A cab suspension and repositioning system () for a truck includes a control arm assembly () having two control arms () with distal ends pivotably attached to a truck chassis () and proximal ends pivotably attached to a cab (), and one or more follower control arms () having a distal end pivotably attached to the chassis () and a proximal end pivotably attached to the cab (). Cab suspension assemblies () releasably lock the cab () to the chassis () during operation. The control arm assembly () further provides motion control to the cab (). Hydraulic cylinders () engage the control arm assembly () and are operable to move the cab () between an operating position adjacent the chassis and an access position away from the chassis () substantially without rotating the cab (). A control system () powers the cylinders () and controls the transition between the operating and access positions.

Cab suspension and repositioning system

A chassis for a vehicle is suitable for mounting the engine of the vehicle between the forward and rear axle assemblies of the vehicle. A first forward rail is positioned opposite a second forward rail, and an engine cradle is positioned between the forward and rear axle assemblies. The engine cradle has first and second upper rails. A forward portion of the first upper rail is angled toward the second upper rail, and a rear portion of the first upper rail is angled toward the second upper rail. A middle portion of the first upper rail is parallel to a middle portion of the second upper rail. The engine cradle further includes first and second lower rails disposed below the first and second upper rails. A plurality of support members coupled the lower first and second lower rails to the first and second upper rails, respectively.
