dadIndoor elecThe oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
dad.Lower limit switch: In normal working state before the suspension cage touches the buffer, the lower limit switch first acts.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
.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.
Use floor doors and cage door devices on construction sites where conditions permit.
Model Example: Hanging Cage Specification: LABSC200/200TD3200x1500 Type I: 2900~3600 Type II: 2900~3600 Type V: 1800~250044003800 Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x0.02 (kN).
Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
When a single steel wire rope is excessively stretched,dad6m electric elevator,dadElectric brick elevator on construction site, the Electrical safety device shall stop the operation of the electric lift.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, a hydraulic control one-way valve,dadElectric lifting scissor lift, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Application process.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Before use, we should observe whether there is any damage to the electric elevator. We can conduct a no-load test to raise and lower it. If there are any damaged parts, they should be replaced in a timely manner to prevent major accidents.
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.
dad.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places, family dormitories and
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
