Hydraulic freight elevator is a cargo lift driven by a hydraulic system, used for the straight transportation of goods between two or more points on a floor. Only for the purpose of transporting goods, personnel are strictly prohibited from riding.
In terms of civil engineering:
1. Hydraulic freight elevators do not require a high demand and high cost machine room above the shaft, and the roof can be level with the roof. However, the top floor of traditional machine room freight elevators needs to reach a net height of 4.2, while the top floor of machine room freight elevators needs to reach a net height of 4.5. In addition, the machine room above the top floor generally requires an area of more than 20 square meters and a height of about 2.8 meters.
2. The computer room is set up flexibly. The transmission system of hydraulic freight elevators relies on oil pipes to transmit power, so the location of the machine room can be set within a range of 20 meters from the shaft, and the machine room only occupies an area of 3-4 square meters.
3. The utilization rate of the well is high. Usually, hydraulic freight elevators do not have counterweight devices, which can improve the utilization rate of shaft area.
4. The strength requirement for the shaft structure is low. Due to the vertical loads such as the self weight and load of the hydraulic freight elevator car, all of which are applied to the foundation of the shaft through the hydraulic cylinder, the strength requirements for the walls and top of the shaft are relatively low. At the same time, its seismic resistance is stronger than that of ordinary elevators.
5. The hydraulic freight elevator adopts a low-noise screw pump, and the pump station and motor are designed as submersible structures, which can greatly reduce noise.
