ABSTRACT:
This invention is a device for removing an oil cooler from a diesel locomotive, having one suspension point, and having a laterally extending upper arm, a vertical arm, and a laterally extending lower arm that cradles and supports a laterally extending probe, which is attached in pivotal fashion to a pair of lifting plates that are removably affixed to the oil cooler. The upper arm has a lifting clevice attached to a point central to the load, and a counterweight that balances the device from that central point. When the device is lifted by crane or other methods from the lifting clevis, the oil cooler is balanced laterally while at the same time maintaining an acute angle similar to the angle that the oil cooler maintains when secured in the locomotive.
