Abstract:
A variable angle drilling machine comprises a frame and a pipe handling system. The pipe handling system is capable of moving from a horizontal to a second orientation and comprises a magazine, a carriage assembly, a shuttle assembly, and a pipe section biasing assembly. The pipe section biasing assembly biases pipe sections towards an open side of the magazine in order for the shuttle assembly to grab a pipe section from the magazine and transport the pipe section to the carriage assembly. The carriage assembly makes up or breaks up a drill string during variable angle boring operations.
