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
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Qinghai.The body in the lateral adjustment device of the driving plate should ensure a compressed state, so that the gear has a certain radial constraint, and ensure that the gear and rack always mesh well throughout the entire operation.
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,QinghaiElectric elevator, 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.
.Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
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, but safety should be maintained.
If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every 6 months.
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.
Where can I find it?.Protective measures should comply with regulatory requirements.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station,QinghaiAutomatic elevator electric small, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.
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, hydraulic control one-way 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).
plan.From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
Only after the operation of professional personnel can the suspension cage movement be restored.
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.
Qinghai.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Secondly, for the replacement of hydraulic oil on the lifting platform it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged,QinghaiSmall hydraulic electric elevator, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
