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.

Methods of supporting a self-propelled derrick rig

A cart for filling intermodal shipping containers with a bulk particulate material, such as grain, includes a hopper to receive the bulk material and a belt conveyor to deliver the material to the container. The conveyor is positioned external of the container and throws the material along an arcuate path to the opposite end of the container whereby the container is substantially filled without the need to extend the conveyor into the container. The cart is supported on wheels to be moved where needed. The cart can straddle a standard truck trailer carrying a container so that the container need not be removed from the trailer for filling. The conveyor height is variable to reach a container on a truck trailer or on the ground. The cart width can also be reduced for road transport.
