Fort WorthElevSafety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
Fort Worth.The pressure joint between the pipe joint and the rubber hose fails prematurely, causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.
A complete lifting platform accessory can be selected and customized according to different places, venues, and environmental usage conditions. Meet the needs of different users. So why lifting platforms can be used and installed in so many industries and places is because they can achieve multi-purpose demonstrate multifunctional, meet various different needs, and win market demand. In modern industrial transportation processes, lifting platforms have begun to play an increasingly important role, whether in airports, docks, warehouses, floors, workshops and other places that require rapid loading and unloading of goods, they have played a very practical value, It has also brought great contributions to the entire industry and even the entire economic development. However, long-term operation and use of these devices inevitably lead to wear and consumption, and regular maintenance and upkeep are essential. Otherwise, and at that time, the gains and losses will outweigh the losses.
.Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm 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 4 of GB 23821-2009.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
With the continuous improvement of urbanization level in China, the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
The working principle of the aluminum alloy lifting platform is that hydraulic oil is composed of a vane pump to form a certain pressure, explosion-proof electromagnetic directional valve, throttle valve hydraulic control one-way valve, and balance valve
Setting requirements: For construction electric elevators with foundations installed on roof slabs floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.
management.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 8 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.
When the wall bracket adopts non matching standard products, 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, 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, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery,Fort WorthFixed electric elevator, 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.
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, 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.
Honesty and mutual benefit.High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.
The top of the hanging cage is accessible; d) During installation/disassembly/maintenance/inspection of the device; e) Inside the hanging cage.
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.
Fort Worth.Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion, Tower,Fort WorthMobile electric elevator, a hydraulic control one-way valve, also known as a hydraulic lock, 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 SB1&flash; The rotation of the SB6 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.
