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.
Claims8
A method of supporting a self-propelled derrick rig having a derrick structure, the derrick structure is disposed adjacent to a first end of the rig and is movable between a raised position and a lowered position, the method comprising:
- arranging a base beam on the ground, and deploying stabilizer arms that are connected to the base beam to a deployed position;
- arranging the self-propelled derrick rig adjacent to the base beam;
- raising the derrick structure of the self-propelled derrick rig to the raised position;
- attaching a base end of the derrick structure to the base beam;
- attaching a plurality of guys between the derrick structure and the remainder of the rig;
- and
- attaching a plurality of guys between the derrick structure and the base beam.
