A tilting system for a suspended cab of a work vehicle includes a hydraulic cylinder coupled to a chassis of the work vehicle at a first end and the suspended cab at a second end. Further, the hydraulic cylinder is configured to extend to drive the suspended cab to rotate from a lowered position to a raised position. In addition, the hydraulic cylinder is configured to be substantially horizontal while the suspended cab is in the lowered position.

Disclosed herein is an engine compartment soundproof cover device of a cab-over truck. The engine compartment soundproof cover device includes a soundproof cover, side covers, and a plurality of expandable connectors. The soundproof cover is installed below a cab in which a driver is seated and is configured to cover an upper portion of an engine compartment. The side covers are installed on chassis frames of both sides of the engine compartment and configured to come into contact with a lower end of the soundproof cover to seal both sides of the engine compartment. The plurality of expandable connecters is configured to connect the soundproof cover to a lower portion of the cab and capable of expanding toward the side covers to allow the lower end of the soundproof cover to be pressed against the side covers.
