Abstract

This disclosure introduces chassis alignment assemblies for aligning a chassis with a support structure. An example implementation includes a chassis having first wheels, a jacking assembly coupled to the chassis and having second wheels, and a jacking actuation member operable to vertically displace the second wheels relative to the chassis to engage the ground and raise the first wheels off of the ground such that the jacking assembly supports an end of the chassis. Another example implementation includes a chassis, having first wheels, and an outrigger assembly having: a frame movable between transport and alignment orientations; second wheels; and an outrigger actuation member operable to move the frame relative to the chassis.

First claim

What is claimed is:

1. A method, comprising:
positioning a modular silo in a substantially lateral orientation on a chassis, wherein the chassis comprises:
a set of wheels supporting the chassis on a ground; and
a jacking assembly comprising at least one wheel;

operating the jacking assembly to raise an end of the chassis to an alignment orientation such that the end of the chassis is at least partially supported by the at least one wheel of the jacking assembly and such that the set of wheels of the chassis are unloaded;
moving the chassis while in the alignment orientation such that portions of the modular silo and a mobile support structure (MSS) overlap; and
erecting the modular silo from the substantially lateral position to a substantially upright position while the chassis is in the alignment orientation.

2. The method of claim 1 wherein the jacking assembly further comprises at least one axle and the at least one wheel is operably connected to the at least one axle.

3. The method of claim 2 wherein the at least one axle is a fixed wheel axle.

4. The method of claim 1 wherein the MSS comprises an expandable base, wherein the expandable base comprises an alignment guide, and wherein the method further comprises:
moving the expandable base from a transport orientation to an operational orientation; and
then aligning the chassis with the MSS, during the movement of the chassis while in the alignment orientation, by utilizing the alignment guide for aligning the jacking assembly relative to the MSS.

5. The method of claim 1 further comprising connecting the modular silo and the MSS after erecting the modular silo.

6. A method, comprising:
positioning a modular silo in a substantially lateral orientation on a chassis, wherein the chassis comprises an outrigger assembly having at least one wheel;
actuating the outrigger assembly to move a frame of the outrigger assembly downward into an alignment orientation such that the frame extends beyond an end of the chassis and is substantially aligned with an expandable base of a mobile support structure (MSS) to which the modular silo is to be assembled;
moving the chassis toward the MSS while the outrigger assembly is in the alignment orientation such that portions of the modular silo and the expandable base overlap and such that the at least one wheel of the outrigger assembly engages a track of the expandable base; and
erecting the modular silo from the substantially lateral orientation to a substantially upright orientation while the frame is in the alignment orientation.

7. The method of claim 6 further comprising moving the expandable base from a transport orientation to an operational orientation before actuating the outrigger assembly and moving the chassis toward the MSS.

8. The method of claim 6 wherein actuating the outrigger assembly comprises actuating an outrigger actuation member of the outrigger assembly to move the frame of the outrigger assembly from a transport orientation to the alignment orientation.
