The quality of the standard section should comply with the product manual and specification requirements.The motor of the hydraulic guide rail lifting platform is set around the wellbore, improving the utilization rate of the wellbore area.Lumia ,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.Mechanical devices controlled by cage movement should not be used to open or close the landing door.Inhambane,Later, when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.Principle of electric elevator rotary valve: When the electric elevator rises, 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.The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.

The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every months.Once again, whether there is a lack of hydraulic oil whether the sealing rings are damaged or ineffective and whether the oil cylinder is leaking. It is necessary to clean the lifting frame,Lumia Sividnica, scissors, and oil cylinder once a week to avoid dust and debris affecting normal operation.Latest consultation,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,Lumia Cangzhou, 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.During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed mm.The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

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,Lumia PSV Eindhoven, 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.Discount,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, clean it with compressed air, and then return it to the oil tank and connect the pipeline.Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of meters by meters.Lumia Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered downThe quality of the standard section should comply with the product manual and specification requirements.Double layer steel mesh: The diameter of the steel bars is mm, with a spacing of mm.
