HartwanElectric elevators for elderly careWhat are the precautions for seasonal use

After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit,HartwanTwo phase electric elevator, and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.

Construction electric elevators outside the lightning protection range

Hartwan.The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area, while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then, the selection calculation is carried out under the condition of satisfying the flow rate. So,HartwanElectric bed elevator, these two types of cooling are different and have significant differences.

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.

.To meet the needs of choreographers and choreographers in different plays, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, creating unexpected atmosphere and effects according to the needs of the plot. For example using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.

Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

The quality of the standard section should comply with the product manual and specification requirements.

Try to use this equipment in areas with wind force less than level five, and avoid using it when the wind force is too strong to avoid accidents.

Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door

Excellent quality.Use floor doors and cage door devices on construction sites where conditions permit.

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,Hartwan6-12 meter fully automatic elevator, as specified in the above table.

Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.

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.

retailer.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, 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.

8m； When the lifting speed is greater than 0.8m/s, the upper small safety distance L should meet the following requirements: L=8+0.1V2, where L is the upper safety distance; V: Increase speed

The foundation base or embedded parts should be fully embedded in the concrete foundation plate.

Hartwan.The landing door should meet the requirements of the specifications and achieve standardization.

The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)

Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, 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.
