    Default 15 000lbs winch installation on cruizer (pics)

    I will be doing a 15 000lbs winch installation today on a 4500 cruizer ldv. The problem is fitting it behind the bumper as the cavity is too small. The other problem is a strong enough installation for a 15 000lbs winch with a snatchblock that will double it so we will land up on 30 000 lbs with at least double safety factor. This all equates to 60 000lbs or 27t. So the minimum will be 8x m12 capscrews.

    Stefan hy dra nie so baie gewig nie, dis n trek aksie. Die mounting is in lyn met die chassis op altwee kante. Onthou dis 15000lbs op n lee spoel en omtrent 10 000 op n vol rol. Dus 6.8t of 13.6 t maks met n snatchblock op ,maks kraglewering. As jy vinnig rem sal jou krag op n sleepstang hoog wees met n sleepwa. Onthou n snatchrope breek op 12t [pofadder] en daar is mense wat die goed al gebreek het. So die forces is nie soveel meer nie.

    Herman, neem asb 'n foto waar die hele Cruiser aan 'n boom hang vir die manne.. Ek dink dit sal 'n smart foto wees!

    Surely andersom?
    A full spool will surely exert a bigger moment of force. Increasing as it fills up

    Pls educalate me

    The force on the rope will decrease as the reel fills up, but the force on the motor remains constant. If the force on the rope goes down, the force on the mountings/chassis will also go down. It will match the force on the rope.

    The torque remains constant (well almost)

    Torque = Force x radius

    As the spool winds up the radius increase, a constant torque and larger radius means the Force is reduced.

    I agree with Henri and Chris' posts regarding the reduction in pulling force.

    Winch manufacturers usually make the pull per layer information available.

    Here's the specs for a Warn M15000. As you can see Engel was close with his "about 10000lbs" statement, it is actually 9840lbs pulling force on layer 4 on the Warn winch.

    you have to see the size of the winch to appreciate the size!

    It's also interesting how few bulbar suppliers can fit a winch larger than 10'000lb on their bulbars. I have a 12'000lb and ARB could not supply a bar suitably rated unless I go for the industrial type bar. On the other hand Ironman Bulbar could. ARB said it would interfere with the airbag deployment.
