JiningElectricHuman improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods,JiningSmall electric winch elevator, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
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.
Jining.The noise of aluminum alloy electric elevators during operation is relatively low. If the noise is high, it is abnormal. Therefore, it is necessary to do a good job in troubleshooting, find the cause in a timely manner reduce noise pollution, and reduce dangerous accidents
Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, 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
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter,JiningElectric aluminum alloy elevator, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, 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).
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
Pole
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Professional is king.Electric elevators used in various places.
Installation verticality deviation guide rail frame erection height h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
Before installation, 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.
When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
retailer.The scaffolding of the parking platform should be laid tightly and firmly.
Limit switches should be triggered directly by the movement of the suspension cage or its related components.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements,JiningElectric lifting scissor lift, but safety should be maintained.
Jining.Mechanical devices controlled by cage movement should not be used to open or close the landing door.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
Setting requirements: Before starting work every day and changing shifts, record the inspection results
