A load-handling vehicle comprising a load-handling device comprising at least: - a load-handling member, - a hydraulic cylinder for raising the or at least one of the load-handling members, said lifting cylinder comprising a lifting chamber and a lowering chamber, - a hydraulic fluid source comprising at least one hydraulic fluid distribution system and a reservoir, - a first fluid connection connecting the lifting chamber of the lifting cylinder with said hydraulic fluid source, - a second fluid connection connecting the lowering chamber of the lifting cylinder with said hydraulic fluid source, characterized in that the first fluid connection comprises a safety valve open in the direction of circulation of fluid from the hydraulic fluid source to the lifting chamber and normally closed in the direction of circulation from the lifting chamber to the hydraulic fluid source, the load-handling device comprises a pressure-sensitive valve disposed on the second fluid connection, this valve being configured to go from the closed position to the open position based on the pressure prevailing on the portion of the first fluid connection extending between the safety valve and the hydraulic fluid source, the load-handling device further comprising a unidirectional fluid circulation line that can be blocked connecting the first and second fluid connections (8, 9) for looped circulation of fluid from the lowering chamber to the lifting chamber in the open state of said line, the member for blocking said line being configured to be moved between an open position and a closed position based on the pressure prevailing on the portion of the second fluid connection between the valve and the hydraulic fluid source. - a load-handling member, - a hydraulic cylinder for raising the or at least one of the load-handling members, said lifting cylinder comprising a lifting chamber and a lowering chamber, - a hydraulic fluid source comprising at least one hydraulic fluid distribution system and a reservoir, - a first fluid connection connecting the lifting chamber of the lifting cylinder with said hydraulic fluid source, - a second fluid connection connecting the lowering chamber of the lifting cylinder with said hydraulic fluid source, characterized in that the first fluid connection comprises a safety valve open in the direction of circulation of fluid from the hydraulic fluid source to the lifting chamber and normally closed in the direction of circulation from the lifting chamber to the hydraulic fluid source, the load-handling device comprises a pressure-sensitive valve disposed on the second fluid connection, this valve being configured to go from the closed position to the open position based on the pressure prevailing on the portion of the first fluid connection extending between the safety valve and the hydraulic fluid source, the load-handling device further comprising a unidirectional fluid circulation line that can be blocked connecting the first and second fluid connections (8, 9) for looped circulation of fluid from the lowering chamber to the lifting chamber in the open state of said line, the member for blocking said line being configured to be moved between an open position and a closed position based on the pressure prevailing on the portion of the second fluid connection between the valve and the hydraulic fluid source.
