MarsonElectric brick elevator on construction siteAnalysis of the working principle

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.

When the landing door is closed, the full width of the lifting passage opening should be covered.

Marson.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.

Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops

.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.

The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.

Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, smooth lifting and low noise.

Setting requirements: Buffers should be installed below the suspension cage and counterweight running channel.

The use of standard section connecting bolts should comply with the user manual and specification requirements.

Good reputation.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,Marson10 meter electric lifting platform, 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.

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.

Work is essential,MarsonScissor fork electric lifting table, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.

The wall bracket of the construction electric elevator should be intact and reliably fixed,Marson12 meter electric elevator, and its attachment distance, wall bracket spacing, design its calculation sheet, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.

How much is it.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.

A lifting platform with specifications ranging in height from 1 meter to 20 meters.

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, 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.

Marson.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, 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).

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.

To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, 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.
