Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
In addition to ground protective fences， low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between m and m. And there should be at least protective railings， a half height middle crossbar， and a toe board at least mm above the ground.
AboniRequirements for the operation platform of the construction lowering machine and the setting of the brake reset emergency stop switch: The shutdown device (emergency stop switch) should be able to stop or maintain the electric elevator (including the power driven door) in a non working state
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 SB&flash; The rotation of the SB 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.
RusapeLater， when there is a major malfunction of the lifting platform， it should not be used again to avoid accidents， personnel and property losses.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances， when the net height of the building entrance is less than m， it is allowed to lower the height of the lower door opening， the net height of the lower door opening is not less than m. (Article of GB-)
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position， it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking， stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset， and installed in the machine room， rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
The usual operation of landing and docking. The installation position of the upper limit switch should comply with the following: when the lifting speed is less than .m/s， it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed，AboniManned electric elevator， and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion Terrace，AboniZoomlion Electric Elevator， Tower Pavilion; Ideal props.
Customer firstProtective measures should comply with regulatory requirements.
When the door is closed， except for the gap between the lower part of the door that should not exceed mm， any through-hole and opening size related to the distance between any door and adjacent moving parts， as well as the gap around the door or the gap between parts， should comply with the provisions of Table of GB -.
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations， making high-altitude operations easier
Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor)， which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places， family dormitories，Aboni2 meter micro electric lifting platform， and
Quotation sheetSetting requirements: For construction electric elevators that operate in multiple shifts， the handover system should be implemented and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.
Construction electric elevators should be equipped with emergency stop switches and comply with regulatory 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.
AboniAccording to the needs of different performance genres， the form of the stage can be changed. For example， using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater， using a lift can make the theater have various forms such as an end stage， an extended stage， an island stage， an intermediate stage， a T-shaped stage， or a hall.
Once again， weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened， whether the sealing rings are damaged or ineffective， whether there is a lack of hydraulic oil， and whether the oil cylinder is leaking. It is necessary to clean the lifting frame， scissors， wiring， and oil cylinder once a week to avoid dust and debris affecting normal operation.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends， it can automatically cut off the oil circuit and stop descent
