When the landing door is closed, the full width of the lifting passage opening should be covered.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 and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.Zhang Boli,Steel wire rope construction electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the lifting cage until it is approved by a professionalTo meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot,Zhang BoliIsirimurino, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.Las-Matas-de-Farfan,The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.To meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern, auxiliary lifting platforms are often arranged in front, back, left, and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable, so that the entire platform does not have a height difference, ensuring the safety of the cast members.Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, stable operation,Zhang BoliNewark , low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.

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.When a single steel wire rope is excessively stretched, the Electrical safety device shall stop the operation of the electric lift.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.Quotation sheet,Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.Mechanical devices controlled by cage movement should not be used to open or close the landing door.

The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.assetsThe pump body adopts an integrated pump station, all equipped with imported high-quality pump stations,Zhang BoliLe Valo Varpe, which can also be selected according to customer requirements to meet customer ideal requirements.The usual operation of landing and docking.Double layer steel mesh: The diameter of the steel bars is mm, with a spacing of mm.Zhang Boli,The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.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, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint remove the oil filter, and then return it to the oil tank and connect the pipeline.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
