Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, 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, 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 then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above effective protective measures should be taken.
Foggia.Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output,FoggiaMobile small electric elevator, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
.It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
When the wall bracket adopts non matching standard products, design calculations should be carried out.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc. and the production should meet the design requirements.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high,FoggiaLadder type electric elevator,FoggiaFixed electric elevator, can the folding arm electric elevator provide greater torque output, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
Installation and dismantling personnel and drivers should hold certificates to work.
Executive standard.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.
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.
Then, the lifting platform platform platform that carries the load needs to be balanced, and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform, and the lifting of goods should try to maintain a stable and uniform speed.
Direct labor.Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
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),
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
Foggia.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
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.
Electric elevators used in various places.
