Went out on a service call a few weeks ago somehow the water got into the hydraulic oil on one of our cranes and froze in the lines. We wanted to move the crane home for some major repairs.The boom was in the air the crane would not move. option 1 was hord it in and drain it flush all the lines ect. I thought that sucked ass bad as it was cold as hell and windy. I took the fitting off my hydraulic portapower and used it to engage the boom clutch and lower the boom. then we lined the trailer up with the crane with operator in the seat i ran the track clutches ith my portapower. dit the same to unload it and bring it into the shop. i am now called the redneck hillbilly mechanic.
