Hejin6-meter e
HejinElevator 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,Hejin3 meter high electric elevator, 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.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
Hejin.Degrees, guardrails, protective covers, platforms and stairs, etc.
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,HejinMobile small electric elevator, 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,HejinFixed electric elevator, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
In addition, when adding hydraulic oil it is necessary to ensure the quality of the hydraulic oil, as some hydraulic oil manufacturers will choose hydraulic oil with poor quality. Hydraulic oil such as hydraulic lifting platforms not only cannot have any effect on folding arm elevators, but also affects the working efficiency of folding arm electric elevators due to deterioration issues.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
Test results.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Then, the lifting platform platform platform that carries the load needs to be balanced, 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.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
When the wall bracket cannot meet the requirements of the construction site it should be designed and calculated separately.
Promise and keep promise.Acceptance: Concrete strength grade C30, strength testing report.
Before installing the construction electric elevator, the foundation should be inspected and approved before installation.
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
Hejin.Protective measures should comply with regulatory requirements.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
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, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
