Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

Nai meiheng.In addition to fixed modes, there are also types of car mounted mobile devices. As the name suggests, this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move, and of course, it is better to use it. For example, there are such lifting devices in airports, as they can be moved, So the scope of the operation is not limited to a specific place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.

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.

.The counterweight guide rail should meet the specification requirements.

Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts,Nai meihengElevator scissor electric, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.

Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.

The impact load can cause early wear,Nai meihengElectric simple elevator, fracture, as well as generate impact pressure in the hydraulic system, which in turn can damage hydraulic components, oil seals,Nai meihengLadder type electric elevator, and high-pressure oil

Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.

Energy costs.Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.

Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.

Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.

The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.

Interpretation and observation.Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.

The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station, and once water is mixed in the hydraulic station the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore, it is necessary to prevent such actions to ensure the normal operation and service life of the hydraulic station.

Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.

Nai meiheng.Model Example: Hanging Cage Specification: LABSC200/200TD3200x1500 Type I: 2900~3600 Type II: 2900~3600 Type V: 1800~250044003800 Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x0.02 (kN).

Electric elevators used in various places.

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