Front panel opening/closing system interlocking with cab tilting

摘要

A front panel opening/closing system includes a hydraulic cylinder, a tilt cylinder, a tilt pump, and a valve. The hydraulic cylinder is connected to a front panel of a cap to perform an operation of opening/closing the front panel. The tilt cylinder is connected to the cap to perform an operation of tilting the cap. The tilt pump is connected to the hydraulic cylinder and the tilt cylinder through a hydraulic line to provide oil pressure. The valve is disposed at the hydraulic line of the tilt pump and the tilt cylinder. When the valve is positioned at a first position, the oil pressure is supplied from a hydraulic pump to the hydraulic cylinder and the tilt cylinder through the hydraulic line. When the valve is positioned at a second position, the oil pressure is supplied from the hydraulic pump only to the tilt cylinder through the hydraulic line.
