The other end of each of the loop slings is adapted to extend around opposite ends of the axle between the respective wheel and a bearing journal box mounted on the terminal end of the axle. A second pair of loop slings are also secured to at one end to the master link and arranged to be secured at the other end to the motor housing to prevent rotation thereof during the hoisting operation. Each of the loop slings comprises a core of high performance endless parallel fibers enclosed in a tubular abrasion resistant covering. The first pair of slings further include a cut and abrasion resistant sleeve surrounding the tubular covering over the length thereof which is adapted to engage the axle and wheel.
