Abstract
Improvements to base beams and self-propelled derrick rigs are described. The base beam can have two or more stabilizer arms which can be deployed. The base beam is also designed to support the derrick rig. An optional counterweight assembly can be connected to the front of the rig. The self-propelled derrick rig can be easily and quickly mounted to the base beam, and when mounted, the assembly will be able to withstand high hook loads and wind loading without the danger of the rig coming off of its wheels or falling over.
Claims19
An assembly, comprising:
- a base beam that includes:
- a longitudinally extending metal main beam having first and second opposite ends, a front side, a back side, a top and a bottom, and a central section;
- first and second swing arms pivotally attached to the main beam, the swing arms are pivotable relative to the main beam between a retracted position where the first and second swing arms are generally parallel to the main beam and a fully extended position where the first and second swing arms are not parallel to the main beam;
- a self-propelled derrick rig with a derrick structure adjacent a first end of the rig that is disposed in a raised position, a driver's cab, and an engine that provides power for propelling the rig;
- a base of the derrick structure is supported on the central section of the main beam on the top thereof;
- a plurality of guys extending between the derrick structure and the remainder of the rig;
- and
- a plurality of guys extending between the derrick structure and the base beam.
