Elevator freight elevator guide rail elevator

Stability advantages:
1. Overflow valve: it can prevent the system pressure from being too high during upward movement.
2. Emergency manual valve: In case of power failure, the lift 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 out high-pressure oil to make the car rise to the nearest floor position.
4. Oil temperature protection of oil tank: when the oil temperature in the oil tank exceeds the standard setting value, the oil temperature protection device will send a signal, and the elevator will be suspended. When the oil temperature drops, the elevator can be started.
Operation cost advantage:
1. Low failure rate: due to the advanced hydraulic system and good control mode, the failure rate of elevator operation can be reduced to low.
2. Low power consumption: when the hydraulic elevator goes down, it is driven by the pressure generated by its own weight, which saves energy greatly.
