Abstract

The lift (1) comprises a drive (30), a chassis that is capable of translational movement on the ground, a platform, an elevating structure and a hydraulic system (S) comprising a reservoir (130), hydraulic actuators and a circulation circuit (140). The circulation circuit comprises a pump unit (170), which can be driven by the drive to deliver a fluid into a delivery line (172) at a delivery pressure which can be varied according to a pressure regulation, a main distribution unit (190), which is connected to the delivery line and which controls the actuation of first actuators (20, 120) acting on parts of the elevating structure (110), a boost unit (180), which is connected to the delivery line by a branched-off supply line (181) and which sends the fluid from the latter into a boost line (182) by regulating the pressure to a boost pressure having a preset value, and an accessory distribution unit (200), which is connected to the boost line and which controls the actuation of second actuators (50, 70, 80, 81) acting on accessory parts (40, 60, 13A), including a brake release device.
