MaslesSmall electric pulley elevatorAnalysis of the role played in the industry

Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form,MaslesElectric bed elevator, and concrete strength report.

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

Masles.It is strictly prohibited to use travel limit switches as switches to stop operation.

Protective measures should comply with regulatory requirements.

.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.

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).

Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.

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

A lifting platform with specifications ranging in height from 1 meter to 20 meters.

Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, etc. In some theaters soft scenery, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.

Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.

The use of standard section connecting bolts should comply with the user manual and specification requirements.

To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.

Supply chain quality management.Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.

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

Stage equipment safety door. To prevent personnel from extending their heads,MaslesElectric elevator 6 meters, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors,MaslesElectric spiral rod elevator, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.

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

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.

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