From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Mingshan..
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
.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,MingshanElectric scissors elevator, 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, both work efficiency and utilization rate will decrease, and at that time the gains and losses will outweigh the losses.
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, the safety distance can be 0.40m.
Horizontal lead screw mechanical electricity
The upward movement of the hydraulic cylinder involves lifting heavy objects and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gauge
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.
Online consultation.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, 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.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.
Inspection environment.When the landing door is closed, the full width of the lifting passage opening should be covered.
Aluminum alloy lifting platforms can be divided into single column aluminum alloy, cargo elevator,MingshanMobile hydraulic electric elevator, double column aluminum alloy, three column and four column aluminum alloy. Can be used in factories, automated warehouses, parking lots, municipal facilities, docks, buildings and installations
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,MingshanElectric three wheel car lift, 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.
Mingshan.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, 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.

The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
