索是光滑完整的(图1)。当合成绳索第一次使用时,绳子的外部细丝会变粗糙,给绳子带来一点“模糊”的外观(图2)。外部细丝的这种状况形成粗糙的绳索表面,实际上有助于保护下面的纤维。当大约25%的可见外部纤维表现出磨损时,必须更换绳索(图3)。

检查内部和外部纤维。通过长度方向挤压绳索打开绳索的各股(图5),寻找其中的粉末纤维和磨损——这是绳索内部磨损的标志,从而确定绳索的总体磨损程度。

绳子中有光泽区域(图4)可能是由于两种不同的条件造成的。最常见形式是由挤压引起的,这种挤压可能在将绳索缠绕在绞盘鼓上或通过滑轮组上时发生。将绳索纵向挤压(图5)通常会使绳索更加柔韧并获得性能恢复。如果光泽区域保持硬化,这可能是热损伤的迹象,必须更换绳索。

延长合成绳索使用寿命的提示:

1)尽量减少绳索磨损。当绳索与岩石或其他物体接触时,使用可移动的磨损套管,并根据需要上下滑动套管。
2)保持绳子清洁。污物和碎屑进入绳索将导致绳索的磨损。
3)避免死结。绳索的死结使得其在负载下的强度降低,并可能导致绳索损坏。
4)对于所有负载,使用一个滑轮组,可以获得超过1/2的额定绞盘拉力。

原文INSTALLATION - SAFETY PRECAUTIONS由Superwinch提供。

! CAUTION This product to be used for non-industrial self-recovery in off-road applications only. This product not to be used for any other purpose. It is the user's sole responsibility to follow safe use guidelines to prolong the life of the winch rope. See winch owner's manual for furtherinformation.

! DANGER Sharp edges and abrasion will significantly shorten rope life. Inspect entire length of rope and protective sleeve before each use. Any rope that exhibits cut strands, fused or melted fibers, inconsistent stiffness over the length of the rope, chemical contamination, flat areas or lumps that are not eliminated by flexing the rope, or is otherwise visibly damaged must be replaced immediately. Failure to do so can result in rope failure and personal injury.

Synthetic Winch Rope Installation:

Your synthetic winch rope comes fully assembled and ready for installation. Follow the simple steps below to secure the synthetic rope (line) to your winch. Please read through the entire installation process before beginning.

Note: When installing synthetic winch rope on a winch that has previously run wire rope, it is required that both the winch drum and fairlead are closely inspected for any damage, nicks, or burrs that may damage the synthetic rope.

Using sandpaper, a scuffing pad, or equivalent, make sure drum and fairlead surfaces are free of any damage. It is your responsibility to make sure the winch drum, fairlead and other items particular to your installation are free of damage. We recommend a new aluminum hawse fairlead be used with your new synthetic rope.

Step (1)

Install winch and fairlead, if this is a new winch installation. (See your winch owner's manual.) Pass end of line through fairlead, under drum, and through hole in drum.

Step (2)

Pull approximately 8" of line through hole (enough line so it reaches opposite end of drum). Position inserted line lengthwise down the drum as shown. Using duct tape or similar, secure end of line to drum, taping around drum.

Setscrew is not used in this installation. You are now ready to wind on the line. (Be sure that line is wound on from underneath drum. Line should come off drum on bottom.)

Step (3)

Using moderate tension, such as winching the rolling vehicle across a level parking lot, wind the line onto the drum. A minimum of 8 wraps of the first layer of synthetic rope must remain on the drum at all times during winching. This is to ensure that the rope remains
securely fastened to the drum.

Synthetic Winch Rope Inspection:

When rope is new, it has a smooth finish (fig. 1). When the rope is first used, the outer filaments of the rope will roughen and give the rope a slightly 'fuzzy' appearance (fig. 2). This condition of the outer filaments creates a rougher rope surface and actually helps to protect the fibers underneath. Rope must be replaced when approximately 25% of the visible outer fibers exhibit abrasion (fig. 3).

Examine both inner and outer fibers. Open the strands of the rope by compressing the rope length-wise (fig. 4) and look for powdered fiber and abrasion - this is a sign of internal wear of the rope. Estimate internal fiber loss to include in your determination of overall abrasion fiber loss of the rope.

Glossy or glazed areas in the rope (fig. 4) can be the result of 2 different conditions. The most common form of glossing or glazing is caused by compression, which can be occur when the rope is wound on the winch drum, or through a pulley block. Compressing the rope length-wise (fig. 5) will generally make the rope more pliable and begin to resemble normal rope. If the glazed section remains hardened, this can be a sign of heat damage, and the rope must be replaced.

Tips for prolonging the life of your synthetic rope:

It is your responsibility to exercise proper care to prolong the life of your synthetic winch rope.

1) Minimize rope abrasion. Use the movable abrasion sleeve whenever the rope comes in contact with rocks or other objects. Slide the sleeve up and down the rope as required. Abrasion will reduce rope life.
2) Keep the rope clean. Allowing dirt and debris to enter the rope will lead to abrasion of the rope.
3) Avoid sharp bends. A sharp bend in the rope decreases its strength substantially under load and may cause rope damage or failure.
4) Use a pulley block for all loads over 1/2 of rated winch capacity.
