    摘要: A hydraulically driven elevator or lift is provided with counterbalance means to at least partly counterbalance the load imposed by the load carrier or lift car. Operation of the counterbalance means, which includes a substantially constant volume of pressurised fluid, does not involve any interference with the working fluid of the hydraulic drive system.

    摘要: A hydraulic elevator, wherein first and second hydraulic jack units are provided in an elevator shaft with the vertical projection surface of the car between them. Each of the first and the second hydraulic jack units is composed of a hydraulic jack. A hoisting rope is passed around each of two hoisting wheels driven upward and downward by these hydraulic jacks. Each hoisting rope has a shaft side joining end fixed to the bottom of the hall and a car side joining end joined to the lower end of the car.

    摘要: A vertically oriented hydraulic power unit (40) for an elevator drive includes an outer tank (50) for drive fluid and an inner tank (88) for fluid used to submerge and cool a motor, the fluids being exchangeable to maintain temperature in the inner tank (88) at or below a specified maximum temperature. Oil returning from an elevator piston is fed into said inner tank (88) to keep the inner tank (88) sufficiently cool.

    摘要: The invention relates to a hydraulic elevator installation, comprising a counterweight, in which a cylinder (5) can be displaced along a piston rod (2). Said piston rod can be connected in a fixed manner to sections (1) of a building. The cylinder (5) has two pressure chambers (6, 7), between which hydraulic oil can be circulated, using a pump (9). This process displaces the cylinder (5) along the piston rod (2). The movement of the cylinder (5) is transmitted to a cabin (20) by means of a cable (21) which is guided over deflection pulleys (22, 23). In this assembly, the cylinder (5) forms part of the counterweight in relation to the cabin (20). According to the invention, the pump (9) and a motor which drives the same (12) are fixed to the cylinder (5) in such a way that these also function as part of the counterweight. The invention enables the complete hydraulic unit to be pre-assembled at the factory stage, to avoid maintenance work such as filling and air bleeding at the installation site. The invention can be advantageously used for elevator installations in buildings.

    摘要: The invention relates to a hydraulic elevator, comprising a pressure accumulator (17) which acts as a counterweight. In said elevator, hydraulic oil which can be supplied to or taken from a tank (14) can be conveyed using a first pump (12) through a pump line (11), at least one valve unit (7) and a cylinder line (6), to or from a hydraulic drive (2) for an elevator compartment (1) and can be conveyed using a second pump (15) via a solenoid valve (18) from or to the pressure accumulator (17). The two pumps (12, 15) are rigidly interconnected and can be driven by an electric motor (13). According to the invention, a single valve unit (7) is located between the first pump (12) and the hydraulic drive (2) which consists of a pilotable valve (8) and a first non-return valve, connected in parallel thereto (9). The rotational speed of the electric motor (13) can be regulated. A control and regulating unit (20) is also provided which acts upon a power regulator (21) for the electric motor (13), the solenoid valve (18) and in addition, the pilotable valve (8) during descent, in order to control and regulate the speed of the compartment (1). The invention relates to a hydraulic elevator of this type and to a method for controlling and regulating the same. The invention reduces the demand on the electric energy required to drive the motor (13) and thus to drive the hydraulic elevator.
