HandanStage elThe use of standard section connecting bolts should comply with the user manual and specification requirements.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
Handan.During maintenance or when problems occur, the power supply should be cut off in a timely manner. After lifting, the aluminum alloy electric elevator should be firmly fixed before maintenance can be carried out. It is strictly prohibited to operate with defects to avoid accidents.
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.
.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.
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.

Secondly, 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,HandanIndoor electric elevator,HandanFully automatic elevator electric, 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, maintain sufficient space,HandanElectric elevator for exterior wall decoration, and ensure that the lifting platform can be lifted to the rated lifting height.
. The shutdown device (emergency stop switch) should be installed outside the ground protective fence; b) Pulley room (if any. Pulley room refers to a room where only pulleys or speed limiters and electrical equipment are installed; c) hanging cage top, if
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.
Where can I find it?.Horizontal lead screw mechanical electricity
During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements, and record the inspection results.
Installation and dismantling personnel and drivers should hold certificates to work.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
Convenient and efficient.Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gauge
Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.
Handan.Principle of electric elevator rotary valve: When the electric elevator rises, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
Electric elevators used in various places.
