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
A base beam used to support a self-propelled derrick rig, comprising:
- a longitudinally extending metal main beam having first and second opposite ends, a front side, a back side, a top and a bottom, the bottom is substantially planar;
- the main beam includes a central section approximately midway between the first and second ends thereof, the central section is reinforced between the top and the bottom, and the top of the central section is substantially planar;
- 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;
- and
- at least one guy attachment point on each of the first and second swing arms.
