Zhang Boli2 meThe pump body adopts an integrated pump station, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
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)
Zhang Boli.Equal effect.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends it can automatically cut off the oil circuit and stop descent
.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s,Zhang BoliElevator electric small, the safety distance can be 0.40m.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
Stage equipment safety door. To prevent personnel from extending their heads hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
.
During normal operation, 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.
quality standard.The pump body adopts an integrated pump station, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges, lighting suspension cages, and fire curtains. Under the stage there are lifting platforms, car platforms,Zhang BoliElectric guide rail elevator, turntables,Zhang BoliMobile small electric elevator, and lifting orchestras. Some lifting platforms are equipped with turntables, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery, meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
High lifting height, using side mounted oil cylinders, stable operation, easy maintenance, and longer service life.
Administration.Work is essential, and the main protective accessories include safety belts, guardrails protective covers, platforms and stairs, etc.
Check whether the sealing of components such as the oil cylinder, oil pipe, and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
Zhang Boli.The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
Then, and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform, and the lifting of goods should try to maintain a stable and uniform speed.
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, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, 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.
