52. tandard winch has a rated breaking strength of 2000 Ib 907 kg using the recommended design ratio of 1 to 5 The rated break strength gives a maximum hanging weight of 400 Ib 181 kg Because each application is different it is impossible for Geotech to anticipate the exact hanging weight of your system Hanging weight is the sum of pump weight the weight of all discharge piping and the weight of any water trapped inside the piping Although it is unlikely that you will exceed the 400 Ib 181 kg maximum Geotech highly recommends that you take the time to calculate the hanging weight of your system before deployment Use the following procedure to calculate hanging weight 1 Weigh your pump assembly including the intake and any attached probes 2 The weight of the discharge piping can be calculated by weighing a sample length and multiplying by the number of feet suspended in the well For example 1 5 ID rubber hose weighs approximately 1 Ib 45 kg per foot 3 Therefore 100 30 m of this hose will weigh 100 Ibs 45 kg 3 The weight of the water in the discharge piping can be estimated by calculating the volume of water in the piping and then converting the volume to weight as follows Volume in gallons Volume in x inside radius of pipe in x length of pipe in Gallons 0 00433 x Volume in3 1 Gallon water 8 325 Ibs Weight of Water Ibs 2 8 325 x Gallons Volume in liters Volume cm 2 z x
