The lifting stage is a high-altitude operation equipment and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers, it is necessary to regularly inspect the lifting stage and tighten any loose components. The lifting stage is a high-altitude operation equipment, it is necessary to regularly inspect the lifting stage and tighten any loose components. The interference and hazard analysis of the frequency conversion speed regulation construction elevator circuit is becoming increasingly widespread in the development of technology today. Variable frequency speed regulation has the characteristics of stable start and stop process, reducing mechanical shock, increasing the comfort of passengers, and improving the service life. At the same time, it can also change the speed of power supply frequency regulation, save electric energy, and improve work efficiency. However, there will be interference in the use of variable frequency speed regulation system, which will often cause safety accidents of construction elevator.Please refer to the instruction manual for the maintenance and maintenance of the elevator to check the braking torque of the brakeBohong,Power supply voltage: Motor power: Lifting: Rocker self reset switch operation Overload protection: Over current relay.On the contrary, loosen the connecting nut of the eccentric shaft of the guide roller and the tooth back pressure wheel as shown in , adjust the tooth back pressure wheel to press towards the back plane of the gear rack until the backlash reaches a reasonable range. Otherwise, it should be adjusted in the opposite direction. At this point, the guide roller should be loosened for o and then adjusted according to the adjustment of the guide roller.Katamaka,After cleaning, clean the filter and replace it with a new filter element before adding new oil. What adverse reactions may occur during the early use of hydraulic cargo elevators?　　?? Hidden danger investigation relies on joint efforts from all aspects:?? Construction enterprises are the main responsibility for identifying hidden dangers in construction elevators. They should strengthen daily inspections and regular inspections, and carefully inspect the steel structure, safety protection devices, electrical devices, and transmission devices of construction elevatorsAdjust and correct various safety doors and mechanical interlocking equipment

Lifting and loweringHowever, large welded structural components have the characteristics of complex morphology, large weight, large differences in residual stress size and distribution, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH- vibration aging equipment,BohongSingle mast aluminum alloy lifting platform, and requested us to develop a complete vibration aging process.　　?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities, it shall be ordered to evacuate workers from the hazardous area or temporarily stop construction. In the work of hazard investigation and control, the investigation shall be serious, the rectification shall be resolute, and the results shall be consolidated.How much is it,Check the interlocking equipment, up and down travel, and other safety maintenance switches of the cage door and fence doorRegarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracketCheck all standard sections and diagonal support connection points. Check the fastening bolts of the gear rack and ensure that the motor cooling wing plate and organization are clean

The surface of each part of the brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than %.Quality recommendation,Transfer of goods between floors of rooms, restaurants, and restaurants. The low height is between -mm especially suitable for workplaces that cannot excavate pits. And there is no need for upper lifting points, with diverse forms (single column, double column, four column), stable equipment operation, simple and reliable operation, economic and convenient goods transmission, and difficult to solve narrow spaces that cannot reach the requirements. A customized delivery platform can be created,BohongSelf propelled mobile lifting platform, and the product hydraulic system is equipped with anti fall, and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point. The product has a sturdy structure, a large load-bearing capacity, smooth lifting, simple and convenient installation and maintenance, making it an ideal and economical cargo conveying equipment for replacing elevators between low floors. The lifting stage device is mainly responsible for data processing of the operation mechanism and work bar of the vehicle, calculating the safety area of the lifting stage, and is suitable for the electric control system of the self lifting stage lifting platform. The main sensors in the electric control system include angle sensors, long angle sensors, dual axis inclination sensors, and energy saving of the oil cylinder system.Emergency stop: Press the emergency button switch to raise or lower the machine.There are many operational errors, and due to insufficient understanding of the structure and performance of the machine (especially for new operators), it is easy to cause malfunctions and even mechanical accidents due to operational errors. How to calculate the lifting cargo elevator? A lifting cargo elevator is a heavy lifting mechanical equipment that can manually operate the system's buttons to complete the transportation of goods up and down. The lifting height of the lifting cargo elevator varies from meter to meters, and special specifications of lifting and lowering cargo elevators can be customized according to user requirements According to the type, it can be divided into:; Scissor fork type cargo elevator and guide rail type cargo elevator. Guide rail type elevator is a non scissor fork type cargo elevator, mainly used for the transportation of goods between floors of workshops, steel structure workshops hotels, rooms, and warehouses without pits or machine rooms. Scissor fork type cargo elevators need to be prepared with pits before installation and the elevator should be fixed and connected in the pit before being connected to the power supply The lifting cargo elevator utilizes hydraulic power units to generate pressure during operation,BohongSelf folding arm lifting platform, which drives the hydraulic oil cylinder as the main power to raise and lower the lifting cargo elevator platform. When a guide rail type hydraulic lifting cargo elevator malfunctions it can immediately stop running, with high safety and stability. The driving of the hydraulic power unit makes it have strong load-bearing capacity and smooth lifting, which can achieve the transportation of large tonnage goodsBohong,Regarding the construction elevator with counterweight, check the adjustment and fixation status of the counterweight guide wheel. Check the balancing equipment of the steel wire rope, the crown wheel, and the counterweight steel wire rope bracketCheck the relative orientation between the cable support wall and the cable guide frameCheck the fastening status of the wall bracket, support rod, they should be checked and tightened
