Hydraulic Vertical Capstan

Application

The hydraulic vertical capstan is an equipment for mooring or anchoring various ships when the ship arrives at the port or dock. It usually consists of a mooring head of a steel wire rope driven by a hydraulic power unit (HPU). The HPU device can be driven by a diesel or electric motor. The hydraulic vertical capstans  can realize the stepless control of the capstan head by hydraulic or frequency driven capstans.

The type of material of the mooring line affects the size of the capstan head, the type of cable and bending radius, the occupied deck space, and the like. It is recommended to select the appropriate mooring line material for strength, flexibility, durability and running performance. Hydraulic vertical capstan mainly consists of hydraulic motor, gearbox, capstan head, brake and so on.

Configuration options

Part Name	Type/Material	Advantages/Disadvantages
Capstan Head	ZG270-500	Medium carbon cast steel has certain toughness and plasticity, high strength and hardness, good machinability, acceptable weldability, and poor casting performance than low carbon steel. Casting defects cannot be avoided.
	ZG270-500 Precision Casting	High cost and no defects
	ZG310-570	Very high strength, excellent toughness and plasticity, low cost.
	Q345-B	The high strength of welding capstan head.
	Stainless Steel	Cold-rolled products have an excellent gloss and beautiful appearance; good processing performance; excellent welding performance; excellent pitting corrosion resistance, incredibly high-temperature strength, and excellent intergranular corrosion resistance.
Gear Reducer	Domestic second-tier brands	Poor quality and short service life.
	Domestic first-line brand	Cost-effective and long service life.
	*Homemade (recommended)	Good quality, cost-effective
Hydraulic Motor Type	DONGFANG and XINHONG brand	Good quality, cost-effective, long service life. With brake, high safety.
	Other brands	High power consumption, relatively poor quality.

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.
