PLEASE NOTE !!
A winch is designed ONLY for pulling along a horizontal surface,
NOT FOR LIFTING or securing a load... under any circumstances!!!
USING A WINCH FOR SUCH PURPOSE IS OUTSIDE OF THE DESIGNED USE.
For lifting purposes you will require a 'Hoist'

CORRECT EVALUATION OF WINCH USAGE
In order to understand the correct usage procedure for all winching applications
please read the following information, Failure to understand and execute
this procedure in the use of any electric winch will cause a considerable
shorter life cycle to your new winch.
The information provided below will help you in selecting the correct
model of winch to suit your required application.
Winches used under certain conditions i.e salvage & recovery every
day use will require a much higher output motor than that of a less frequently
used winch which is pulling only small boats etc from water onto a trailer.
Remember - When a vehicles weight is approx 2t and the requirement is
to load the vehicle up ramps onto a recovery vehicle then the weight of
the vehicle is greater than its previous weight when on level ground,
the requirement of the winch is far greater due to the fact that it obviously
takes more effort to pull the same weight up a gradient than along a flat
surface. The required ratio of a winch for this application would be minimum
9000lb (4.1t) Please note the 9000lb rating is a maximum on the first
layer of cable on level ground.
Winches are rated at their 'Straight line pull' capabilities and therefore
it is essential to evaluate the use of the winch prior to purchase. The
same applies in a 4x4 vehicle situation when pulling a 4x4 either up a
gradient or out of 2 feet of mud!
In Plain English - A 2ton winch would not meet with the requirement of
4x4 uphill climbing for a vehicle weighing 2 tonnes, the requirement of
the winch for this task would be 9000lbs minimum. Any smaller winch would
inevitably prove to be both dangerous and false economy causing premiture
failure.
People often purchase a winch rated at 2 ton which may be the same as
their vehicles weight, they are then dissapointed when the winch fails
under use due to wrongly selecting their requirement upon purchase. Tradewinch
will not supply any winch for a 4x4 of less than 9000lb Series wound specification.
Winches need to be powerful enough to pull your vehicle whilst overcoming
the added resistance caused by obstacles such as moving water, mud, snow
or sand or on a steep hill. As a general guide the requirement of your
winch must have a maximum line pull of at least 2.5 times the vehicles
weight.
How Winches are rated :
Load and speed vary according to how much wire rope is on the drum, The
first layer of rope on the drum delivers the slowest speed and the maximum
load. A full drum delivers the maximum speed and the minimum load. For
this reason, all vehicle winches are rated at their first layer capabilities
Please see examples below
Vehicle Transporter / Recovery Vehicles
A vehicle weighing 1 ton winched up the ramps of a recovery vehicle with
a 30% gradient would convert the vehicle weight whilst on the gradient
to a mass weight of 2.5 ton. Therefore using a 1 ton winch for a 1 ton
vehicle for these conditions would be totally un-suitable. A minimum requirement
of your winch would be 2.5 ton for a 1 ton vehicle + any multible thereafter.
i.e a 2 ton vehicle would require 2.5 times the line pull i.e 2.5 x 2
ton = 5 ton minimum. Any vehicles which may have other restrictions such
as flat tyres, binding brakes or wheels missing etc would multiply the
require line immensley therefore these factors MUST be taken into consideration
when purchasing a new winch.
The use of a snatch block is strongly advised along with shortening the
cable will increase the power of your winch.
All winches are rated at maximum power on the first layer of cable only.
All instruction booklets must be read and observed prior to first use.
Our suggested requirement for entry level to the above would be our 8500lb
winch with the 5.5 HP motor (Minimum)
4 x4 Vehicle examples
A 4x4 vehicle with a kerb weight of 2 tons requiring pulling up a gradient
of 20% in mud would convert the weight of the vehicle to 5.5 tons. Therefore
a 2 ton winch would be totally unsuitable for this application. A minimum
requirement of your winch would be 5.5 tons.
The use of a snatch block is highly recommended under these conditions.
Please note - It is strongly advised that these factors are taken into
consideration when selecting your new winch.
Our suggested requirement for entry level to the above would be our Platinum
Range 9,000lbs with the 5.5 HP Motor (Minimum)
IMPORTANT NOTICE -
The use of a winch for the lifting or transportation of persons is strictly
forbidden, the wire bond is secured only by a automatic brake system which
could fail under certain conditions risk of death could occur.
Tradewinch will not be held responsible for any accidents, failure of
equipment or otherwise under any misuse conditions detailed here.
