Abstract
A hydraulic system for construction equipment having a float function is provided. The hydraulic system can perform ground leveling as making a boom descend due to its own weight without using hydraulic fluid that is discharged from a hydraulic pump. The hydraulic system includes a holding logic poppet mounted in the float valve to prevent an abrupt descending of the boom due to leakage of the hydraulic fluid through a flow path between the main control valve and the float valve during the operation of the boom cylinders.
