New SongqiMultThe L distance depends on the selected wall mount model.
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, it worked normally.
New Songqi.Equal effect.
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
.The use of standard section connecting bolts should comply with the user manual and specification requirements.
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.
Steel wire ropes, pulleys, wear, deformation, and corrosion of steel wire ropes
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,New SongqiElectric elevator 6 meters, etc.
The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
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.
Workshop cost.The 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.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
Protective measures should comply with regulatory requirements.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
how.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Normal operation starts. Click on this free download of construction technical information. Safety limit devices should be installed on electric elevators for construction,New SongqiElectric tatami elevator, with upper and lower limit switches that are sensitive and reliable.
The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.
New Songqi.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, 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.
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting,New Songqi3 meter small electric elevator, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Safety 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
