Glossary of Special Winch

Mechanical Advantage
The factor by which a winch multiplies the force or torque put into it to move an item

● Pulleys also increase the mechanical advantage.

● A1,500-lb, single-speed hand winch has a maximum mechanical advantage of 49:1 at its most effective (with one layer of cable on the drum). This mechanical advantage can decrease to 15:1 as the cable or strap winds around the drum. The greater a machine's mechanical advantage, the greater its output force compared to its input force.

Gear Ratio
The number of revolutions a larger gear makes in relation to the smaller gear

● The higher the gear ratio, the more efficient the pulling.

● A 1,400-lb hand winch has a gear ratio of 4.4:1. A larger capacity winch, such as a 2,500-lb, has a gear ratio of 17.3:1. Worm gear winches with a 2,000-lb capacity provide up to 40:1 gear ratio. Light-duty electric winches have gear ratios up to 570:1.

Freespooling or Freewheeling
● The ability to freely pull cable from the drum without turning the crank or unwinding.

● Saves time and energy when attaching cable or strap to a load.

How to Service Special Winch: A Step-by-Step Guide

Preparation: Essential steps before you start
Before you begin servicing your special winch, proper preparation is crucial to ensure a smooth and clean process. Here are some steps to prepare:

Tools and diagrams: Ensure you have all necessary tools and materials at hand. Additionally, obtain an exploded diagram of your special winch model to guide you through the process. This diagram acts as a visual aid for part identification and placement. We have ours laminated and in the service kit.

Protect your space: Lay towels around the work area on the deck to protect it and minimize the chance of parts bouncing away during disassembly. If you're working near the side of the boat, drape towels over the lifelines to prevent any parts from potentially disappearing overboard.

Skin protection: Wear gloves to shield your skin from grease and dirt associated with special winch maintenance. Consider wearing two pairs of gloves; as you approach the final stages of reassembly, you can remove the outer dirty pair to keep the freshly serviced special winch clean.

Step 1: Disassembly
Begin by removing the special winch drum. Most special winches allow you to lift the drum straight off the base after removing the circlip or screw at the top of the spindle. Keep all small parts in a tray to avoid losing them.

Step 2: Cleaning
Clean all parts thoroughly using bespoke degreaser or diesel. Remove all the old grease, salt, and grime from the gears and bearings using a rag, toothpick and a soft brush. Ensure all parts are completely clean, free from degreaser and dry before re-greasing.

Step 3: Inspection
Inspect all components for wear and damage. Pay special attention to the pawls and springs, which are prone to wear due to their crucial role in the special winch mechanism. Replace any worn or damaged parts using spares from your service kit.

Step 4: Lubrication
Apply marine grease generously to the gears. The grease should coat the gears evenly but not excessively—too much grease can attract more dirt. Oil the pawls and springs lightly with machine oil to ensure smooth operation. Be cautious not to over-lubricate, as this can lead to sluggish pawl action. Never put grease on the pawls or springs.

Step 5: Reassembly
Carefully reassemble the special winch, ensuring all parts are correctly aligned and seated, using the special winch diagram for certainty. Replace the drum on the base and secure any circlips or screws removed during disassembly.

Step 6: Function check
Once reassembled, rotate the special winch handle to ensure smooth operation. There should be no sticking or grinding noises. If the special winch does not operate smoothly, double-check assembly and lubrication.

Step 7: Maintenance schedule
Regular maintenance is key to prolonging the life of your special winch. Due to heavy use, we service our special winches every 12 weeks. You likely won't need anything like such regular servicing but they must be done at least once a season.

FAQ

Q: What is special winch?

A: A special winch, often referred to as a manual hand winch or manual winch, is a compact and portable device used for lifting, lowering, or pulling heavy objects. It typically consists of a drum or spool, a hand-operated crank or handle, and a ratcheting mechanism.

Q: How does winch work?

A: The drum is connected to the large sprocket and this is connected to the small sprocket and then this in turn has a connection to the crank. The cable is wound up or down on the drum of the winch with a circular motion, causing the load to move horizontally or vertically, depending on the direction of the cable.

Q: How much can special winch pull?

A: Makes it easier to move an item by mechanical advantage. Available in all cranking types - hand crank, loop, ratchet styles. Designed for use with cable or strap. Capacities: 400 to 4,000 lbs.

Q: How to increase the speed of special winch?

A: Another way to increase the speed of a winch is to use a shorter handle, typically an 8" (203 mm) handle. The 8" handle is faster because it swings in a smaller arc and a crew can rotate the handle faster.

Q: What is the use of special winch?

A: The operator must crank the handle to wind the wire or rope onto a spool/drum, and this generates enough force to move the load in question. This type of winch is typically used in construction work and recreational settings such as off-roading to lift or pull machinery, cars and other heavy items.

Q: What size special winch do I need?

A: As a general rule of thumb, aim for a winch with a capacity of at least 1.5 times the weight of your vehicle. This ensures sufficient power for most recovery scenarios while accounting for additional factors like incline, traction, and resistance.

Q: What ratio is special winch?

A: A commonly used ratio of boat size to winch capacity is 2 to 1. Example: a 2,200 lb boat requires a 1,100 lb winch. There are, however, many factors to consider in selecting the proper size winch which are beyond the control of the winch manufacturer.

Q: What is the function of the special winch?

A: Special winch is a tool for moving a load both horizontally and vertically. The load is connected to the hand winch by a steel cable or a synthetic rope. A winch consists of a crank, a transmission, a drum, a cable, a brake and the housing.
