Knowledge of cross-country modification of winch

Off-road vehicles in addition to lifting the suspension, with anti-slip differential to improve off-road capability, the winch (WINCH) is one of important components.

In the West, the Army per 10-wheel-drive truck with a winch on at least one, not including engineering of the recovery vehicle (recovery vehicle is a chassis by a 6 × 6,8 × 8 or 50 tons of heavy truck tanks change, it is a large winch with a 2-4 engineering vehicles, specialized in the field into pit rescue truck tanks). WINCH importance is evident.

During World War I, due to poor road conditions at the time, in addition to other cities, suburbs full of stone and Wong Nai Road, an ordinary car because of poor rains the relationship between speed, it is easy to get stuck. At that time, some people use the winch from a boating pier be inspired to change it in the truck and drive it to the chain, this design is very successful.

To the Second World War, winch design has been very mature. PTO shaft with direct drive winch (called PTO that PowerTakeOff, transfer case and then in the separation of a straight shaft, the power output to the winch). U.S. expected to GPA and MB wheels easily on the battlefield into the sand, especially in the mud and snow. Therefore, in order to increase their ability to cross-country self-help, the U.S. military in the 19th century, developed the first generation of 40's small Jeep with the winch.

This winch and ship the same, but it is generally placed horizontally instead of straight up the form. More specifically, it is not around on top of cable or rope, but only a cylindrical drum cutter action. When using the PTO winch even simpler than the modern, as long as the driving engine and the winch side of the gear stick forward, the cylinder will immediately rotation. This time and then set in the twisted hemp rope drum 12 fixed circle, the other end of rope Zeyi staff adheres to the operator pulling, rope moving body will be twisted together with the transfer. As long as the operator does not pull the rope a relaxing, moving drum cutter is rotating but will not bring their own rope. The disadvantage is not reversed.

Famous BRADENWINCHCOMPANY is the first production car winch manufacturers. Now Liuzaishishang of BRADENWINCH small number, the year that PTO is not only GPA (small amphibious Jeep) of standard equipment, the body of the winch in the number of MB only 1200. 600 000 units compared MB, on average 500 years only one with BRADENWINCH, the ratio is small. In addition, the battlefield is not equipped with a winch of the MB is the special purpose vehicle project cars, to and from vehicles with worn or damaged winch war may be less.

After World War II, BRADENWINCH widely welcomed by farmers, because it put on a belt driven pump. I have a lot of cars MBJeep, starting from the 16-year-old, I hope to find a BRADENWINCH. Yet, even military vehicles to the members of the world and no one really read BRADENWINCH, we only saw the picture in history. But I have not given up, with more than a decade of time, until more recently from a septuagenarian in the hands of a German collector bought one. This is the ancestor of the jeep winch.

19th century 60's, electric winch started. Its advantage is light weight, low cost, self-loading Chaigai on a different car, and even if the engine does not work, can also operate winch. In the 19th century, the early 80s, the British army to WARNM8274-50 and M8000 on the Defender who used the U.S. military will WARNM12000 on Humvee (Hummer military vehicle Edition) body.

Because the PTO cost is too high, can not move to different types of vehicle use; plus the engine is not operating, the relationship between the winch will not operate, penetration is very low. The electric winch, small four wheel drive can be coupled with almost. Achillea out CAMELTROPHY the world is more than a decade of 8000 pounds with WARN winch, have gone through the worst traffic areas in the world; and InternationalOffroadChallengeofMalaysia (ie Rainforest Challenge) is a statement not winch can not participate in competitions, shows, major winch sex.

If long-distance cross-country team to travel within the team must be at least three vehicles equipped with a winch, because under the harsh natural environment at least three winch can operate freely. As the 1999-2000 "Qianxizhilv", a total of five cars, I 1, 2 and 5, are fitted with a winch truck, 3 and 4 are not equipped, for the cost issue, I did not use five winch. I have three cars were used for the three different types of WARN winch, they each have inferior long. My car is the No. 1 M8274-50, which is a high-speed racing winches. It features reliable, very fast, faster than other brands of winch more than three times, reaching 22.37 meters / minute, and there are 46 meters long wire. But it's bulky and heavy, only the modified cars and the Jeep Wrangler, etc. can be installed. About 11,500 Hong Kong dollars one. The No. 2 car is the M8000, which is the normal medium-sized Jeep, 2 tons of the preferred winch, which has 3600 kg of pulling force, reliable, weight only 34 kg and 30-meter-long steel wire, pulling speed of 8.8 per minute meters.

The No. 5 car is XD9000, it is relatively heavy and fast winch. It has 4100 kg pull, weight 39 kg, but also very reliable, the price of about 8,580 Hong Kong dollars / units. These three models are very popular winch models, is 2-2.25 tons of four-wheel choice.

The past two years, WARN M1500 winch was launched in HS9500 and their own special characteristics. HS9500 high-speed high-powered models, pull up to 4309 kg, speed of 18.9 m / min. Is L.C.80 good partner, about HK $ 10500 one. The M15000 is a small Hummer and 6 × 6 trucks, the best choice, pull up to 6800 kg! My Hummer just switch to the M15000. About 15,000 Hong Kong dollars one. To know which car best suits your winch, you must know that their cars in the country, and to understand the characteristics of each winch.

In addition to these five WARN winch and there is M12000, M10000, M6000, Z3500, T2500, A2000, U2500, UW1000 various models, and distinctive. M12000 winch which is heavy, it has a 5400 kg pull for more than 2.8 tons of heavy four-wheel.

The M10000 is one of heavy-duty winch, a 4500 kg pull, 9 meters per minute, the recovery rate of more than 2.5 tons for the heavy four-wheel drive use, such as Toyota LC80, LC100, etc.. Both winch also has a 38 m long steel wire. M6000 is 1.3 tons of choice for small four-wheel, speed of 14.8 m / min. The Z3500 is specifically designed for the 660CC small jeep, pulling a 1600 kg, 18-meter-long steel cable, 7.6 meters per minute can be recycled. T2500, A2000, U2500, UW1000 so small winch is designed for ATV and boat design. (ATV is about 250-300 kg of 4 × 4 all-terrain scooter, single drive. Boat winch used mainly for parking terminal.)

Correct choice of a suitable winch is very important. Tension and the weight of the car is directly proportional, in addition to the famous U.S. WARN winch, there RAMSEY winch plates, it produced RE12000R, RE8000R, REP8000R, REP6000R, REP5000R, PRO9000RX, RW4000, RW2500X versions. But they recovered more slowly, this is the biggest drawback. In addition, there SUPERWINCH brand, its model is not too much, but in the same slow speed recovery.

Many people may ask the recovery winch speed really so important? The answer is yes. Speed is important because if the car into a swamp, using the winch pulling speed, we can assist them out of the front pit, then the rear wheels will follow from the pit. If the winch is slow, skidding front wheel rotation pit will continue to open, forward, extrusion, reduces the chance of pit, winch bigger workload, but also very hard.

Sometimes encounter bad road, winch pulley also need help. In addition to steel wire pulley can change the direction, but also can pull double the winch. In addition to winch and on the period's presentation of the differential lock is required outside the off-road equipment. Hi-LiftJACK (high body lifter), desert and mud bridge plate is equally important. In the bad roads, HiLiftJACK can rise into the wheel pit, and then put sand in the pit area template or mud bridge, the wheel can be enough to re-lay down upon the friction and out of danger.

Facts have proved that as long as the match well, with the modified off-road vehicles can be any period of the Earth surface
