The main structure of the freight elevator is welded with high-strength rectangular tubes. It has the characteristics of high strength, large carrying capacity, stable lifting, simple and convenient installation, and maintenance, etc. It is an economical and practical low-rise elevator to replace the ideal equipment for cargo transportation. And what place does the freight elevator occupy in the modern elevator industry nowadays?
(1) Product advantages of freight elevators
- Low failure rate: Advanced hydraulic systems and good control methods can reduce the failure rate of elevator operation.
- Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.
(2) Advantages of freight elevator civil construction
1. There is no need for a machine room above the hoistway, and a height of 3.5 meters or more can be installed on the top floor.
2. The machine room can be located within a 15-meter radius of the hoistway, covering an area of only 3-4 square meters.
3. The hydraulic lift is not equipped with a counterweight device, which improves the utilization rate of the hoistway area.
4. The load and load of the hydraulic elevator act directly on the foundation pit through the oil cylinder, and the shaft strength is low. A brick structure or a brick-concrete structure is sufficient.
(3) Safe and stable advantages of freight elevators
1. Relief valve: can prevent the pressure from being too high when the system pressure rises
2. Emergency manual valve: In the event of a power failure, the car can be lowered to the nearest floor to open the door.
3. Manual pump: When the system fails, the manual pump can be operated to pump high-pressure oil to make the car ride to a closer floor.
4. Oil tank oil temperature protection: When the oil temperature in the oil tank exceeds the standard set value, the oil temperature protection device will generate a signal to suspend the use of the elevator, and only start the elevator when the oil temperature drops.
