Before installation， the installation unit should confirm that the foundation， foundation bearing capacity， embedded parts，TaiyuanBrindisi，TaiyuanBogota， 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， and concrete strength report.
When the wall bracket cannot meet the requirements of the construction site， it should be designed and calculated separately.
TaiyuanSavings， 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
Setting requirements: Each landing entrance should be equipped with a landing door， which should cover the opening with its full width， and should not open towards the lifting passage.
RocklenSetting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications， as specified in the above table.
When the wall bracket adopts non matching standard products， design calculations should be carried out.
Setting requirements: The installation and dismantling workers， and other operators of construction electric elevators should have special construction operations.
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.
The upward movement of the hydraulic cylinder involves lifting heavy objects， and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment， 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，TaiyuanLublin， 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.
Inspection standardThe hydraulic oil forms a certain pressure by the vane pump， and enters the lower end of the hydraulic cylinder through an oil filter， explosion-proof electromagnetic directional valve， throttle valve， and balance valve， causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
Setting requirements: The landing door should be standardized and tooled.
Spiral electric lifting mechanism: With all the functions of a regular lifting platform， effective protective measures should be taken.
Setting requirements: Construction electric elevators should be equipped with a down travel (limit) switch. The down travel (limit) switch should be able to automatically stop the cage running at rated speed before reaching the lower limit switch.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only -mm and a travel distance of up to m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
device managementWhen 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， all components should be inspected， and standard sections and other components with severe wear and deformation should be replaced.
TaiyuanThe end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
From the perspective of the safety performance of the machinery itself， those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time， mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
The 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.
