Working Principle
How Does An Electric Anchor Windlass Work?
The power source of the electric windlass is an electric motor, which drives the main shaft to rotate after the large and small gears in the reduction box achieve multi-stage deceleration. Due to the high reduction ratio requirements, the reduction mechanism is relatively large.
The electric windlass anchor winch is mainly used on small and medium-sized ships, and is generally suitable for anchor chains with a diameter of 16mm-93mm.
Hydraulic Anchor Windlass
Technical Parameters
Model | Hydraulic Windlass |
Dia of anchor chain/rope | ø12mm – ø128mm |
Speed | 9-11 m/min |
Load capacity | 1 ton- 100 ton |
Certificate | BV, ABS, DNV, RMRS, etc |
Advantages of Hydraulic Anchor Windlass
Compared with the electric windlass, under the same power, the hydraulic windlass has the advantages of compact size, light weight, stable operation, and can realize stepless speed regulation and automatically prevent overload.
Working Principle
How Does A Hydraulic Windlass Work?
The Electro-hydraulic Windlass is driven by the electric motor to drive the hydraulic pump, and the generated oil pressure drives the oil motor, and then the windlass is operated through the reducer (or without the reducer).
The hydraulic windlass is widely used on modern large and medium-sized ships, and is suitable for anchor chains with a diameters of 16mm-120mm.
Features And Options of Aicrane Anchor Windlass
- Electric or hydraulic drive
- Single or double gypsy
- Warping head
- Manually or hydraulically operated clutch
- Manually or hydraulically operated band brake
- Local or remote control
- Emergency release
What Is A Windlass Used For?
The windlass is used to retract and release anchors and anchor chains. It is usually installed on the main deck of the fore and stern part of the ship for anchoring and mooring of the ship. The warping head on both sides of the gypsy can be used for line handling.

More Information About Marine Anchor Windlass
1. Structure of Marine Anchor Windlass
At present, the anchor windlass on ship is mainly electric windlass and hydraulic windlass. The windlass system is mainly composed of base, support, anchor chain wheel, brake, gearbox, electronic control system, etc. The electric windlass for boats has an electric motor, and the hydraulic windlass has a hydraulic pump station.
2. Main Technical Requirements of Marine Windlass
- The windlass is driven by an independent prime mover or electric motor.If the hydraulic pipeline of the hydraulic windlass is connected with other deck machinery pipelines, it is to be ensured that the normal operation of the windlass is not affected.
- The small boat windlass should have the ability to work continuously for 30 minutes when an anchor is pulled up from a depth of 82.5m to a depth of 27.5m at an average speed of not less than 9m/min.
- The small anchor windlass should be able to work continuously for 2 minutes under the action of overload tension (no speed required). The overload tension should not be less than 1.5 times the working load.
- The gypsy of the windlass boat anchor winch should be equipped with a reliable brake. After the brake is applied, it shall be able to withstand the static tension of 45% of the breaking load of the anchor chain or steel cable, or withstand the maximum static load on the anchor chain.
- The chain brake should be able to withstand the test load equivalent to the anchor chain, and its stress should not be greater than 90% of the yield point of its material.
- Installing a windlass on a boat should ensure that the chain cylinder, chain brake, and chain wheel are in a line when the anchor chain is drawn out.
3. Different Anchoring Methods Using A Boat Anchor Windlass
Ship anchoring is a common method of berthing. According to different waters, meteorological conditions and operational requirements, the anchoring methods are different. The commonly used methods are bow anchoring, stern anchoring, and bow and stern anchoring:
- Bow anchoring
Since the wind and current on the hull are the smallest when anchoring at the bow, bow anchoring is the most common way for ships to anchor. Single anchor at the bow is suitable for good weather conditions and short berthing time, while the double anchor at the bow is suitable for situations where activities are restricted or the waters are affected by large wind waves and rapids.
- Stern anchoring
It is mostly used for inland watercrafts. When the ship sails along the water, it can avoid the vessel turning around due to anchoring.
- Bow and stern anchoring
It is used when vessels are subjected to the effects of rising and falling cycles, and the active waters are restricted.
The anchoring process of a ship is as follows:
The anchor chain or cable-linked anchor on the ship is thrown into the water to land on the ground and bite into the soil. The holding force generated by the anchor is consolidated with the bottom of the water, thus the ship is firmly anchored in the predetermined position.
4. Classification of Anchor Chains
According to the manufacturing method, the anchor chains can be classified into cast steel anchor chains, welded anchor chains, and forged anchor chains.
According to the structure of the chain link, the anchor chains can be divided into gear chains and gearless chains. The strength of a gear chain is about 20% greater than that of a gearless chain.
According to the purpose: marine anchor chain and marine mooring chain.
Divided by the steel grade, the boat anchor chains can be AM1, AM2, and AM3, with strength AM1<AM2<AM3. AM1 is not suitable for high-holding anchors, and AM3 is only suitable for chain diameters above 20.5mm.
