Hydraulic Vertical Capstan

Application

A hydraulic vertical capstan is a type of mechanical device used for pulling or hoisting heavy objects, typically on boats and ships. It consists of a vertical drum, often made of steel, that is powered by a hydraulic motor. The drum is typically designed with grooves or teeth on its outer surface, which helps to grip and hold onto ropes or cables that are wrapped around it. To operate a hydraulic vertical capstan, a hydraulic pump is used to generate high-pressure fluid that powers the hydraulic motor. When the motor is activated, it turns the drum, which in turn pulls or lifts the object being moved.

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.
			316L 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.

How to install Hydraulic Vertical Capstan 

The installation of a hydraulic vertical capstan requires careful planning and execution to ensure that the equipment is installed safely and effectively. Here are some general steps that may be involved in installing a hydraulic vertical capstan:

1) Determine the mounting location: The first step in installing a hydraulic vertical capstan is to determine the mounting location. The capstan should be mounted in a location that provides adequate clearance and access for the equipment to function properly. The mounting location should also be strong enough to support the weight and forces associated with the capstan.

2) Prepare the mounting surface: The mounting surface should be cleaned and prepared to ensure that the capstan can be securely attached. If necessary, reinforcement plates or additional support structures may need to be installed.

3) Install the capstan: The capstan can be attached to the mounting surface using bolts or other fasteners. The capstan should be aligned properly to ensure that the rope or cable can be properly loaded onto the drum.

4) Connect the hydraulic system: The hydraulic system should be connected to the capstan using high-pressure hoses and fittings. The system should be tested for leaks and proper operation before use.

5) Install the control system: The control system should be installed and connected to the capstan, allowing the operator to control the speed and direction of the capstan.
6) Test the capstan: The capstan should be tested to ensure that it is functioning properly and safely. This may involve testing the capstan under load and verifying that all safety features are functioning correctly.

7) Provide training: Anyone who will be operating the hydraulic vertical capstan should receive proper training on its operation and safety procedures.
Overall, the installation of a hydraulic vertical capstan should be performed by qualified professionals with experience in marine equipment installation. Proper planning and execution can help to ensure that the capstan is installed safely and functions effectively for its intended purpose.
