Electric Towing Winch

Electric Towing Winch

Application

The electric towing winch has been applied to various types of tugboats and offshore work vessels for rescue and towing purposes. It consists of drum, brake, clutch, pedestal, spooling device, motor and so on. Usually, the towing winch is equipped with an emergency release device. When the towed ship sinks, fires and explosions and other accidents, the emergency release device can quickly release the rope, disconnect the two ships, and ensure the safety of the tugboad. Motors have single-speed, double-speed and variable-speed motors.

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.
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.
	Other brands	High power consumption, relatively poor quality.
	ABB/WEG/Siemens	Good quality, high cost, long delivery time.
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.
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.

Repair and Maintenance Advice

1. Always check whether the bolts, rivets, pins and other connecting parts are loose or fall off, especially for bearing seat bolts and anchor bolts. If they are loose, they should be tightened in time. 

2. Regularly check the gear meshing condition of the reduction box, check whether the gears are moving, whether the teeth are worn out, whether there are serious damages such as cracks and broken teeth; whether the oil in the fuel tank is enough, and whether the oil has deteriorated and precipitated. 

3. Always check whether the lubricating oil pump is running normally, whether the oil flow of each lubricating part is smooth and quantitative, whether the oil ring is rotating, and whether the oil temperature is normal, otherwise it should be adjusted and replaced in time.

4. Regularly check whether the brake wheel, brake disc, brake shoe, transmission mechanism, hydraulic station, etc. of the braking system are flexible and normal and whether the gap between the brake block and the brake disc (or brake wheel) meets the regulations, and the safety of the brake Whether the action is normal, whether the brake operating handle still has a reserve trip of 1/4 of the full stroke when it is used in the library, whether the brake counterweight is cushioned by foreign objects, and whether the disc brake disc spring fails, otherwise deal with and adjust in a timely manner. 

5. Frequently check the dynamic condition of the lead screw and nut of the depth indicator, and test the deceleration alarm bell and the overwinding protection switch. If the action is insensitive, it should be adjusted and tightened in time. 

6. Check the burnout of the contact contacts of the master controller, electromagnet contactor, various relay signal devices, etc. If there is burnout, repair or replace the contacts in time.

7. Check whether the wire rope is neatly wound on the drum, whether the rope head is fixed firmly, and check the inspection records of wire rope breakage and wear. 

8. Check whether the coupling is loose, deformed and missing parts, check the axial displacement and clearance of the coupling, whether the radial displacement and end face inclination meet the requirements, replace the damaged elastic rubber ring, and make up for the pins that have fallen off, nuts, washers and other fasteners. 

9. Always wipe the equipment, clean the floating dust and sundries, and keep the machine bright and clean.
