Electric Combined Winch

Electric Combined Winch

Application

Electric combined winch is a combination of anchor windlass and winch. It is an ideal choice to perform both anchoring and mooring functions in various types of vessels. The winch can be electrically driven depending on the existing infrastructure. An electric combined winch is a type of machinery that combines both a winch and a hoist into a single unit. It is powered by an electric motor and is commonly used in industrial and construction settings for lifting and pulling heavy loads. Electric combined winches come in a range of sizes and capacities, from small portable units used in light-duty applications to large, heavy-duty models used in construction, mining, and offshore operations. They can be configured with a variety of accessories, such as wire ropes, chains, and slings, to suit different types of loads and applications.

Configuration options

Part Name	Type/Material	Advantages/Disadvantages
Drum	Q235-A	It has good toughness and plasticity, has a certain elongation, and has good weld-ability and hot work-ability. Q235A is generally used in the hot-rolled state. CCS no longer needed Q235A.
	Q235-B	Has a certain elongation, strength, good toughness and cast-ability, easy to stamp and welding. Suitable for products with small loads.
	Q345-B	Good comprehensive performance, good low temperature performance, good cold stamping performance, good welding performance and machinability. (High strength, good welding performance).
Warping 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	Cost-effective
	Q345-B	The high strength of welding warping head.
Gypsy Wheel	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).
Reduction Gearbox	Domestic second-tier brands	Poor quality and short service life.
	Domestic first-line brand	Cost-effective and long service life.
	*Homemade (recommended)	Good quality, high cost.
Cluth	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.
	Q345-B	Good quality, high cost.
	45	Good cutting performance, high hardness after quenching, good toughness and certain wear resistance after quenching and tempering. Good quality, high cost.
Brake	Q345-B	CCS regulations
Electric Motor Type	HENGLI and LANHAI brand	Good quality, cost-effective, long service life. Self-contained brake, high safety.
	ABB/WEG/Siemens	Good quality, high cost, long delivery time.
	Other brands	High power consumption, relatively poor quality.
Pedestal	Q235-B	Suitable for products with small loads.
	Q345-B	High strength and good welding performance.

Due to the fierce market competition, the phenomenon of low quality of other winch 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
Drum	To reduce costs, reduce the thickness of the drum.	The thickness of the drum is too thin, which is not conducive to the load and wears quickly.	Produced in strict accordance with product production standards, with moderate thickness.	The thickness is moderate, which is good for loading, wears slowly, and does not cause the product to be too heavy to increase the transportation cost.
Warping head	ZG270-500	Casting defects cannot be avoided	Q345-B	High welding strength and slow wear.
Gypsy Wheel	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.
Reduction Gearbox	Domestic second-tier brands	Poor quality and short service life.	Homemade or domestic first-line brands	Good quality and cost-effective.
Cluth	ZG270-500	Casting defects cannot be avoided.	Q345-B	Good quality and cost-effective.
Brake	Q345-B	Good quality and cost-effective.	Q345-B	Good quality and cost-effective.
Electric Motor Type	Other brands	High power consumption, relatively poor quality.	HENGLI or LANHAI brand	Cost-effective, good quality. Self-contained brake, high safety.
Pedestal	Q235-B	Low strength, suitable for products with small overload; Used for heavy loads winches, wear out quickly and break easily.	Q345-B	Higher strength, slower wear, not easy to break, suitable for both small and large load winches.

Drawing of Electric Combined Winch

Main Parameter

Installation Process — Reference

1. The positioning of the base of the marine winch from the centre line of the ship, the frame number position and the height from the midline of the deck must meet the requirements of the base drawing.

2. The installation and inspection of the marine winch base are qualified.

3. When using a steel backing plate, the plane of the base fixing backing plate should be processed first, the flatness is ≤2mm, the surface roughness is Ra3.2, and the outward slope is 1:100.

4. After installing the marine winch, use the hanging wire method or the laser method to confirm the horizontal axis of the marine winch drum, the tolerance is 3mm/m, and the height and the distance from the midship position are ±5mm, and the inspection is qualified.

5. Whisk with steel backing plate.

6. Epoxy resin casting pad.

7. Prepare copper gaskets. Before the winch fixing bolts are tightened, check that the gap between the winch base and the base fixing pad is less than 0.5mm, and no gaskets are allowed; when it is greater than 0.5mm, it is allowed to have no more than 3 thin copper gaskets, and it is not allowed Use a half sheet of spacers.
