Trenchlesspedia explains Cradle Machine
Cradle boring was especially popular during the 1960s and ‘70s in the construction of many cross-country pipelines. The design of a cradle boring machine makes starting the job much quicker and faster. Rather than a full-fledged entrance pit, only a starter trench is required. During the heyday of cradle boring, cradle machine crews would usually work ahead of regular pipe crews.
The cradle of the machine protects the operator and provides space to work. A cradle machine excavates with an auger in front as it advances casing.through the ground. Once the excavation is complete, it removes the auger, installs the pipe product through the casing, and then removes the casing.
