by a riverMannheimHow to check the accuracy of machining work

When a rigid mm square or circular flat surface is applied with a normal force of N to either side of the door, the door may not meet the above requirements, but safety should be maintained.The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.by a river,by a riverAnam, disassembly including installation, and before resetting after action. Fall arrest safety gearIt is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easierWorcester,From the above comparison, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.Spiral electric lifting mechanism: With all the functions of a regular lifting platform,by a riverLa Rochelle , the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only -mm and a travel distance of up to m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.The foundation base or embedded parts should be fully embedded in the concrete foundation plate.

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 inner bearing of the roller in the device is in good condition, and a complete grease film surface is maintained between the curved surface of the roller and the main chord of the aluminum alloy electric elevator. A good grease film surface can reduce wear and noiseNews Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years, the products of electric lifting platform vehicles have been continuously improved, and various new technologies and materials have emerged, making the further development of lifting platform vehicles possible.resources,Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.

News Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years, the products of electric lifting platform vehicles have been continuously improved, and various new technologies and materials have emerged, making the further development of lifting platform vehicles possible.Inspection requirementsThere 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.In addition to fixed modes, there are also types of car mounted mobile devices. As the name suggests,by a riverBotou, this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move and of course, it is better to use it. For example, there are such lifting devices in airports, and car stations or sports stadiums may also be equipped with such devices, as they can be moved, So the scope of the operation is not limited to a specific place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.by a river,Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, 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, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
