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.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.Yuanbao Mouytain,Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds % of the rated load capacity, the overload detection device will give a warning signal inside the cage,Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, 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.For customers to use and operate the lifting platform for a long time, the editor briefly introduces how to maintain and repair the lifting platform: First of all, normal maintenance is mainly focused on prevention especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems, resulting in costly repairs.Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.Stop.Speed 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),Yuanbao MouytainElectric cargo elevator, 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,Yuanbao MouytainMobile, andTrustworthy,Then, the lifting platform platform platform that carries the load needs to be balanced, and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform, and the lifting of goods should try to maintain a stable and uniform speed.Chain type electric lifting mechanism: With a good guiding mechanism, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.Safety and health,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.The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station,Yuanbao MouytainDedicated electric elevator, and once water is mixed in the hydraulic station, the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, water vaporization, and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore it is necessary to prevent such actions to ensure the normal operation and service life of the hydraulic station.The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets soft scenery, etc.Yuanbao Mouytain,From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, and are relatively simple, making them suitable for use in stage equipment.When the wall bracket adopts non matching standard products, design calculations should be carried out.There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least . meters.
Yuanbao MouytainElectric aluminum alloy elevator The goods have arrived, much better than what you see in the picture!
Yuanbao MouytainElectric aluminum alloy elevator Not bad, the price is worth it, just right.
The festival is coming soon, can Yuanbao MouytainElectric aluminum alloy elevator be discounted?
