PreacherGuide Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, 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
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
.Monthly maintenance and inspection of hydraulic lifting platform rollers,PreacherMicro electric elevator, intermediate shafts and bearings oil cylinder pin shafts and bearings,PreacherCurved arm electric elevator, 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, then install it and reinstall it. Drain and discard the hydraulic oil, 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 setting of the cable guide frame should comply with the user manual and regulatory requirements.
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,PreacherFully electric scissor lift, the side protection device for the landing entrance should be equipped.
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 usual operation of landing and docking.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
index.Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
Model Example: Hanging Cage Specification: LABSC200/200TD3200x1500 Type I: 2900~3600 Type II: 2900~3600 Type V: 1800~250044003800 Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x0.02 (kN).
Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
The L distance depends on the selected wall mount model.
Standard requirements.The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
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, these two types of cooling are different and have significant differences.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Preacher.During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
