ShuangluanScisWhen a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door,ShuangluanElectric hoist, the door may not meet the above requirements,ShuangluanElectric mobile elevator, but safety should be maintained.
The pump body adopts an integrated pump station, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
Shuangluan.High altitude operations and maintenance in areas such as repair, logistics, electricity, petroleum, chemical, hotel,ShuangluanLarge electric elevator, sports center, mining and enterprise. The lifting system of the lifting platform is driven by hydraulic pressure, also known as hydraulic lifting
There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.
.Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
Monthly maintenance and inspection of hydraulic lifting platform rollers, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
Protective measures should comply with regulatory requirements.
8m； When the lifting speed is greater than 0.8m/s, after the upper limit switch is triggered by the hanging cage, 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
Later, when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.
Process inspection.Electric elevators used in various places.
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.
The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
knowledge.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.
The movement of its related components is direct.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
Shuangluan.Construction electric elevators outside the lightning protection range
During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements and record the inspection results.
After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, 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.
