Q1 What is rated line pull? How does it help me to decide which winch to buy?
Rated line capacity is the pulling capacity of a winch which it can handle during
the single line pull, without the use of any other devise such as snatch block.
This is the measure of pull on the level ground on the first layer. While selecting
a winch choose the winch the rated line pull of which is at least 50% greater than
your gross vehicle weight (Weight of the vehicle loaded fully). This is done taking
in account the fact that the there is a drop of 12% for every next wrap on the drum.
A 9,000 lbs
winch would have line pull of nearly 7, 000 lbs on the third wrap.
Q2 What is line speed? Does buying a winch with faster
line speed help me?
Line speed is the measure of length of line that a winch can spool off in one minute.
Most Milemarker winches have higher line speeds. The more expensive a winch greater
is its line speed. But at the same time you have to be more cautious with winches
having higher line speeds.
Q3 How can I cope with the extra load my electrical winch
would put on my electric system?
Installation of an electric winch requires the strengthening of the electrical system.
You will require a heavy duty (high output) alternator with an output of at least
100 Amps. You should fit a high capacity battery, or go for a dual battery setup
with some sort of electronic battery management system. If you have other high power
devices, sound system, lights etc, It is better to consider a separate high power
wiring loom. Installation of an easily accessible emergency power cut off switch
is also a good idea to tide over an emergency situation.
After you have high power battery and alternator, next step is to check that all
connections are Clean. The best grounding systems will use large diameter cables
(such as welding cables), the battery negative post connects to the engine block,
the alternator ground connects to the engine (usually through its case) and then
the frame is connected to the engine using a grounding strap. Proper and clean connections
help you in saving power.
Compared to your vehicle's other electrical components, winches draw huge amounts
of current and can completely drain your battery or overload your alternator in
a matter of minutes, so take care to install proper kind of battery set-up.
Q4 I have heard that Electric winches are not safe to use,
what are the disadvantages of using an electric winch?
An electric winch uses the battery reserve power so you can winch your vehicle as
long as your batteries can supply. An electric winch generally draws about 300 Amps
to 1000 Amps and the alternator is only rated at around 80 amps.
Electric winches get very hot if used continuously, this excessive heating will
damage the motor, and the current draw may damage the batteries if you allow them
to use too often. The high power consumption and low duty cycles are the obvious
disadvantages of the electric winch.
The electric winches are not able to perform in extreme weather conditions, such
as in a desert where the electric motor overheats quickly or when it becomes very
cold and the battery loses its power.
Q5 Can I use any other Wireless Remote with a Mile Marker
Yes, Mile Marker winches are compatible with most wireless remotes.
Q6 What are the safety considerations which I need to keep
in mind while winching?
Never forget to take your leather gloves with you. Handling the cable with bare
hands, is quite dangerous, a frayed cable can cut your skin. Getting your fingers
caught in the cable as it winds onto the drum is the most common accident that takes
place during winching. Always use the remote control cable when winching, and keep
every person out of range of the cable.
The addition of the following items and accessories will greatly increase your winch's
usefulness - Tree saver straps (never wrap a cable directly round a tree, you will
kill the tree and kink your cable), a couple of clevis pins, snatch blocks, a choke
chain and of course thick leather gloves. Most of these items are provided with
Winch Accessory Kit.
A broken winch cable can have enough force in its whiplash to cut through a truck's
roof and windshield A cable that hits a small tree will tear the tree down. A cable
that hits a large tree can wrap tightly around a tree so a person behind the tree
is not necessarily safe. Solid objects such as hooks and snatch blocks will fly
through anything, including a truck's hood, if a cable breaks.
Take care to ask any person around the winching area to stand well out of range
of the cable and never in line with the cable. Furthermore, if a cable breaks, the
truck being winched may roll downhill, give strict instructions to people not to
stand downhill if any vehicle is to be winched.
However, in the case of a long distance pull you may not see a person and it is
a good practice to use a heavy blanket or jacket over the wire rope which can serve
as a visual warning so that the by-standers do not trip over it. And in case a rope
failure occurs the weight of the cloth will act as a damper and help prevent the
broken rope from whipping. A
synthetic winch rope helps to prevent such accidents.
Q7 Which type of maintenance does the winch require for
Winch requires maintenance on a regular basis. Lubricate all required points and
bolts. Inspect all winch mounts,
pulleys, straps and clevis pins; remove any of the part if it is damaged, or showing
signs of fatigue. Check that all the above parts are free of moisture. Inspect your
remote control lead and electrical system for damage and chaffed insulation.
Make sure all terminals are corrosion free and tight. After each trip unspool the
cable. Check for kinks and frayed strands (damaged cables should be replaced). Lubricate
cable with a chain and cable lubricant (normal greasewill collect dirt) and wind
back onto drum.
If you take the above precautions your winch would give you long trouble free service.
Q8 What about the installation of a receiver mounted
Receiver mounted winches are very useful,
but remember their static pull load is limited by the receiver they fit into. For
a class III hitch that is 5000lbs. one can use a winch that is really only suitable
for downsize trucks and jeeps.
The Milemarker 9,000 pound winch bolts directly to
the Mile Marker cradle mount
with four grade 8 bolts. With the winch removed the Multi-mount receiver cradle
is barely noticeable. With a front and rear receiver hitch and a winch
mount plate supplied by the Mile Marker, the winch can easily be transferred from
the front to the rear of the vehicle, making recovery from either direction possible.
You also need a disconnect kit
to activate the solenoid.
It is important to note that the integrated Draw-Tite portable winch plate restricts
you to not exceed a pull angle of 45 degrees horizontally or 15 degrees vertically
when winching on 9000 lbs. This system is not fit for heavy duty use, but for semi-hardcore
and moderate wheelers, it has no match. It can be used with most of the trucks and
SUVs built today.
