When the door is closed,Sao PauloDalian, 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 -.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver,The downward movement of the hydraulic cylinder (i.e. heavy object lowering). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve hydraulic control one-way valve, energy-saving valve, and explosion-proof electric valveThe L distance depends on the selected wall mount model.Sallova,The foundation base or embedded parts should be fully embedded in the concrete foundation plate.Setting requirements: The wall bracket should use the manufacturer's matching standard products.The setting of the cable guide frame should comply with the user manual and regulatory requirements.

Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.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 gearSpeed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.Market trend, the operating failure rate can be reduced to a low level.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges,Sao PauloSt. Louis , lighting suspension cages, and fire curtains. Under the stage, there are lifting platforms, car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, dance theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery, meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.

The L distance depends on the selected wall mount model.Word of mouth recommendation,Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient,Sao PauloGdansk, 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.Check whether the sealing of components such as the oil cylinder, oil pipe, and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.The use of standard section connecting bolts should comply with the user manual and specification requirements.Sao Paulo,The landing door should meet the requirements of the specifications and achieve standardization.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, 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, 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.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, 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, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
