The invention also provides a logging carriage which has a winding drum rotatably mounted in a body. A cable is wound about the drum, whereby the drum is rotated when the cable is pulled. A drop line sheave is rotatably mounted in the body and has a drop line extending thereabout. A drive mechanism mechanically couples the sheave to the drum, whereby rotation of the drum rotates the sheave to lower the drop line as the cable is pulled. There may be one or two other carriages, all the carriages being releasibly connected together.
