HanshanElectric water gate elevatorVigorously advocate the maintenance of order

Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.

The L distance depends on the selected wall mount model.

Hanshan.Non automatic reset upper and lower limit switches should be installed at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers),

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.

.Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient,HanshanElectric screw elevator, 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.

According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, the side protection device for the landing entrance should be equipped.

Work is essential or a hall.

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, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.

The down travel (limit) switch should be of the automatic reset type.

Electric elevators used in various places.

reform.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.

The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.

In addition to ground protective fences, a half height middle crossbar, and a toe board at least 150mm above the ground.

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.

where.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 maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.

Afterwards, it should be scrapped.

Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.

Hanshan.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,HanshanElectric elevator for balcony, 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, 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.

During normal operation, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.

The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
