Bohong3 meter electric elevatorGood insulation effect

Setting requirements: Before starting work every day and changing shifts,BohongInstallation of electric elevators for fire protection, 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.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.Bohong,BohongElevator electric small,When charging, it is necessary to charge it in a timely manner. When the equipment is used for about months (according to the actual frequency of use), it is necessary to add grease to the rotating parts once; Regularly inspect the working status of the pin shaft of the fully self-propelled electric elevator every month, and if any pin shaft is foundWhen applying a normal force of N to any position on either side of the door using a rigid mm square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test, it worked normally.Gardz,Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) 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.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 mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.

Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.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),When the door is closed except for the gap between the lower part of the door that should not exceed mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts,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.Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) 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.Setting requirements: The installation and dismantling workers, electricians and other operators of construction electric elevators should have special construction operations.

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, the hydraulic ground should be - 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 ( # 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.Quality improvement,The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.Requirements for the operation platform of the construction lowering machine and the setting of the brake reset emergency stop switch: The shutdown device (emergency stop switch) should be able to stop or maintain the electric elevator (including the power driven door) in a non working stateDrainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).Bohong,From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting low noise, large load bearing capacity, and are relatively simple
