When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test,JinghaiTricycle electric elevator, it worked normally.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
Jinghai.Is there a relevant rule requirement for the cleanliness of hydraulic stations?
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, stable operation, 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.
.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 8 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.
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.
Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, the side protection device for the landing entrance should be equipped.
management.During normal operation, 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 150mm.
Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.
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 net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm,Jinghai200 kg portable electric elevator,JinghaiDedicated electric elevator, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
Market trend.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.
Greater than 0.04s; When the hydraulic buffer is used, the oil level shall be checked, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed, the cage shall not
Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.
Jinghai.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, 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 bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
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.
