This winch rendering should be taken as the design value for a bollard. Instead, a tension T (force per unit length) is maintained in the cable when the upward force of the crane (redirected by a pulley at the top of the apparatus) exactly balances the weight of the load. Where the speed is high and the load value is low, fleet angle should be more towards 0. The acceleration is very short and therefore can be ignored here. Calculation method of allowable length for electric wire. In this demonstration you can see that winching with an extreme side angle for a long period without correctly spooling the winch line causes the line to bunch on one side of the drum. 2 40. I am working on a project to make a winch lighter. Most of the cases a mechanical design engineer only needs to put input and the software tools give the output in desired format. The cable goes down at a 45 deg angle and connects to a 7m pipe 2m from a hinge point directly below the pulley. 3. This is not the driver reaction time but the system reaction time.
