the full width of the lifting passage opening should be covered.Revitalization and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed ohms; The power supply of the electric elevator can be cut off.When the landing door is closed

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,How to determine the sufficient amount of clean oil for the hydraulic station of an electric elevator? Why cannot water be used to flush the hydraulic station of an electric elevator?Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.Lodwar,Horizontal lead screw mechanical electricityFor 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: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.

The landing door should meet the requirements of the specifications and achieve standardization.Setting requirements: The up travel (limit) switch should be able to automatically stop the cage running at the rated speed before reaching the upper limit switch, but should not trigger the up travel (limit) switch as highThe landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.Latest consultation,Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise, 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 mm.The use of a lifting platform as a tool for storing performance blankets, soft scenery,RevitalizationFuli, 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, etc.

From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.production,Use floor doors and cage door devices on construction sites where conditions permit.Folding arm electric elevators are mostly driven by hydraulic means,RevitalizationSt. Louis , and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high,RevitalizationEd, can the folding arm electric elevator provide greater torque output, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?Acceptance: Concrete strength grade C, strength testing report.Revitalization,The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.
