Hydraulic Stainless Steel Capstan

Application

A hydraulic stainless steel capstan is a type of equipment used in marine and industrial applications for mooring, anchoring, and towing operations. It is designed to provide a strong, reliable, and efficient means of handling heavy loads and equipment in harsh marine environments. Hydraulic stainless steel capstans are commonly used in commercial shipping, offshore drilling, and marine construction operations. They can be used to pull heavy anchors, moor ships and boats, move heavy equipment, and tow vessels in and out of harbors and docks. They are also used in industrial applications, such as steel mills and mines, to move heavy loads and materials. Overall, hydraulic stainless steel capstans are important pieces of equipment for many different industries and applications, providing a reliable and efficient means of handling heavy loads in challenging environments.

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.
	316 L 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.
Gypsy Stripper	Q345D	It has good comprehensive mechanical properties, good weldability, cold and hot workability and corrosion resistance, and has good low temperature toughness (high strength, good welding performance).
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.

Due to the fierce market competition, the phenomenon of low quality of other capstan suppliers is frequent. What is the difference between us and other low-quality suppliers?

The specific differences are as follows:

Part name	Other low quality suppliers	Result	Our factory	Consequence
Capstan head	ZG270-500	Casting defects cannot be avoided	Q345-B	High welding strength and slow wear.
			ZG310-570	Very high strength, excellent toughness and plasticity, low cost.
			Stainless steel	Cold-rolled products have excellent gloss and beautiful appearance; excellent processing performance; excellent welding performance, corrosion resistance; slow wear and high cost performance.
Gypsy Stripper	Cast iron	Cast iron has good casting performance, but when the carbon content of cast iron is relatively high, its performance is relatively brittle, and its tensile performance is relatively poor; it is easy to corrode and wear quickly, which is not conducive to load.	Q345D	The Q345D steel plate is preheated before welding to prevent the occurrence of cold cracks. And Q345D has good cold and hot working properties and corrosion resistance, and has good low temperature toughness. Conducive to load, slow wear.
Gear reducer	Domestic second-tier brands	Poor quality and short service life.	Homemade or domestic first-line brands	Good quality and cost-effective.
Hydraulic Motor Type	Other brands	High power consumption, relatively poor quality.	DONGFANG or XINGHONG brand	Cost-effective, good quality. With brake, high safety.

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.
