Electric Horizontal Capstan

Application

The electric horizontal capstan is the simple device and it is easy to install and operate. The capstan capacity of electric horizontal capstan rope results from the nominal rope pull and the related rope speed. The capstan head is driven by an electric motor and the torque transmission gear is placed in the capstan head.  It is typically mounted horizontally on the deck of the vessel and is used to control the movement of lines or cables that are used to secure the vessel to a dock, anchor or other fixed point.

The protection class of electric horizontal capstan is usually IP56 because of its special working occasions. The capstan consists of a drum, which is attached to the electric motor and rotates as the motor turns. The line or cable is wound around the drum and is held in place by a series of jaws or clamps. The motor can be controlled using a switch or remote control, which allows the operator to control the speed and direction of the capstan.

Capstan precautions

1. First of all, the reasonable method in the dragging process is to fix the traction point, fix the body, and skillfully use tools such as tree-hugging belts and ground spears to ensure the reliability of the clutch switch.

2. Ensure that the towing vehicle and the towed vehicle are in a straight line. The angled traction will firstly offset the traction force, and secondly, the steel cable of the winch will be wrapped around one end. If the angle cannot be adjusted, the directional pulley can be used.

3. When pulling objects, if you need to loosen the steel cable, you should use the loosening button with caution, which will easily cause the steel cable to be knotted and entangled on the reel. You can use the clutch to stretch the cable as straight as possible.

4. When dragging heavy objects or vehicles that are difficult to drag, a pulley block can be used to form a loop to increase the traction.

5. A spare battery is also required. The winch can quickly run out of battery power. Double batteries are necessary, and the second battery can be made larger.

6. Wear gloves when operating the winch cable, and place rubber pads and other items on the cable to prevent destructive rebound after the winch cable breaks.

7. When using the winch to pull heavy objects or vehicles, always pay attention to the battery voltage. If the battery voltage is too low, stop the operation immediately, and increase the battery voltage by increasing the engine speed to force the generator to charge. Because the power of the winch motor is rated, the lower the voltage, the greater the current that breaks down the battery and the control relay, and the forced use of low voltage is easy and faster to reduce the life of the battery and the relay in the control box. In the case of low voltage, the rope retraction speed will also be slower.

8. The winch should be rigidly connected to the most solid and reliable place of the car body to avoid separation from the car body or other dangers during towing.

9. If the time is tight and the neatness of the rope cannot be guaranteed, it is also necessary to release the rope fence when conditions permit and rewind the rope fence neatly on the reel. Avoid long and messy winding of the rope fence.
