The elevator (1) of the present application comprises a drive (30), a chassis translatable on the ground, a platform, a lifting structure and a hydrodynamic system (S) comprising a reservoir (130), a hydrodynamic actuator and a circulation circuit (140). The circulation circuit includes a pump unit (170) drivable by a drive to deliver fluid into a delivery line (172) according to a delivery pressure that varies as a function of pressure regulation, a main distribution unit (190) connected to the delivery line, a boost unit (180) connected to the main distribution unit, and an auxiliary distribution unit (200) connected to the boost unit. The invention relates to a system for dispensing fluid from a lifting structure (110), comprising a pressurizing unit (182) connected to a delivery line through a branch supply line (181) and delivering fluid from the delivery line into the pressurizing line (182) by regulating the pressure of the fluid to a pressurizing pressure having a preset value and controlling the actuation of a first actuator (20, 120) acting on a component of the lifting structure (110), and an auxiliary dispensing unit (200) connected to the pressurizing line and delivering fluid from the pressurizing line into the pressurizing line (182) by regulating the pressure of the fluid to a pressurizing pressure having a preset value. And control the actuation of a second actuator (50, 70, 80, 81) acting on the auxiliary component (40, 60, 13A) comprising a brake release device.
