Wire rope is an essential ingredient in most modern construction, and historically served a variety of purposes, leading to the development of shipping, railroading, elevators, telegraphs, mining, cable cars and airplanes.
The earliest evidence of wire rope used in construction was found in the ancient ruins of Nemeveh near Babylon, dating back to B. Evidence of modern use of wire rope in structural elements can be seen in the Brooklyn, Cincinnati, Williamsburg, Manhattan, George Washington and the Golden Gate Bridges. Measure the length from the top of clan bane vtm side of the flange to the bottom on the same side.
Record as the flange diameter. Measure the length of the space in between the top and bottom flanges, and record as the drum length. Measure the distance between the top layer of the rope to the outside edge of the drum flange.
Record the measurement as the freeboard measurement. Determine if your drum surface is smooth or grooved, and select the appropriate option located next to the Unit of Measure field. Subtract the barrel diameter in inches from the flange diameter in inches. Divide this number by two to find value A.

On this page we will go thru each item of information and you can decide if it is needed for your application:. A winch is for pulling along the ground up to a 30 degree incline. A hoist is for pulling at incline from 30 degrees to loads that are free suspended and vertical. There are some situations above the 30 degree rule where a winch can still be used.
An example is if there is some other type mechanism that will hold the load in the case of failure of the winch. Another example is if your load is dropping into the water. Because a hoist is lifting objects vertically and possibly above a persons head, an extra brake mechanism is needed. Be sure you check with the governing body for your application to be sure you have what you need.
What will power the winch? Manual - Hand Crank or Hand Wheel. A hand wheel will make lifting the load easier for the operator. Be sure to see what the gear ratio of the winch you purchase is. Also, check the amount of force needed to turn the crank of the winch or hoist to the pull the load you need.
Pneumatic - Air Powered. Pneumatic motors are expensive and very loud as compared to hydraulic. However, air compressors are much more available as compared to hydraulic power packs. Air winches are explosion proof and are suitable for situations where this feature is needed. Should you decide upon a pneumatic winch or hoist be sure to know what pressure and volume of air is required in order to power the unit you need.
If you do not supply the winch or hoist with the pressure pounds per square inch and amount cubic feet per minute of air needed, it will still operate, but at reduced line pull and speed. Electric power and electric motors are readily available and not costly.
This makes them suitable for a majority of applications. In addition, you don't need an air compressor or hydraulic power pack. The downsides are that faster speed and higher line pull units require larger power supply higher voltages and 3 phase quite quickly. Also electric winches and hoists are not explosion proof unless costly explosion proof motors and control boxes are included. When requesting a quote for an electric winch or hoist you must specify the hertz 50 or 60 Hzvolts, etc and phase 1 or 3.
If you have a source for hydraulic power, then hydraulic winches are cost effective and can reach very high line pull and line speed at reasonable cost. Should you decide upon a hydraulic winch or hoist be sure to know what pressure and volume of oil is required in order to power the unit you need.

If you do not supply the winch or hoist with the pressure and amount of air needed, it will still operate, but at reduced line pull and speed. Line pull needed how heavy is maximum load? You must determine how much pull pounds or KG that the winch or hoist will need to overcome.
This may not always be easy. Certainly it will be less than 5 tons. See section 12 below to learn how to compute. Another consideration is if you should multi part the line. A 2 part line runs from the winch drum, thru a pulley at the load and then back to the winch or near the winch and secured. The more pulley used the greater the line pull of the winch but the slower it will operate.
Line speed needed how fast does the line need to pay in and out?Get some cool 4x4 tech every couple of weeks:. We respect your email privacy.

Hi leep While I agree with boo1 and here to chill, your capacity to lift will be limited by the tensile strength of the cable, also bear in mind as the cable wraps onto the winch drum the torque requirement to lift will also increase.
Can you provide more details like speed of lift, cable strength etc, remember also that when starting to lift the cable as to accelerate the load from rest.Visit clubcar.

Before proceeding to the motor torque and speed calculations the following variables need to be determined:. Bare drum line pull Bare drum line speed Bare drum radius Gearbox ratio if any.
Drum torque. The drum torque required to achieve the desired line pull increases as the number of rope layers on the drum increases. The drum torque required to achieve a desired bare-drum line pull can be calculated using the following formula:. In metric units. Note that the figure calculated here is the required drum torque. If no gearing is used between the drum and hydraulic motor, the shaft torque required from the hydraulic motor T m equals drum torque T d.
If a reduction gearbox is used, the torque multiplication of the gear ratio must be considered. By downloading this document you acknowledge acceptance of our Terms and Conditions of Use. Motor torque. If a reduction gearbox is used, the gearbox input torque required from the hydraulic motor will be less than the required drum torque and can be calculated as follows:. Drum speed. The drum speed required to achieve the desired line speed decreases as the number of rope layers on the drum increases.
Motor speed. Motor shaft speed required to achieve a desired bare-drum line speed can be calculated using the following formula:. R min. At this point, the torque and shaft speed required from the hydraulic motor to drive the winch have been determined.

Description: Winch Drive Calculations.To enable the correct selection of winch, motor and gearbox, it is essential that basic application parameters as Load and Speed are known and understood. Below a brief explanation is given about the data and calculations required for the primary winch selection.
The essence of winching is to move objects from one position to another by means of a length of rope. The rope is fixed to the object at one end, and to the winch drum on the other. Power is expressed in kilo Watts kW. In the past and on the North American market power was expressed in horsepower which is about 0, kW. Torque is expressed in Newton metres Nmformerly kilogram metresand in some markets in foot pounds. The higher the speed at a given loadthe more power we need.
With the required amount of power kW determined, the amount of torque Nm involved in the application must be determined. Depending on the effective drum radius and the load the torque at gearbox and motor level can be calculated. The amount of torque at gearbox level is important to make sure a sufficiently strong gearbox is chosen, and at motor level to make sure the load can be actually moved. For winches with only one layer of rope this is a constant factor.
For winches with multiple layers the distance is a variable, and depends on the amount of rope wound on the drum. The amount of torque and power resulting from the calculation must be translated into a motor type and size. Depending on what is locally available in terms of power supply or even available physical space, the motor emerging from the calculations may prove beyond what is possible.
Also make sure the motor can be physically installed onto the gearbox, and that effective motor power and torque and in some cases motor speed fall inside the operational limits of the gearbox. In case of doubt increase the gearbox dimension or configuration or reduce the winch performance.
Selecting the correct gearbox, the maximum torque value during operation or with an applied brake is leading. In case of doubt go up one size of gearbox, the possibly too generous extra torque capacity of the gearbox will translate into a longer life.
Make sure the calculated gearbox can be installed into or onto the winch and that it matches with the selected motor and resulting motor performance. When special demands or requirements are present, it may be required to calculate with a non- standard drum. The minimum drum diameter follows from the minimum rope bending radius. A larger diameter drum stores more rope for a given width, but also increases the effective drum radius and therewith the required torque for a given load.
Make sure the diameter used in the calculation is an "existing" diameter i. Alternative dimensions can be specified, but will increase the cost of the modification unnecessary. Depending on the regulation applicable the upper rope layer must remain rope diameters below the edge of the flange. As with drum diameters it is advisable to use "existing" flange diameters. Again make sure an "existing" diameter is selected for the flanges, the same logic as for the drum diameter applies.
These dimensions can be derived from the catalogue information, and when a longer than standard drum is specified, the extra length can simply be added to the catalogue figures. Special care is required when bigger longer motors or gearboxes than standard are specified, or when extra equipment like clutches or band brakes are added to winches.
Make sure that the available space for installing the winch is sufficient for installing the winch itself and for the extra space required needed to operate and maintain the winch.
