BeijingFloor lift cargo elevatorCommon sense of tool use

Always check all wires and cables for damage. The damaged part should be bandaged and replaced in time.Precautions for elevator installation Keep the access road of the external construction elevator smooth and have enough parking space for equipment. When it is necessary to use a steam crane for auxiliary installation,BeijingFixed lifting hydraulic cargo elevator, it should be fully considered whether the site environment meets the operating conditions of the steam crane.Beijing,Relief valve: It can realize the effect of blocking the flow of oil passage and diverting flow. It is often used if the oil pipe bursts, causing the equipment to drop sharply and causing serious losses.The use of elevators is not to maintain and overhaul after the equipment fails. It is necessary to maintain the equipment according to the correct maintenance and overhaul, and start with the preparation work to prevent all possible failures and accidents. I hope that the editor can summarize the knowledge points today. Help everyone.Traiguen,Frequently check whether the various mechanisms are operating normally and whether there is any noise. If a fault is found it must be eliminated in time.The parts such as reduction box, gearbox, external gear and hydraulic oil are all in accordance with the requirements in the table.The wrong connection of the motor of the elevator When a coil, coil group or one-phase winding is reversed, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.

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.Cleaning and keeping it clean is the first priority. Regularly clean up the dust or sundries on the motor of the hydraulic lifting platform, otherwise the long-term accumulated dust will fall into the motor fan,BeijingLifting cargo elevator 1 ton, and it will be very difficult to run, just like the laptop we usually use. If the dust on the computer fan is not cleaned, the computer will not be easy to dissipate heat, or even buzz. It will be much better after cleaning, and the same is true for the motor of the hydraulic lifting platform. V or V; how to properly maintain the motor of the hydraulic lifting platform to avoid the motor, of course, it is safer to keep away from the water for things related to electricity, do not use it outdoors in rainy and snowy weather,BeijingGuide rail type lifting cargo elevator, etc., it must not be overloaded, which will bring a burden to the motor, and it may burn out the motor; At this time, you may wish to consult the manufacturer about the overload protection device. The overload protection device is generally selected by the manufacturer. After adding this device, you don’t have to worry about whether it is overloaded during use. It is not too expensive to add this device. Safe, more at ease); can not adjust the overflow valve (also known as 'solenoid valve')In addition to the fixed mode, and of course it is more useful. For example There is this kind of lifting equipment in the airport it combines the lifting equipment with the vehicle-mounted system. Such a lifting equipment is very flexible to move, and it is also possible to install this kind of equipment in stations or stadiums. Since it can be moved, the scope of operation is not limited to a certain place, and it can be used wherever lifting operations are required. It can be used. For example, when installing outdoor advertisements, the height of some advertisements is relatively high. At this time, mobile lifting equipment can be used to send billboards or staff to the designated height to work. This kind of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is driven by hydraulic oil to reach a specified height. The electric mode is driven by a motor or geared to lift to A certain height, but at present, hydraulic lifting platforms are more widely used.Administration,This kind of fixed lifting equipment can also be used in the warehouse. For example, a certain floor in the warehouse needs to be lifted to send goods or personnel into the designated warehouse.Check the front page of the oil pipe to check whether the skin of the oil pipe of the hydraulic lifting platform is damaged or cracked, and if so, replace it immediately; secondly, check whether there is any sign of looseness at the connection between the oil pipe and the oil pipe, and if so, tighten it immediately to avoid lifting on the hydraulic lifting platform There is an oil spill in the process, which leads to accidents; what items need to be checked before using the hydraulic lifting platform? Cut off the power first to avoid tragedies such as electric leakage and electric shock)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, etc. are loose, if any, should be reinforced immediately; ensure that the hydraulic lifting platform rises and falls smoothly; outriggers (for high-altitude operating platform)

Conscientiously write the special construction plan for installation and construction, and make safety technical disclosures to the installers.Potential development,The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding, the short-circuit current is much larger than the normal operating current, which increases the copper loss of the winding, and if it is found that the oil is foaming or turbid, it should be replaced in time. The performance of the professional elevator factory is stable, safe, reliable, and can be maintenance-free. The technical level has reached the domestic level and the international advanced level of similar products.The hydraulic lifting platform can be divided into: four-wheel mobile type, two-wheel traction type, car modified type, car type, auxiliary self-propelled type, and the lifting height ranges from a meter to s meter.Beijing,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, 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?The wrong connection of the motor of the elevator When a coil, coil group or one-phase winding is reversed, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.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, the National Quality Inspection Bureau is very strict on this piece of inspection. All must be dismantled, 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, Transformation and Maintenance License' to produce, install, and maintain. Therefore, you must ask whether the manufacturer has these two certificates.
