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， 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 degree position until it is closed， and then turn the transmission handwheel to lower the plug and achieve sealing.
Hui CenThere is a certain itinerary.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site， it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness strength， stability etc.， all components should be inspected，Hui CenSilverson， and standard sections and other components with severe wear and deformation should be replaced.
It is understood that the scissor type lifting platform is a widely used specialized equipment for high-altitude operations. Its shear fork mechanical structure provides high stability for the lifting platform， wide working platform， and high load-bearing capacity， making the range of high-altitude operations larger and suitable for multiple people working simultaneously. The lifting power is divided into V， V or V power supplies， diesel engines， using Italian and domestic hydraulic pump stations， and the table top is equipped with anti slip insulation buckle plates， which have anti slip， insulation，Hui CenHuairen， and safety features. Please rest assured to use.
Double layer steel mesh: The diameter of the steel bars is mm， with a spacing of mm.
Monthly maintenance and inspection of hydraulic lifting platform rollers， intermediate shafts and bearings， oil cylinder pin shafts and bearings， boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process， and at this position， the hydraulic ground should be - millimeters higher than the bottom of the box. If the hydraulic oil becomes dark， sticky， or has foreign objects such as gravel it should be replaced in a timely manner ( # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged， and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform， then install it and reinstall it. Drain and discard the hydraulic oil， tighten the joint，Hui CenNashville， remove the oil filter， clean it with compressed air， and then return it to the oil tank and connect the pipeline.
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
Stage equipment safety door. To prevent personnel from extending their heads， 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， and the height of the hoistway (hall door) should not be less than meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical， passenger car doors， which must open towards the landing platform side， and the door bolt must be set on the side next to the construction electric elevator.
Acceptance: Concrete strength grade C， strength testing report.
Setting 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.
Horizontal lead screw mechanical electricity
Total quality assuranceSpeed 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， and
Construction electric elevators should be equipped with safety devices to prevent the cage from falling. The anti fall safety device should be functional at all times， including installation， disassembly， and before resetting after action. Fall arrest safety gear
During loading and unloading， the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed mm.
Hui CenWork is essential and the main protective accessories include safety belts， guardrails， protective covers， platforms and stairs， etc.
Model Example: Hanging Cage Specification: LABSC/TDx Type I: ~ Type II: ~ Type V: ~ 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) x. (kN).
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient， and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure， small size， and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
