The anti-rust work of the aerial work vehicle generally needs to be paid attention to when the aerial work vehicle has not been used for a long time. How should we do anti-corrosion for the body of the aerial work vehicle? This is actually very simple. You don’t need to spend money to go to the repair station for anti-corrosion. As long as our car owners use some materials that they can find at hand， it can be realized. At the same time paying attention to driving habits can ensure that the aerial work vehicle does not rust. Here are a few points that can be used as a reference.
How to effectively prevent electric shock by using a hydraulic lifting platform It is very common to add a leakage protector， and the cost is not high. It is both affordable and safe， and can effectively prevent electric shock.
BredaFirst of all， it is necessary to use and operate the elevator correctly， and provide systematic operation training for the operators: regular inspections of the operation specifications are required， and if any violation of the regulations is found， the elevator must be punished immediately， and those who are serious must be transferred from the post. Through the elevator production experience since the company， it is found that most elevator customers have overloaded elevators. Although the elevator has a large overload in design， the hidden dangers brought about by such use are very large， and it is easy to cause the oil cylinder to fall. ， lift bracket deformation and other injuries. Therefore， there must be the following summary: the maintenance of the elevator must be equipped with full-time elevator operators who have undergone on-the-job training， and illegal operations are strictly prohibited.
What is the new price of a fixed lift? Professionally improve the quality assurance of the freight elevator factory. The preferential activities are in progress， dismantling and adjusting the slewing mechanism， care should be taken to ensure that the centerline of the slewing mechanism reducer is parallel to the centerline of the gear， the meshing surface is not less than %， and the meshing clearance is suitable.
Before the elevator manufacturer connects the motor to the elevator， please make the keyway of the motor shaft perpendicular to the tightening bolt. In order to ensure uniform force， please screw on the mounting bolts at any diagonal position first， but do not tighten them tightly， then screw on the other two mounting bolts at diagonal positions， and then tighten the four mounting bolts one by one. Finally， tighten the tension bolts. All tightening bolts need a torque wrench to fix according to the marked fixed torque data and check whether the lift and lifting platform are used.How should we check the construction site of the construction hoist? you know?
Hydraulic system: mainly oil cylinders， high-strength chrome-plated rods， Japanese NOK seals self-made external integrated pump stations， oil pipelines， gear pumps， solenoid valves， etc. The Japanese NOK seal used in the oil cylinder has good wear resistance， which ensures that the oil cylinder series will not leak oil for a long time. The gear pump pumps the oil in the oil tank into the oil circuit and enters the oil cylinder， thereby driving the top of the rod and raising the equipment; The valve is used to adjust the oil output， the ascending and descending speed， and contains an emergency descending device to ensure that the guide rail hydraulic lifting platform can descend safely in case of an emergency.
Check the limit switch to see if all the limit switches are loose. If so， please tighten them. Pay special attention to the ultra-high protection stroke of the hydraulic lifting platform to avoid accidents caused by the equipment exceeding the high safety height; check the pins (ear pins and center pins) Check whether the nuts nuts， screws， if any should be reinforced immediately; ensure that the hydraulic lifting platform rises and falls smoothly; outriggers (for high-altitude operating platform)
Overview of manual hydraulic platform: Manual hydraulic platform is a small lifting mechanical platform， mainly used for small-scale lifting， lifting， moving and placing items， and also for handling small valuables. The appearance of the product is generous and beautiful， the structure is firm， stable， safe and reliable， and its performance and service life have reached the advanced level of the same equipment. At present， the mainstream of the market is hydraulic drive lifting. Due to its small size and convenient movement， it is widely used in logistics transportation， warehouse management， libraries， supermarkets， and ordinary small equipment manufacturing industries.
The water cooling of the hydraulic station is generally tube-type water cooling， and its type selection is based on the heat load to calculate the heat exchange area， while its air-cooled elevator is carried out by using an air cooler， and it is The heat transfer capacity is calculated according to the heat load， and then the type selection calculation is carried out under the condition that the flow rate can be satisfied. Therefore， these two kinds of cooling are not the same， and there is a big difference. Long-term promotion of freight elevator factories and other， Long-term cooperation， mutual benefit and win-win. If you choose the wrong supplier， you will be overwhelmed with all kinds of after-sales troubles in the later stage. Recently， I have seen many netizens report the problem of very loud oil cylinders. Today， the editor will simply popularize the knowledge for everyone.
howIn the construction elevator， the switch box also has leakage protection equipment. Its wires and cables are well insulated， without leakage， and the metal threaded is not rusted， and there is no problem of broken strands and diameter reduction. Of course， the number of broken wires should not exceed the corresponding standard. His pulley movement is very flexible.
The contact opening and closing of the travel switch of each safety device must be reliable， and the contact arc crater should be polished in time.
The last thing to note is that， compared with the lifting platforms in some places， protective fences are generally added on the platforms. Since the lifting platforms are special equipment， so when the personnel ask you if you want to add a guardrail， don"t blindly refuse， and consider whether it is necessary according to the site of use. In addition， you must have the "People"s Republic of Special Equipment Manufacturing License" and the "People"s Republic of Special Equipment Installation， Transformation and Maintenance License" to produce， install， and maintain. Therefore， you must ask whether the manufacturer has these two certificates.
Secondly， it needs to be washed off with gasoline or thinner; the gear box， gearbox， external gear and other parts of the equipment and the hydraulic oil must be in accordance with the requirements in the table; Correctly maintain the hydraulic guide rail lift. Regularly check whether the wire ropes in each part are broken or loose. If this phenomenon is found， replace them in time. If there is any looseness， to eliminate all faults in a timely manner; when installing whether there is noise or failure ， dismantling and adjusting the slewing mechanism of the equipment， it is necessary to pay attention to the parallelism between the reducer and the center line of the gear， and the appropriate meshing gap; conduct a comprehensive inspection of the equipment regularly， whether the wires and cables are If there is damage， whether the motor is overheated， replace it in time and continue to run after troubleshooting; ensure that the bearings of the motor， each box， distribution box and brushes must be kept clean， and the travel switch points of each safety device must be safe and reliable.
