Pros of Hydraulic Winch

There are a number of factors to be considered when selecting the most suitable marine hydraulic winch or electric winch to be used. Some of the most common uses of winches in the maritime industry are as anchor handling and towing winches, mooring winches or ship launch-use winches. There are several factors to consider for marine-use winches, especially the size of the vessel, the displacement, energy efficiency among other factors.

The most popularly used winches are electric or hydraulic winches. When choosing a winch for marine application, the energy efficiency is very important. Electric winches use power directly from generator sets. Hydraulic winches on the other hand use fluid power to work which utilizes hydraulic systems and a motor pump between the generator set and the winch. Hydraulic winches however, requires 20-30% more electric power for its performance due to this power conversion system. Hydraulic-powered winches are the best kind of winches for vessels that have generator sets large enough for crane loads. A hydraulic winch has the capacity to carry very heavy loads.

For winches on ships, the size of the vessel will help determine the type of winch to get. A hydraulic winch is the best option for larger vessels because of the size of hydraulic system equipment and is often very heavy. Hydraulic winches is the better option for vessels that need to move very heavy cargo.

When choosing a hydraulic winch, you will have to consider the electric systems that will control the winch. The controls of the hydraulic winch include control panel displays, joysticks, switches and pushbuttons. This can make the system that operates the winch complex and it is important to get one whose wheelhouse controls, remote stations and local winch controls are automated and working as they should. You also want to get a hydraulic winch whose parts you can replace easily. The winch will often wear at the fluid and mechanical interfaces as well as o rings and seals. You need to be able to get the spare parts easily as these parts will require to be replaced periodically when they wear out. For MAX Groups’ winches, we usually slot in a packet of several free common spare parts together with your shipment when you purchase from MAX Groups Marine.

You also need to consider the installation of a hydraulic winch and its related system. Some of the equipment and systems that you have to install include piping, hydraulic components, fittings among other additional equipment.

Some of the benefits of using a hydraulic winch is that it is likely to last for long as it is very durable. With proper care and maintenance such as replacing worn out parts, a hydraulic winch will serve you for a very long time. It has the capacity to operate very heavy loads especially for those that an electric winch does not have the capacity for. They also work continuously as long as the engine is running. We usually advise electric winches to be used for smaller projects, as without electric supply, it will not function. For hydraulic winches, it can work for long periods of time as long as the engine is working. Especially during ship launching and vessel upgrading projects, when the tide situation plays a role in the project operation, the winch may be required to perform consistently at longer periods of time. In that case, heavy vessels usually involve hydraulic-powered winches.

Ultimately, it really depends on all these factors and the application of the winch to decide which type of winch suits your use best. Learn more about MAX winches HERE.

8 Tips to Make Sure Mooring Winch & Anchor Windlass Works Perfectly

Mooring Winch / Anchor Winch / Anchor Windlass

8-quick-tips-anchor-windlass-mooring-winch

1. Make sure the foundation of mooring winch is in good stable condition. Tweet this!

An overall check for issues should be performed, especially the overall stability of the marine equipment itself. Most people tend to neglect the winch foundations. To ensure a safe operations environment, these details of the mooring winch should not be omitted.

2. Brake linings, hinge pins and drums have to be checked thoroughly. Tweet this!

Older winches in ships/boats may have to be checked for possible faulty brake gear and the condition of brake drums below the lining have to be assessed to be safe.  Establish a policy to test winch brakes should do the job. 60% of the mooring line’s minimum breaking load should be held by the primary brake. Be careful that the brake adjustment screw may have been tightened to its limit after years of excessive wear on brake linings. If that is the case, more maintenance and renewal may be required.

3. Insulation tests are extremely important for safety. (for electric mooring winches located in gas hazardous areas) Tweet this!

An “Ex” rating is HIGHLY RECOMMENDED if the marine winch is in such areas as the rating certifies that the internal explosion can be withstood without igniting the external atmosphere. Insulation tests should provide higher than 1 Megaohm resistance to make sure the electric-powered winch is safe.

4. Checks should be performed regularly on mooring wires and ropes. Tweet this!

IMPORTANT NOTE: should there be more than 3 broken wires in any strand, the damaged part definitely needs to be removed and respliced. Lubrication using preservatives should not be overlooked too as it protects the wires and strands. Regular maintenance of mooring wires and ropes is vital to keep the winch working effectively and efficiently.

5. Rollers should be able to turn freely and be well greased at all times. Tweet this!

This is to prevent materials or trash getting stuck in between and damage the mooring winch during operations.

6. Checks on the anchors, locking bars and cables of the anchor winch/ anchor windlass should be performed. Tweet this!

This is to ensure the anchors, cables and locking bars are in safe working conditions. Locking bars have to be able to lock and secure the chain when vessel is at anchor so that the brakes do not have to take the full load of the cable. Cables should also be made sure it is strong for action.

7. Mooring lines should be correctly reeled on drums. Tweet this!

Band brakes are designed to work in a single direction. Thus, the mooring lines have to be reeled in the correct arrangement depending on manufacturer’s guidance.

8. Never leave a winch in gear with the winch band brake on. Tweet this!

Powered mooring lines secured on brakes should witness the winches out of gear. Should the brake render, the electric or hydraulic drive may be badly damaged.

Anchor Winch: Options for the Marine Industry

Max Group is one of the trusted supplier of marine supplies in the world. We offer innovative and quality products. Our company specializes in the most advanced winches, designed for the marine industry. We have established a reputation for delivering high quality machinery. You can choose an anchor winch from one of the many varieties available.

Anchoring is the process of having the ship to stop at mid sea or at the port. An anchor is used to hold the ship steady and at the same place, unaffected by the strong waves. The anchoring process involves dropping and lifting the anchor. Anchor winch is used for such situations.

Every anchor winch is designed with a particular vessel size in mind. Other factors that determine the type of product that you select include rode selection, windage, and anchor size. We have a wide range of capstans and windlasses to suit different boat/ship models. You can choose between a horizontal and vertical anchor winch depending on your individual requirements. However, bigger ships tend to favour horizontal windlass over vertical windlass.

Vertical Windlass

This anchor winch is popular and it helps to reduce slipping. It offers great chain control because the chainwell is wrapped by the anchor rode. This machinery is allowed to be placed below decks, therefore lowering the center of gravity.

Horizontal Windlass

This product is mounted above the deck. The machinery is often times more self-contained, thus, more protected.

Motor Options

We offer different types of motors including hydraulic and electric. The motor watt does not affect the performance of the boat winch. It is important to find an efficient winch by considering the performance of both the motor and gearbox. Hydraulic motors can be used as an alternative source of power for electric motors. Their speed is constant under both heavy and light loads. The hydraulic motors are able to operate almost continuously and they are also safer because of various safety features including valves to relieve pressure. We offer the most advanced hydraulic systems. These systems offer you a centrally controlled, efficient, low maintenance and integrated power source.

Anchor Winch Performance

It is easy to determine anchor winch performance by simply looking at the features available. Look at the anchor winch lift and the speed at which its lifts. Maximum pull capacity and working load are two of the most important considerations you need to make when you are making a choice. The working load refers to how much the winch is capable of pulling after the anchor is lifted. Our staff can help you find the right working load and pull capacity to meet your specific needs.

Safety

We are committed to ensuring that our products are safe for use. All the products come with a variety of safety features. Our electric windlasses use circuit breakers during the installation process. This ensures that your cables and motor are well protected in case the boat winch is overloaded. We also offer a wide range of accessories to enhance safety when you are using an anchor winch. We have chain snubbers and chain stoppers that can be used to promote anchor safety. These accessories make sure the anchor does not self-launch unintentionally. They also protect the anchor winch from damage.

Why Choose a Hydraulic Winch over an Electrical One

Electric winch

Marine industry winches, no matter hydraulic or electric, are commonly used in the industry. There are many reasons why a hydraulic winch is better than the electrical one. Unlike the electrical one, it doesn’t require a powerful battery to operate. Another key attribute is that it can pull for longer periods of time and harder without overheating as compared to an equal sized electrical unit. Another great advantage of the winch is that it is capable of operating while completely submerged in water.

When used in cold climates, the hydraulic winch is also superior. The hydraulic fluid gets pre-warmed before it can enter the winch motor. After getting warm, the hydraulic fluid is able to keep the motor and this makes it possible for it to operate in cold climates. The warm winch doesn’t only pull harder but produce better results.

When presented with a difficult pull, the equipment isn’t damaged by ordinary use and neither does it overheat. It continues pulling as hard from the start until completion. The winching vessel’s engine doesn’t require to be operated at a higher speed than an idle winch. The power steering of the boat or ship offers the required power right away from idle.

However, the hydraulic winch also has its own share of drawbacks. One of these is that it only works when the engine is running. At times, this may render it useless.

The battery system of a boat/vessel is typically designed to operate at high-power output for a brief period like the starting of the engine. On the other hand, according to its design, the hydraulic winch operates at full power draw and for longer periods. With an electric winch, the battery of the vehicle as well as its system is overworked when it tries to supply power to the winch. It is for this reason that the hydraulic winch is more reliable and durable.

It is also easier to repair a hydraulic winch as compared to the electrical one. When the electric winch breaks down, you have to engage the services of an electrician buy a number of items and seek a stable environment to fix it. On the other hand, when a hydraulic winch breaks down it is usually in one of the valves and these can even be repaired even when the vessel is still on water. Therefore, there are many reasons why you should pick a hydraulic winch.

When buying this equipment, you need to decide the amount of weight that will be pulled. Use the weight class to decide the winch motor and winch capacity. This should also help you to set budget as the high capacity winches are more expensive.

One place where you can buy your hydraulic winch is at MAX Groups Marine. They have a wide range of products that are used in marine, ports, ship yards, salvage companies and many other areas.

Tips for Safe Mooring

The mooring process is one of the most important and delicate tasks marine workers have to perform. Mooring accidents happen from time to time mostly due to lack of concentration and factors that can be avoided. Some seafarers call these factors the ‘death traps’ on ships. Equipped with the know-how of how to avoid these ‘death traps’, the occurrence of accidents involving innocent seafarers can be reduced. Deck crew has to be familiar with safety precautions and have great understanding of the deck machineries.

Fenders

First of all, the ports must be well equipped with high quality rubber fenders / dock fenders. Fenders acts as a ‘dock bumper’ to absorb collision energy and minimise the reaction force to both surfaces. This prevents damage to the quay and ship during contact. Due to being vulnerable to friction, jetty fenders should be protected from shear forces by covers and frontal pads made from other materials. Besides, some are designed in a roller system so that the ship can slide along the wharf without ripping out the fenders.

Pre-tensioning 

Pre-tensioning the mooring lines uses friction to prevent the fore and aft movement of the vessel when heaved tight up against the rubber fenders. A certain degree of softness factor for the fenders would help during mooring process as they allow effective pre-tensioning. Fenders’ change in shape during contact when compressed would help ensure that relatively small movements of the vessel would not result in fore and aft motion of the vessel due to friction.

Weather Condition & Deck Condition

Weather condition that involves the wind and current condition should be considered before the mooring operation. Should a future weather condition be challenging for the mooring operation, the safety of the crew should be taken into consideration. Seafarers should be aware of ‘snap back zones’ and rope bight to avoid accidents during the operation. One of the most overlooked mistake is to allow extra personnel on the deck during mooring. Those who are not assisting in the mooring operation should not be on the mooring station. It is also important to keep the mooring station clear with no unused ropes and equipment on the deck.

Mooring Winch & Offshore Winds

Mooring winch should be properly maintained and perform at an efficient level. Winch brakes and other parts should be thoroughly checked before mooring. Cargo berths are becoming increasingly exposed to offshore winds. It is the trend these days that ports were redeveloped in order to allow more mechanised cargo handling, and traditional warehouses with shelters were omitted. Short loading platforms provide little shelter for bulk carriers and tankers. This should highlight other issues that accompanies exposure to offshre winds.

After Mooring

After the mooring process, the checking of the load on mooring ropes and the condition of the rope are still equally important. Any of the mooring lines are not more than 55% of its Maximum Breaking Load (MBL) to prevent the rope from snapping and causing undesired accidents. Changes in ballast condition of the ship require the lines to be tightened accordingly. These are just some of factors to be considered during the mooring operation. The process requires all personnel involved to be highly diligent and equipment to be efficient to prevent mooring accidents from happening.
