A trailer transit mixer is disclosed which includes two oppositely positioned support members at least one of which is pivotably attached to a center frame and to a supporting wheel structure. Power means extend between and are secured to at least one of the support members and the center frame and upon activation the power means cause pivoting of the support members to which they are attached to contract the trailer transit mixer.

A trailer transit mixer including two oppositely positioned pairs of support members pivotably attached to a center frame and to forward and rear wheel structures. Power means extending between and secured to the pairs of support members and the center frame when activated cause pivoting of the support members to contract the trailer transit mixer.

A mixer attachment for reception in or substitute for the forwardly directed scoop provided on the front end of a mining vehicle, the mixer being primarily adapted for concrete which is applied to the mine walls by a companion machine, and includes a supporting means for storing the mixer in a draining position when not in use.

A support system for a boom mounted on a truck includes four outriggers mounted to the boom pedestal which can be folded against the pedestal or extended to provide a wide base for supporting the boom. Each outrigger has an inboard leg member pivotally mounted to the truck and driven by a hydraulic cylinder. An outboard leg member is pivotally mounted to the outer end of the inboard leg member and is caused to pivot relative to the inboard leg member at approximately twice the pivot rate thereof and in the opposite direction. The outriggers may be extended by a single operation of the hydraulic cylinder. The means for rotating the outboard leg member causes the outrigger not to drag along the ground until it is finally placed. Means are provided for preventing pivotal motion of the legs beyond predetermined positions.
