What is a hydraulic winch & How Does It Work

What is a Hydraulic winch?

Winches are devices used to pull a heavy load. It is typically used to pull in, let out, or otherwise adjust the tension of a cable or rope.

Hydraulic winch is one type of winch which is an important equipment used in the marine industry. Hydraulic winch operates off with the hydraulic system of a vehicle, in most cases, the power steering pump. It does not require a strong battery for smooth functioning. It has a noticeable feature to work perfectly when being drowned completely in water. One of the best attributes of the winch is its ability to pull for longer periods without overheating. Which is longer than an electric winch.

Hydraulic winch is ideally suited to heavy duty marine applications to perform anchoring, towing as well as lifting and hauling heavy objects. It can be adapted to both offshore and onshore applications.

The main benefit of hydraulic winch is that they have a 100% duty cycle and are fully submersible. Having a 100% duty cycle means that without any negative effects, it can run constantly.

How does Hydraulic Winch work?

Hydraulic winch works by using a fluid in a confined space. It uses a pump to create a pressure differential. This pressure differential involves having a low pressure fluid stored in a reservoir before the pump that becomes supported inside of the pump which moves to the driven component and back to the reservoir.

Along with the reservoir, pump, and lines, there will be several valves that control the flow in the system.

Another noticeable advantage of the hydraulic winch in vehicle-mounted applications is its beneficial operation in cold weather. It is because of the power steering pump, the hydraulic fluid is warmed before it is about to enter to the winch motor.

The warm winch is able to pull harder than a cold winch and makes a better result. The warm hydraulic fluid keeps the motor warm and ready to operate even in cold weather conditions.

In practical situation, a winch can be pulled as hard as it can be, until it is completed. The hydraulic winches are designed in a way that they will not be overheated with a hard pull.

Hydraulic winch is made to operate with complete power for a long period of time. The battery system of any vehicle is supposed to operate at a high-power for only a short period of time.

A normal winch design will work best when the engine of the vehicle is on. In some instances, It’s winch usage can be terminated considering this fact.

The major fact while working with a hydraulic winch design is to deeply observe where you are going to use it. The size and weight of the vehicle must also be taken under consideration, where the winch will be mounted.

Features of hydraulic winch

High efficiency- This winch can work easily even after long term use and heating conditions.

High performance- Comparing to an electric winch, hydraulic winch will not be overheated with a long-time hard pull.

High strength- Hydraulic winch specially is designed for the most challenging task on both land

and sea. It has strong construction with a long working life.

Reliability and durability- Hydraulic winch can work perfectly in the harshest environments. It can operate for a long time with complete power.

Features like automatic braking, emergency stop button, drum locking system, pawl brake and over travel prevention system will provide maximum protection.

Uses Of Hydraulic Winch

The hydraulic winch is more efficient than an electric winch. This type of winch is more suitable for tough jobs on land and water. This heavy duty winch is commonly used on the boats, on the shore to carry out a number of different tasks and at docks.

The hydraulic winch, as the name suggests, is powered by a hydraulic system. It is able to deliver great power in order to handle a big job. The energy efficiency is very important while choosing a winch for marine application. Electric winches use power directly from generator sets. On the contrary, hydraulic winches use fluid power to work which utilizes hydraulic systems and a motor pump between the generator set and the winch.

Hydraulic winch has the capacity to carry huge loads. This type of winches has generator sets large enough for crane loads.

Hydraulic winches are the better option for vessels that need to move heavy cargo. Because of the size of hydraulic system equipment hydraulic winch is the best option for larger vessels.
