neutralBasement electric elevatorHow does it work?

and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve

The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional 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.

Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, the overload detection device will give a warning signal inside the cage,

When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.

.From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple,neutralElectric elevator 5 meters, making them suitable for use in stage equipment.

The quality of the standard section should comply with the product manual and specification requirements.

Low power consumption: When the hydraulic guide rail lifting platform descends, it is driven by the pressure generated by its own weight, greatly saving energy and reducing consumption.

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.

After the limit switch is activated, only professional personnel can restore the movement of the suspension cage; Limit switches and travel switches should not share the same triggering element; Limit switches should be either suspended or

Mechanical devices controlled by cage movement should not be used to open or close the landing door.

market.The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.

To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.

Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.

Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.

Quality Assurance.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.

Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.

Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.

neutral.The verticality of the guide rail frame should meet the requirements of the specifications.

Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).

Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors,neutralElectric banner elevator, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked.
