Description

RED Winch Cobra 2

This winch is the ultimate high performance compact single motor electric winch, capable of being used in the most demanding conditions.

The Cobra is an excellent choice when it comes to the best competition single motor electric winch for your vehicle.

RED Winches has designed and developed this high performance winch for 4x4 competition use and serious motorsport events.

All products at RED winches have been through an extensive design and testing program before going on sale so you can use all our winches with confidence they will not let you down.

Power

Capable of pulling a minimum of 4 Tonnes the winch can easily get you out of trouble quickly, quietly and with minimum effort time and time again. The winch body is CNC machined from high grade heat treated aluminium from solid billets. We only use the best machine tools and machining processes to ensure stress is kept to a minimum and strength to its maximum. With its patented air free spool and brake system the Cobra offers something previously unavailable on a winch to the off-road and motorsport sectors.

Cobra package you will get:

Cobra winch Anodised RED, with ‘Patented’ air brake system

Air Switch for free-spool and solenoid for brake operation built (to be mounted seperatly next to winch)

Albright Heavy Duty Solenoids x 1

Copper Bus Bar System

Hard Anodised Aluminium fairlead

Lower mounting interface blocks x 2, used to save you damaging the expensive end housings when mounting

As with all our winches, the Cobra winch does not come with a rope, this has to be purchased seperately.

The air brake system

Spring pressure applies a steel disc to the brake material when the winch is not in use.
This applies the brake and stops the winch from spooling out.

When you winch in or out you energise your Albright solenoids this also energises the air solenoid valve for the brake. This then allows air to go into a specially designed chamber that releases the brake instantly. When you remove your winching finger from the controls the air solenoid dumps the air and the springs apply the brake disc onto the brake pads. We can vary the number of springs in the brake to suit the weight of the vehicle if necessary but so far this has not be needed. More springs equals larger braking force but more abrupt stopping which can cause snatching which we do not recomend.

One nice feature is when you are lowering out you can switch your isolator off to the winch (no power to the motors) and just flick the winch out button on your dash. This fires the air solenoid and releases the brake and your vehicle only pulls out rope for the amount of drop your vehicle needs or moves. This means compared to normal winching you do not get overrun or excess rope causing snatching and jerking as the vehicle takes up the slack rope that has been spooled out. This design has been submitted for full patent and is currently protected and patent pending.

We would expect a set of brake pads to last at least a season if not 2 seasons due to the material they are made from.

Brake pad sets and all spare parts can be orderd if needed.

The air free-spool

A piston in the end of the drive shaft moves a large clutch plate in and out off drive pins.
The drive is provided by a large drive shaft and splined end.

Electrical Power

The electrical power of this winch is currently supplied by a BOW Motor II. These are supplied normally with a 12v supply from your vehicle. The high power Albright solenoid is used to switch direction of the motor and to also provide a feed to the 12v brake system. These are all proven components and widely available and have been used extensively in the competition and motorsport industry by RED Winches for many years.

Power of the winch is variable due to how your vehicle is setup and the quality of the components used. It also depends on the scale of electrical losses or inefficiencies in the wiring system. As a general rule running 12v DC BOW Motor II with a good powerful supply you can expect the winch to pull 4 tonnes...possibly more under certain conditions. Tested with x2 Odyssey PC1500 batteries, 12V supply and ground connections made with 70mm2 cable.

Weights

Winch: 37kg (Without Rope)

Shipping Weight: 40kg (with no rope or accessories)

Drive System

The drive is mechanically provided by a solid steel hardened clutch plate. This is a very tough hardened plate that engages and disengages by an air supply. The clutch plate is driven from the planetary gearbox by a solid steel central shaft. The drive system has been built for strength and durability. When not engaged the ‘free-spool’ of the Viper drum is only between two roller bearings so it extremely free moving allowing the co-driver to run freely with the rope.

Drum Capacity & Pulling Capacity

The drum can hold 30m (90ft) of 11mm rope. At the end of the drum is a rope securing bolt pattern. This has been specially designed by RED winches to make rope changing easy and simple. All that is required is 1 Allen key to clamp the rope with the four bolts through the middle of the rope.
Line pulling power with electrics is in a world of its own as you probably know…and depends heavily on the quality of your electrical setup
I would say the Cobra can easily pull as a minimum 500kg directly (hanging vertically with no support from wheels) But this does mean you will need:

Twin alternators, one for the vehicle and one for the winching batteries (120A Min)
Two batteries supplying the winch motors with enough power, and one battery for the vehicle electrics
At least 70mm² high quality electrical cable
Clean electrical joints and if in areas prone to water joints should have conductive grease applied

We have been honest in our facts and have not blown the figures up high only to impress.....we work on real data as engineers....

Brakes

The patented designed brakes work in a way that they only come off when a voltage is applied. When a signal is sent to the winch to operate either forward or reverse that same signal is used to energise the magnets and release the brakes. The brakes are 12v and will always need 12v to operate which is the same voltage used to operate the solenoids. The brake pad is made from a high strength composite ensuring a high strength braking grip, and longevity of the wearing surfaces.

Gearbox

The gearbox has been specifically designed for strength, power and ease of service. All gears are manufactured from 655-M13 nickel chromium molybdenum steel and case hardened to give maximum strength (1100 N/mm²) and excellent durability. The end cover is sealed via an o-ring and groove, ensuring a watertight seal. Once the cover is removed access to all gears is possible and only takes 5mins to change all gears and re-assemble. The gearbox runs in grease not oil making it much easier to service in the field.

Serviceability

The Cobra has been designed with both competition use and servicing in mind. Two mounting blocks are provided to interface between the winch and the mounting frame. This reduces the risk of stripping the threads in the winch casing. The free-spool assembly is held in place with machine screws for ease of service.
