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.

A truck dumper including a material receiving hopper, a tilt table configured to dump a load from the truck or truck trailer into the material receiving hopper. The invention includes a stilling shed positioned above the material receiving hopper and at least one curtain baffle suspended below the roof of the stilling shed. The curtain baffles are positioned such that there is a gap located near the roof and an upper margin of the at least one curtain baffle through which air can flow. The invention further includes an air exhaust structure configured to exhaust dust laden air from the interior of the stilling shed.
