摘要：
Push-cables and associated apparatus and systems are disclosed. In one embodiment, a push-cable assembly for use with a pipe inspection system may include a push-cable element having a proximal end and a distal end, with a spring assembly having varying flexibility coupled to or near the distal end. The spring assembly may include an outer coiled spring having a proximal and a distal end, and an inner coiled spring nested at least partially within the outer coiled spring. A camera head and/or other elements such as a cutting or jetting apparatus may be coupled at or near the distal end.
