HOW TO USE THE WINCHES

This page is in response to requests on how to use the winches at Allhallows Yacht Club.

There are two winches at the club both 3 phase 415v.They both operate in exactly the same way which is described below.

They both feature a built in fail safe brake which is actuated on release of the handle

 

This is the East Winch and is slightly larger than the West winch.It is composed of two parts,the handle for manual control and the electrical control panel shown on the right hand side.

Before using the winch ensure the pulley is connected to the eye Pulley mount loop shown in the next image.Notice the pulley lying disconnected.Generally it is in the way of low slung trailers used for race days.

It is safe to leave it connected at other times

 

I am making the assumption that a launch vehicle and boat is at the bottom of the ramp and needs pulling out. Here is where you need an extra pair of hands.

Notice also the lever with the white tube on the end.Looking at the lever face on it is held against the brake assy by the weight of the blocks at the other end of the shaft.You can just see them in this image.This is the fail safe position so that if you let go of the lever it locks tight against the brake preventing any wire being spooled off.

Moving the lever clockwise takes the brake off and allows the main drum to free spool.You can do this with the motor running or not.

Remember if you move the lever to the right you allow the drum to spool so be careful nothing is half way up the ramp without chocks!Remember also that if in doubt just let go of the lever ...it will apply the brake for you automatically.

Lets go through this again this time with the motor running.

Referring to the Electrical panel you will see a main switched isolator.If this is on you will see three LED's illuminated on the box to the right.See Image Left

Notice also the switch to the right.This is for the main motor contactor.When you switch this on the motor will start and the chain will be driven.Note that no power is transmitted to the drum as the lever is held against the brake.You will also see a 4th Led illuminated to signify the motor is on although the noise will qualify this!

With an extra pair of hands grab hold of the end of the cable and start pulling it from the drum.At the same time move the lever to the mid position ie just off the brake.Do not pull it hard clockwise or you will start reeling it in!!Just enough to release the brake.

Pull the cable from the drum and connect to whatever at the bottom of the ramp.Preferably around somthing solid such as a towbar...no dont use the bumper!!

With the wire connected GENTLY move it further clockwise to apply take up to the drum.With practice you can slip this like a clutch to keep the wire taut.

Pull it harder clockwise to start pulling up the ramp.Make sure that if its a launch vehicle they do not drive it up and run over the wire.If the launch vehicle can continue to pull then get the launch vehicle to stop and chock the wheels or apply the foot brake.

Then move the lever to the mid position to allow the drum to freespool and release the cable from the object.Once its free then hard clockwise to reel in any slack cable.

Be extra careful with the wire..it can tear your hands to pieces.Preferable to wear gloves if possible.

When finished shut off the switch for the motor and turn off the main isolator.Bear in mind that the main isolator also feeds the two sockets on the control panel so this may need to be left switched on.Seek advice if not sure or if there are no other cables connected then shut it off.

If its a boat trailer only then pull it up to the top of the ramp and chock the wheels before removing the rope.

DO NOT ALLOW ANYONE BEHIND THE OBJECT BEING RETRIEVED AT ANY TIME.SEEK ASSISTANCE IF NOT SURE.
This device is extremely powerful due to the reduction gear and motor HP.
If in doubt refer to a club officer.
