DaventelElectrThe advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Daventel.Setting requirements: Steel wire rope electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices which should have compliant loosening rope switches and be able to interrupt any movement of the cage until it passes through the
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, rate of increase and decrease. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to prevent hydraulic pipelines from exploding and self locking safely. Installed overloaded voice control alarm
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Customer first.Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
High lifting height, using side mounted oil cylinders,DaventelElectric elevator, stable operation, noise free, easy maintenance, using side mounted oil cylinders, stable operation,DaventelElectric one ton elevator, noise free, easy maintenance,DaventelSmall electric elevator platform, and longer service life.
Construction electric elevators outside the lightning protection range
Where can I find it?.Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Afterwards, it should be scrapped.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
Daventel.The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
