The deformation index commonly used in the rolling process of aluminum alloy

Deformation direction deformation index calculation formula meaning and application name Symbol high deformation pressure reduction amount △h △h=Hh indicates the change amount of rolling thickness before and after rolling, which is convenient for production operation, and directly adjusts the roll gap processing rate ε 1、ε= △h/H(%)2, ε=ln(H/h) 1, Approximate deformation degree, easy to use on the production site; 2. The degree of true deformation, often used in theoretical analysis and calculation of the width of wide deformation △B △B=B1 -Bo production site used to express the width of the increase in the relative width εb εb = △ B / Bo is commonly used in theoretical analysis longitudinal deformation elongation δ δ = [(L1-L0) / L0] × 100% is mainly used to indicate the material pull Extensibility extension coefficient of tensile test λ λ = L1/L0 for theoretical analysis and actual calculation

24v Offroad Winch

The capacity of offroad winches differ from 2000lbs to 20000lbs. Normally winch line pull below 5000lbs are for UTV/ATV, winch line pull between 8000lbs and 15000 lbs are for cars like Jeeps, winches over 15000lbs are designed for trucks. Below are some 4X4 winches for sale.

There are also DC electric hydraulic winches from 10000lbs t0 20000lbs. To install such winches, hydraulic pumps are needed.

Car Winches or electrical 4x4 winches, they are commonly available with either a 12V DC or a 24 V DC motor.so confirm the winch voltage you need before buying a winch. And the voltage does not affect the winch motor housing shape, however the inside motor quality sometimes will. There`s almost no difference between the price of 12v and 24v.

Electric Recovery Winches are powered by a motor that runs off either your vehicle's battery or power steering pump. The vehicle's battery power is transferred through the winch's motor to the gear train, causing the winch drum to rotate the rope or cable in a rapid spinning motion.

When choose an electric winch, take the maximum load that you expect to winch and multiply it by 1.5, then you`ll know which one to choose.

The weight rating of these off road winches is based on the first wrap of the cable around the drum. With each layer of cable, the pull capacity actually drops, so when in doubt, go larger. Below is an example of winch performance of each layer for your reference.

Besides, if you need a fast speed winch, pls also take a look at the gear ratio your suppliers offered. As for winches in 12000lbs, the normal gear ratio is 265:1, if you prefer fast speed, you may choose 158:1, which means the actually line of pull may be smaller at the same time.
