In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
Frankfurt on main.Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
When the landing door is closed, the full width of the lifting passage opening should be covered.
.The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. 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 150mm.
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.
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter explosion-proof electromagnetic directional valve, throttle valve,Frankfurt on mainSmall electric elevator, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
Try to use this equipment in areas with wind force less than level five, and avoid using it when the wind force is too strong to avoid accidents.
Protective measures should comply with regulatory requirements.
Honesty and mutual benefit.It is understood that the scissor type lifting platform is a widely used specialized equipment for high-altitude operations. Its shear fork mechanical structure provides high stability for the lifting platform, wide working platform, and high load-bearing capacity, making the range of high-altitude operations larger and suitable for multiple people working simultaneously. The lifting power is divided into 24V, 220V or 380V power supplies, diesel engines, using Italian and domestic hydraulic pump stations, and the table top is equipped with anti slip insulation buckle plates, which have anti slip, insulation and safety features. Please rest assured to use.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
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.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
Application process.When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
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.
