Calculating Tension on Cable & Winch for Remote Heliportable Wireline Work

[rpotts]

I need to calculate the tension on a cable. cable comes off a winch, travels up at a 45 deg angle over a pulley which is 2m above the height of the winch. The cable goes down at a 45 deg angle and connects to a 7m pipe 2m from a hinge point directly below the pulley. the pipe weighs 7kg/m.
This unit is going to be used in remote heliportable wireline work in northern Alberta. The 7m pipe has a cable system on the end that is used to lift pressure control equipment on to the well.
I want to put some engeneering support to the design so we can be confident of the cable size and winch capacity prior to building the system.

What you describe is not quite clear. Can you post a figure?

You don't go to a web forum for engineering design advice that can affect worker safety and the safety of others. You hire a licensed and qualified engineer to do the calculations for you.
